Central's XmtGlobal is drained at 4 +packets per 10ms; the buffer only needs capacity for burst scenarios like CCF file loading. + +### Packet Format in Native Shared Memory + +All packets in native shared memory are in **current protocol format** (4.2+). Protocol +translation happens at the cbdev layer before packets reach shared memory: + +``` +Device (any protocol) --> cbdev DeviceSession wrapper --> translates to current format + --> writes current-format packets to native shmem + --> CLIENTs read current format (no translation needed) +``` + +This means CLIENT processes never need to know what protocol the device speaks. + +## Central Compat Mode + +When CereLink detects that Central is running (by checking for Central's system mutex +`cbSharedDataMutex`), it attaches to Central's existing shared memory as a CLIENT. + +### Segment Names (Central's) + +Central uses instance-0 bare names: +- `cbCFGbuffer`, `cbRECbuffer`, `XmtGlobal`, `XmtLocal`, `cbSTATUSbuffer`, `cbSPKbuffer`, + `cbSIGNALevent` + +CereLink only supports Central instance 0. Instances 1-3 are not supported. + +### DeviceType to Instrument Index Mapping + +Central's config buffer has `[4]` arrays for up to 4 instruments. CereLink must map +`DeviceType` to the correct instrument index in Central's arrays. + +The mapping is hardcoded based on Central's compile-time `GEMSTART` setting. The current +Central build uses `GEMSTART == 2`: + +| Instrument Index | Device | IP Address | Port | +|-----------------|--------|------------|------| +| 0 | Hub 1 | 192.168.137.200 | 51002 | +| 1 | Hub 2 | 192.168.137.201 | 51003 | +| 2 | Hub 3 | 192.168.137.202 | 51004 | +| 3 | NSP | 192.168.137.128 | 51001 | + +**Limitation**: This mapping assumes Central was compiled with `GEMSTART == 2`. An alternate +build (`GEMSTART == 1`) uses a different ordering: NSP=0, Hub1=1, Hub2=2. CereLink does +not currently detect or adapt to alternate GEMSTART configurations. If a future Central +build changes GEMSTART, this mapping must be updated. A runtime discovery mechanism (e.g., +scanning `procinfo` slots for identifying data) could be added if needed. + +For legacy (non-Gemini) NSP systems, only instrument index 0 is used. + +### Receive Buffer Filtering + +In Central's shared memory, ALL devices' packets go into ONE receive ring buffer. When +CereLink compat mode is reading for a specific device: + +1. Read all packets from `cbRECbuffer` (cannot filter at the shmem level) +2. Check each packet's `cbpkt_header.instrument` field +3. Deliver only packets matching the requested device's instrument index + +This is less efficient than native mode (where the receive buffer only contains one device's +packets), but the large buffer size makes this a negligible cost. + +### Protocol Translation in Compat Mode + +Central only supports one protocol version at a time. Packets in Central's shared memory +are in whatever protocol format Central is using, which may be older than CereLink's current +format (4.2+). + +When reading from Central's shared memory, CereLink must: +1. Detect the protocol version (from `cbCFGBUFF.sysinfo` version field) +2. Translate packets from old format to current format using `PacketTranslator` +3. Deliver current-format packets to the user callback + +When writing to Central's transmit buffer, the reverse translation applies. + +This reuses the same `PacketTranslator` infrastructure that `cbdev` uses for direct UDP +connections to older devices. + +### Config Buffer Access in Compat Mode + +Central's `cbCFGBUFF` has a different field layout than CereLink's `NativeConfigBuffer` or +`cbConfigBuffer` (see "Differences from Central" section below). In compat mode, CereLink +must use a `CentralLegacyCFGBUFF` struct that matches Central's exact field order to read +the config buffer correctly. + +Config access for a specific device uses the instrument index: +``` +cfg->procinfo[instrument_idx] +cfg->bankinfo[instrument_idx] +cfg->filtinfo[instrument_idx] +// etc. +``` + +## Mode Auto-Detection + +``` +SdkSession::open(DeviceType::HUB1) + | + +-- Can open Central's "cbSharedDataMutex" (instance 0)? + | | + | YES --> Central Compat Mode + | - Map Central's 7 instance-0 segments + | - Use GEMSTART==2 mapping: Hub1 = instrument index 0 + | - Filter receive buffer by instrument field + | - Translate packets if protocol version < current + | - Index into [4] arrays for config access + | + +-- NO --> Can open "cbshm_hub1_signal"? + | | + | YES --> Native Client Mode + | - Map cbshm_hub1_* segments (read-only) + | - All packets are Hub1's (no filtering) + | - Packets in current format (no translation) + | - Config is single-instrument (no indexing) + | + +-- NO --> Native Standalone Mode + - Create cbshm_hub1_* segments + - Start cbdev (protocol auto-detect + translation) + - Write current-format packets to native shmem + - Other CLIENTs can attach via Native Client Mode ``` ## Key Data Flow Paths -### Device → STANDALONE → Shared Memory → CLIENT +### Device -> STANDALONE -> Shared Memory -> CLIENT -1. **NSP device** sends UDP packet (port 51002) +1. **NSP device** sends UDP packet 2. **STANDALONE UDP receive thread** catches packet -3. **onPacketsReceivedFromDevice()**: - - `storePacket(pkt)` writes to `cbRECbuffer[headindex]` +3. **cbdev** translates packet to current protocol format (if device uses older protocol) +4. **onPacketsReceivedFromDevice()**: + - `storePacket(pkt)` writes to receive buffer `[headindex]` - `headindex++` (advance writer position) - - `signalData()` → Set `cbSIGNALevent` (wake up CLIENTs!) -4. **CLIENT shmem receive thread** wakes up from `waitForData()` -5. **CLIENT** calls `readReceiveBuffer()`: - - Read from `cbRECbuffer[tailindex]` to `cbRECbuffer[headindex]` + - `signalData()` -> Set signal event (wake up CLIENTs!) + - Enqueue to SPSC queue for callback dispatcher thread +5. **CLIENT shmem receive thread** wakes up from `waitForData()` +6. **CLIENT** calls `readReceiveBuffer()`: + - Read from receive buffer `[tailindex]` to `[headindex]` - `tailindex += packets_read` (advance reader position) - Parse packets from ring buffer (handle wraparound) -6. **CLIENT** enqueues packets to local `packet_queue` -7. **Callback dispatcher thread** invokes user callback +7. **CLIENT** invokes user callback **directly** (no queue, no 2nd thread needed) -### CLIENT → Shared Memory → STANDALONE → Device +### CLIENT -> Shared Memory -> STANDALONE -> Device 1. **Client app** calls `sendPacket(command)` -2. `enqueuePacket()` writes to `XmtGlobal` transmit queue -3. **STANDALONE send thread** dequeues from `XmtGlobal` -4. **Send thread** transmits packet via UDP to device (port 51001) +2. `enqueuePacket()` writes to transmit queue +3. **STANDALONE send thread** dequeues from transmit queue +4. **Send thread** transmits packet via UDP to device -## Synchronization (cbSIGNALevent) +## Synchronization ### STANDALONE (Producer) - Calls `signalData()` after writing packets @@ -154,13 +357,13 @@ CereLink implements a Central-compatible shared memory architecture that enables ### Efficiency - CLIENT sleeps until signaled (no CPU-burning polling!) - Immediate wakeup when new data arrives -- Matches Central's `cbWaitforData()` behavior ## Ring Buffer Tracking ### Overview -- `cbRECbuffer` is a ring buffer with wrap-around capability -- ~200MB buffer size (`CENTRAL_cbRECBUFFLEN` = 768 * 65536 * 4 - 1 dwords) +- Receive buffer is a ring buffer with wrap-around capability +- Native mode: 256 * 65536 * 4 - 1 dwords (~256 MB per device) +- Central compat: 768 * 65536 * 4 - 1 dwords (~768 MB, all devices combined) ### Writer (STANDALONE) - Updates `headindex` - current write position @@ -181,145 +384,152 @@ CereLink implements a Central-compatible shared memory architecture that enables - Variable-length packets - Handles wraparound mid-packet (copy in two parts) -## Process Modes - -### STANDALONE Mode -- **First process** to start -- **Creates** shared memory segments -- **Owns** device connection (UDP threads) -- **Writes** to `cbRECbuffer` (producer) -- **Signals** `cbSIGNALevent` when data written -- **Dequeues** from `XmtGlobal` and transmits to device - -### CLIENT Mode -- **Subsequent processes** that attach -- **Attaches** to existing shared memory -- **No device** connection (no UDP threads) -- **Reads** from `cbRECbuffer` (consumer) -- **Waits** on `cbSIGNALevent` for new data -- **Enqueues** to `XmtGlobal` to send commands (STANDALONE transmits them) - -### Auto-Detection -The SDK automatically detects mode: -1.

