A. Install GNU Arm Embedded Toolchain

Download the toolchain yourself from Arm GNU Toolchain Downloads according to your pc architecture, extract the files. Or use the provided link in the commands below

cd ~/Downloads
curl  https://developer.arm.com/-/media/Files/downloads/gnu/12.2.mpacbti-rel1/binrel/arm-gnu-toolchain-12.2.mpacbti-rel1-x86_64-arm-none-eabi.tar.xz -L -o arm-gnu-toolchain-12.2.mpacbti-rel1-x86_64-arm-none-eabi.tar.xz
tar xvf arm-gnu-toolchain-12.2.mpacbti-rel1-x86_64-arm-none-eabi.tar.xz
sudo mkdir -p /opt/gcc-arm 
cd /opt/gcc-arm/
sudo mv ~/Downloads/arm-gnu-toolchain-12.2.mpacbti-rel1-x86_64-arm-none-eabi/ .
sudo chown -R root:root arm-gnu-toolchain-12.2.mpacbti-rel1-x86_64-arm-none-eabi/

Build

# clean source code
make clean
# build
make
# or make with verbose output
V=1 make

B. Install Keil μVision (Windows)

Download Keil μVision from here https://www.keil.com/demo/eval/arm.htm

1: Install Keil μVision 2: Ignore the package manager of keil, you dont need aditional packages 3: Ignore the One or more Device Family Pack Devices are not present 4: In project go to Options for target (Alt + F7) -> In the target window, switch the Arm compiler (V6.19 works) 5: Start the compiling by going to project -> build target (F7)

Flashing

Option #A: Install SEGGER J-Link

Download and install JLink from J-Link / J-Trace Downloads.

# installation command for .deb
sudo dpkg -i JLink_Linux_V770a_x86_64.deb

The default installation directory is /opt/SEGGER

Flash

make flash

Option #B: Install pyocd

pip install pyocd

This will install PyOCD into:

/home/[user]/.local/bin/pyocd
/home/[user]/.local/bin/pyocd-gdbserver
/home/[user]/.local/lib/python3.10/site-packages/pyocd-0.34.2.dist-info/*
/home/[user]/.local/lib/python3.10/site-packages/pyocd/*

.profile will take care of the PATH, run source ~/.profile to make pyocd command available

Flash

Run flash.bat or flash.sh from the repo

Building With Keil μVision (Windows)

TODO and/or in the works: Include Float package buzzer support (let the vesc controll the buzzer). Add a delay for switching the direction of the main lights. Add a fade / transition to the lights when switching direction.
