Kicking the CAN #2 — Hello CAN

2026-03-05

First, I wanted to test whether the modules were working correctly with their controllers.

I created two projects, one for the STM32 and one for the RPi4. I chose C as the programming language for both Hello_CAN programs.

I instructed Claude Code in both projects to write a test program that verifies the functionality of the setup. In both projects, it suggested a loopback test, which Claude Code then implemented.

Test result: Everything works perfectly.

So far ... so bad.