-## Getting Started - -* Download a wheel from the releases page or [build it yourself](#build-instructions). -* Activate a Python environment with pip, Cython, and numpy -* Install the wheel: `python -m pip install path\to\filename.whl` -* Test with `python -c "from cerelink import cbpy; cbpy.open(parameter=cbpy.defaultConParams())"` - * You might get `RuntimeError: -30, Instrument is offline.`.

All rights reserved. -/// -/// @author Kirk Korver -/// @date 2002 -/// -/// @brief Definition of the Neuromatic library protocols. -/// -/// This code library defines a standardized control and data access interface for microelectrode -/// neurophysiology equipment. The interface allows several applications to simultaneously access -/// the control and data stream for the equipment through a central control application. This -/// central application governs the flow of information to the user interface applications and -/// performs hardware specific data processing for the instruments. This is diagrammed as follows: -/// -/// Instruments <---> Central Control App <--+--> Cerebus Library <---> User Application -/// +--> Cerebus Library <---> User Application -/// +--> Cerebus Library <---> User Application -/// -/// The Central Control Application can also exchange window/application configuration data so that -/// the Central Application can save and restore instrument and application window settings. -/// -/// All hardware configuration, hardware acknowledgement, and data information are passed on the -/// system in packet form. Cerebus user applications interact with the hardware in the system by -/// sending and receiving configuration and data packets through the Central Control Application. -/// In order to aid efficiency, the Central Control App caches information regarding hardware -/// configuration so that multiple applications do not need to request hardware configuration -/// packets from the system. The Neuromatic Library provides high-level functions for retrieving -/// data from this cache and high-level functions for transmitting configuration packets to the -/// hardware. Neuromatic applications must provide a callback function for receiving data and -/// configuration acknowledgement packets. -/// -/// The data stream from the hardware is composed of "neural data" to be saved in experiment files -/// and "preview data" that provides information such as compressed real-time channel data for -/// scrolling displays and Line Noise Cancellation waveforms to update the user. -/// -/// Central Startup Procedure: -/// On start, central sends cbPKT_SYSINFO with the runlevel set to cbRUNLEVEL_RUNNING -/// The NSP responds with its current runlevel (cbRUNLEVEL_STARTUP, STANDBY, or RUNNING) -/// At 0.5 seconds Central checks the returned runlevel and sets a flag if it is STARTUP for other -/// processing such as autoloading a CCF file. Then it sends a cbRUNLEVEL_HARDRESET -/// At 1.0 seconds Central sends a generic packet with the type set to cbPKTTYPE_REQCONFIGALL -/// The NSP responds with a boatload of configuration packets -/// At 2.0 seconds, Central sets runlevel to cbRUNLEVEL_RUNNING -/// The NSP will then start sending data packets and respond to configuration packets.= -/// -/////////////////////////////////////////////////////////////////////////////////////////////////// - -// Standard include guards -#ifndef CBPROTO_H_INCLUDED -#define CBPROTO_H_INCLUDED - -// Only standard headers might be included here -#if defined(WIN32) -// It has to be in this order for right version of sockets -#ifdef NO_AFX -#include -#include -#endif -#endif // WIN32 - -#ifdef __KERNEL__ -#include -#else -#include -#endif - -#pragma pack(push, 1) - -#ifdef CBPROTO_311 -#define cbVERSION_MAJOR 3 -#define cbVERSION_MINOR 11 -#else -#define cbVERSION_MAJOR 4 -#define cbVERSION_MINOR 1 -#endif - -// Version history: -// - 03 Feb 2023 hls - Separate protocol structures into new file cbProto.h -// 4.1 - 14 Mar 2022 hls - Update CHANINFO to be a multiple of 32-bits.

