Kicking the CAN #0 — About
2026-03-05
After Watasoge, I carried out the next experiment in Agent Driven Development.
In my CE studies, the CAN bus system was introduced on a single lecture slide. My knowledge of CAN was therefore limited to less than the content of that slide. CAN exists, it is used in automobiles, it has two data lines and no clock and no CS.
In my experimental setup, a Raspberry Pi 4 and a NUCLEO-G431KB were supposed to communicate with each other via CAN. After a chat with Sonnet 4.6, I ordered a VP230 breakout board for the STM32 and an MCP2518FD breakout board for the Raspi.
