This repository contains all the source code for the SAMD21G18 ARM Cortex MCU on the CANZERO
arduino-package contains the source code for the Arduino package needed to user NoCAN in the arduino IDE.
bootloader contains the SAMD21G18 bootloader for NoCAN.
default-application contains the default application that ships with a new CANZERO board on the SAMD21G18.
lib contains common libraries (SPI communications with the STM#@ driver IC).
Compilation relies on the the arm-none-eabi-gcc toolchain and make.
Compiling the firmware requires the very small subset of CMSIS libraries that come with ATMEL ASF 3. The code itself does not use ASF but relies on direct programming of SAMD21G18 registers.
To compile the code, you will need to edit the ASF_ROOT variable in the Makefile to point to the location of your copy of the ASF.