This is - * a very useful and long desired include file which contains several - * very precise definitions for integer scalar types that is critically - * important for making several classes of applications portable - * including cryptography, hashing, variable length integer libraries - * and so on. But for most developers its likely useful just for - * programming sanity. - * - * The problem is that some compiler vendors chose to ignore the C99 - * standard and some older compilers have no opportunity to be updated. - * Because of this situation, simply including stdint.h in your code - * makes it unportable. - * - * So that's what this file is all about. It's an attempt to build a - * single universal include file that works on as many platforms as - * possible to deliver what stdint.h is supposed to. Even compilers - * that already come with stdint.h can use this file instead without - * any loss of functionality. A few things that should be noted about - * this file: - * - * 1) It is not guaranteed to be portable and/or present an identical - * interface on all platforms. The extreme variability of the - * ANSI C standard makes this an impossibility right from the - * very get go. Its really only meant to be useful for the vast - * majority of platforms that possess the capability of - * implementing usefully and precisely defined, standard sized - * integer scalars. Systems which are not intrinsically 2s - * complement may produce invalid constants. - * - * 2) There is an unavoidable use of non-reserved symbols. - * - * 3) Other standard include files are invoked. - * - * 4) This file may come in conflict with future platforms that do - * include stdint.h. The hope is that one or the other can be - * used with no real difference. - * - * 5) In the current version, if your platform can't represent - * int32_t, int16_t and int8_t, it just dumps out with a compiler - * error. - * - * 6) 64 bit integers may or may not be defined. Test for their - * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX. - * Note that this is different from the C99 specification which - * requires the existence of 64 bit support in the compiler. If - * this is not defined for your platform, yet it is capable of - * dealing with 64 bits then it is because this file has not yet - * been extended to cover all of your system's capabilities. - * - * 7) (u)intptr_t may or may not be defined. Test for its presence - * with the test: #ifdef PTRDIFF_MAX. If this is not defined - * for your platform, then it is because this file has not yet - * been extended to cover all of your system's capabilities, not - * because its optional. - * - * 8) The following might not been defined even if your platform is - * capable of defining it: - * - * WCHAR_MIN - * WCHAR_MAX - * (u)int64_t - * PTRDIFF_MIN - * PTRDIFF_MAX - * (u)intptr_t - * - * 9) The following have not been defined: - * - * WINT_MIN - * WINT_MAX - * - * 10) The criteria for defining (u)int_least(*)_t isn't clear, - * except for systems which don't have a type that precisely - * defined 8, 16, or 32 bit types (which this include file does - * not support anyways). Default definitions have been given. - * - * 11) The criteria for defining (u)int_fast(*)_t isn't something I - * would trust to any particular compiler vendor or the ANSI C - * committee. It is well known that "compatible systems" are - * commonly created that have very different performance - * characteristics from the systems they are compatible with, - * especially those whose vendors make both the compiler and the - * system. Default definitions have been given, but its strongly - * recommended that users never use these definitions for any - * reason (they do *NOT* deliver