CAN Test Rig

About

A set of test rigs for monitoring and creating CAN bus traffic using an STM32 F746ZG.

Usage

The following test rigs are currently available:

Name	Purpose
Listener	Receive and print specific messages on a CAN bus

Refer to the linked instructions for usage information.

Building

You will need the GNU ARM Embedded toolchain and make on your path. To build, run:

make -s

Add -j $(nproc) for a parallelised build.

Flashing

You will need the STLink toolset on your path. To flash, run:

make flash -s

Creating New Test Rigs

• Each test rig is implemented in its own C and header files, usually as a thread.
• Tests are configured in the configuration header. All test options should be set here with #define and prefixed with CONFIG_.
• The configuration header includes an option to disable each test rig.
• The top level test rig instantiates all tests.
• New tests can use the RTCAN instances provided by the top level test rig to interface with the CAN buses.
• While calling printf() (configured to write to UART3), threads must lock the printf_mutex provided by the top level test rig. While printf() is by itself thread safe, this mutex prevents mixing of printed outputs from different threads.
