LPC43xx example projects

This repository contains some examples for the LPC43xx microcontroller. These projects are based on the blinky project covered by this blinky tutorial. The project folders also have a readme file.

For flashing you will need either:

• Black magic probe You can also turn a cheap bluepill board into a blackmagic probe if you already have another SWD programmer.
• FTDI based jtag/swd programmer such as JTAG-lock-pick Tiny 2

To build these examples you need the following software:

• CMake
• GNU Embedded Toolchain 7-2018-q2-update (arm-none-eabi-gcc)
• Git
• OpenOCD (if you don't use the Blackmagic probe)

Before building

Copy the config.cmake.example file as config.cmake from the repository root to the project folder you want to build. Uncomment and choose your desired optimization level (set(OPTIMIZE 0) for debugging). And enter the correct device file for your blackmagic probe.

Build the firmware the first time

Go into the project root (e.g. multiblinky) and create a directory 'build' and go into that directory

cd multiblinky
mkdir build
cd build

Then run cmake to fetch all dependencies and create the makefile. When that has successfully completed we can build the firmware by calling the Makefile.

cmake ..
make

If everything goes smoothly the tail of the output should look like this:

Scanning dependencies of target Multiblinky
[ 96%] Building C object CMakeFiles/Multiblinky.dir/src/board.c.obj
[ 98%] Building C object CMakeFiles/Multiblinky.dir/src/main.c.obj
[100%] Linking C executable Multiblinky
[100%] Built target Multiblinky
Scanning dependencies of target bin
[100%] Built target bin

and you should find a elf file and .bin file in your build directory. Ready to flash to the target microcontroller.

Run make flash to flash using the built in tools, or use your own method.