any serious guarantee of - * improved performance -- not in this file, nor any vendor's - * stdint.h). - * - * 12) The following macros: - * - * PRINTF_INTMAX_MODIFIER - * PRINTF_INT64_MODIFIER - * PRINTF_INT32_MODIFIER - * PRINTF_INT16_MODIFIER - * PRINTF_LEAST64_MODIFIER - * PRINTF_LEAST32_MODIFIER - * PRINTF_LEAST16_MODIFIER - * PRINTF_INTPTR_MODIFIER - * - * are strings which have been defined as the modifiers required - * for the "d", "u" and "x" printf formats to correctly output - * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t, - * (u)least32_t, (u)least16_t and (u)intptr_t types respectively. - * PRINTF_INTPTR_MODIFIER is not defined for some systems which - * provide their own stdint.h. PRINTF_INT64_MODIFIER is not - * defined if INT64_MAX is not defined. These are an extension - * beyond what C99 specifies must be in stdint.h. - * - * In addition, the following macros are defined: - * - * PRINTF_INTMAX_HEX_WIDTH - * PRINTF_INT64_HEX_WIDTH - * PRINTF_INT32_HEX_WIDTH - * PRINTF_INT16_HEX_WIDTH - * PRINTF_INT8_HEX_WIDTH - * PRINTF_INTMAX_DEC_WIDTH - * PRINTF_INT64_DEC_WIDTH - * PRINTF_INT32_DEC_WIDTH - * PRINTF_INT16_DEC_WIDTH - * PRINTF_UINT8_DEC_WIDTH - * PRINTF_UINTMAX_DEC_WIDTH - * PRINTF_UINT64_DEC_WIDTH - * PRINTF_UINT32_DEC_WIDTH - * PRINTF_UINT16_DEC_WIDTH - * PRINTF_UINT8_DEC_WIDTH - * - * Which specifies the maximum number of characters required to - * print the number of that type in either hexadecimal or decimal. - * These are an extension beyond what C99 specifies must be in - * stdint.h. - * - * Compilers tested (all with 0 warnings at their highest respective - * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32 - * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio - * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3 - * - * This file should be considered a work in progress.

This is - * a very useful and long desired include file which contains several - * very precise definitions for integer scalar types that is critically - * important for making several classes of applications portable - * including cryptography, hashing, variable length integer libraries - * and so on. But for most developers its likely useful just for - * programming sanity. - * - * The problem is that some compiler vendors chose to ignore the C99 - * standard and some older compilers have no opportunity to be updated. - * Because of this situation, simply including stdint.h in your code - * makes it unportable. - * - * So that's what this file is all about. It's an attempt to build a - * single universal include file that works on as many platforms as - * possible to deliver what stdint.h is supposed to. Even compilers - * that already come with stdint.h can use this file instead without - * any loss of functionality. A few things that should be noted about - * this file: - * - * 1) It is not guaranteed to be portable and/or present an identical - * interface on all platforms. The extreme variability of the - * ANSI C standard makes this an impossibility right from the - * very get go. Its really only meant to be useful for the vast - * majority of platforms that possess the capability of - * implementing usefully and precisely defined, standard sized - * integer scalars. Systems which are not intrinsically 2s - * complement may produce invalid constants. - * - * 2) There is an unavoidable use of non-reserved symbols. - * - * 3) Other standard include files are invoked. - * - * 4) This file may come in conflict with future platforms that do - * include stdint.h. The hope is that one or the other can be - * used with no real difference. - * - * 5) In the current version, if your platform can't represent - * int32_t, int16_t and int8_t, it just