V1.3.2-Refrigetation-Firmware-JSON-tested-end-to-end

Version 1.3.2: 28/04/2024

• Devolved PrettyPrint JSON into its own function - only loaded into memory if selected as option
• removed ALL spaces from Non Pretty Print JSON Message
• Removed Single quote ' from JSON header & Footer
• Changed print JSON from println to print - does this print \r\n?
• Added print line after print JSON to print null char (\n) to test different options (\n worked!)

Sketch uses 50618 bytes (19%) of program storage space. Maximum is 253952 bytes.
Global variables use 6761 bytes (82%) of dynamic memory, leaving 1431 bytes for local variables. Maximum is 8192 bytes.

V1.3.1-Refrigeration-Firmware-Functional

Version 1.3.1: 28/04/2024

• Removed additional commas from JSON message - BUG FIX
• Changed double to single quotes to wrap JSON
• rebooting error detected - stackoverflow?
• Reduced size of JSON buffer from 720 to 620
• Fixed rebooting error but check for problem reappearing
• #TODO: If rebooting issue or stackoverflow reappears: devolve pretty print JSON into own function & only load into memory if option is selected

Sketch uses 50780 bytes (19%) of program storage space. Maximum is 253952 bytes.
Global variables use 6921 bytes (84%) of dynamic memory, leaving 1271 bytes for local variables. Maximum is 8192 bytes.

V1.2.1-refrigeration-arduino-firmware-JSON-safe-output

Version 1.2.1: 20/04/2024

• JSONised all error & status messages
  // {"status":" JSON Status header
  // {"error":" JSON Error header
  // "} JSON status/error footer

Program Size when compiled for AtMega2560

Sketch uses 50682 bytes (19%) of program storage space. Maximum is 253952 bytes.

V1.1.1-refrigeration-arduino-firmware-tested

Version 1.1.1: 15/02/2024

• Added i2c Functionality.
• Added BME280: Atmospheric Temperature, Pressure & Humidity sensor.
• Analog sensor values fixed.
• Added quick start mode for V1 and fans.
• Tidied up sensor objects.
• Fully Tested and Validated with Hardware Rig.
• Changed naming convention from DAC (Data Aquisition Controller) to ADC (Analog to Digital Converter) to better represent the function of class methods.
• Devolved functions from .ino file into organised pages for readability

Program Size when compiled for AtMega2560:

Sketch uses 50794 bytes (20%) of program storage space. Maximum is 253952 bytes.

V1.0.0-arduino-controller-functional

Experiment now functional using Arduino as controller for Advantech Data Aquisiton Modules (ADAM) industrial IO modules.

• State machine controlled via JSON messages over serial USB connection.
• Full manual control of all outputs
• All previously existing sensors aquired and reported over serial JSON interface

Basic CLI Interface

Ability to run all equipment on experiment with Command Line Interface using Python3
Data Reporting via a separate websocket client.