dumps out with a compiler - * error. - * - * 6) 64 bit integers may or may not be defined. Test for their - * presence with the test: #ifdef INT64_MAX or #ifdef UINT64_MAX. - * Note that this is different from the C99 specification which - * requires the existence of 64 bit support in the compiler. If - * this is not defined for your platform, yet it is capable of - * dealing with 64 bits then it is because this file has not yet - * been extended to cover all of your system's capabilities. - * - * 7) (u)intptr_t may or may not be defined. Test for its presence - * with the test: #ifdef PTRDIFF_MAX. If this is not defined - * for your platform, then it is because this file has not yet - * been extended to cover all of your system's capabilities, not - * because its optional. - * - * 8) The following might not been defined even if your platform is - * capable of defining it: - * - * WCHAR_MIN - * WCHAR_MAX - * (u)int64_t - * PTRDIFF_MIN - * PTRDIFF_MAX - * (u)intptr_t - * - * 9) The following have not been defined: - * - * WINT_MIN - * WINT_MAX - * - * 10) The criteria for defining (u)int_least(*)_t isn't clear, - * except for systems which don't have a type that precisely - * defined 8, 16, or 32 bit types (which this include file does - * not support anyways). Default definitions have been given. - * - * 11) The criteria for defining (u)int_fast(*)_t isn't something I - * would trust to any particular compiler vendor or the ANSI C - * committee. It is well known that "compatible systems" are - * commonly created that have very different performance - * characteristics from the systems they are compatible with, - * especially those whose vendors make both the compiler and the - * system. Default definitions have been given, but its strongly - * recommended that users never use these definitions for any - * reason (they do *NOT* deliver any serious guarantee of - * improved performance -- not in this file, nor any vendor's - * stdint.h). - * - * 12) The following macros: - * - * PRINTF_INTMAX_MODIFIER - * PRINTF_INT64_MODIFIER - * PRINTF_INT32_MODIFIER - * PRINTF_INT16_MODIFIER - * PRINTF_LEAST64_MODIFIER - * PRINTF_LEAST32_MODIFIER - * PRINTF_LEAST16_MODIFIER - * PRINTF_INTPTR_MODIFIER - * - * are strings which have been defined as the modifiers required - * for the "d", "u" and "x" printf formats to correctly output - * (u)intmax_t, (u)int64_t, (u)int32_t, (u)int16_t, (u)least64_t, - * (u)least32_t, (u)least16_t and (u)intptr_t types respectively. - * PRINTF_INTPTR_MODIFIER is not defined for some systems which - * provide their own stdint.h. PRINTF_INT64_MODIFIER is not - * defined if INT64_MAX is not defined. These are an extension - * beyond what C99 specifies must be in stdint.h. - * - * In addition, the following macros are defined: - * - * PRINTF_INTMAX_HEX_WIDTH - * PRINTF_INT64_HEX_WIDTH - * PRINTF_INT32_HEX_WIDTH - * PRINTF_INT16_HEX_WIDTH - * PRINTF_INT8_HEX_WIDTH - * PRINTF_INTMAX_DEC_WIDTH - * PRINTF_INT64_DEC_WIDTH - * PRINTF_INT32_DEC_WIDTH - * PRINTF_INT16_DEC_WIDTH - * PRINTF_UINT8_DEC_WIDTH - * PRINTF_UINTMAX_DEC_WIDTH - * PRINTF_UINT64_DEC_WIDTH - * PRINTF_UINT32_DEC_WIDTH - * PRINTF_UINT16_DEC_WIDTH - * PRINTF_UINT8_DEC_WIDTH - * - * Which specifies the maximum number of characters required to - * print the number of that type in either hexadecimal or decimal. - * These are an extension beyond what C99 specifies must be in - * stdint.h. - * - * Compilers tested (all with 0 warnings at their highest respective - * settings): Borland Turbo C 2.0, WATCOM C/C++ 11.0 (16 bits and 32 - * bits), Microsoft Visual C++ 6.0 (32 bit), Microsoft Visual Studio - * .net (VC7), Intel C++ 4.0, GNU gcc v3.3.3 - * - * This file should be considered a work in progress.
