ATOM_CAN build fails for M5AtomS3
This repo is linked on https://docs.m5stack.com/en/atom/Atomic%20CAN%20Base which also has pin definitions for M5AtomS3 which implies that the ATOM_CAN example should work for M5AtomS3, but already building fails:

Can you provide your program, this will help me locate the problem better.
This is not my program, but yours: In the Arduino IDE just go to the menu File/Examples/M5Atom/ATOM_BASE/ATOM_CAN and try to build it for M5AtomS3
Might be a good idea to link to https://github.com/m5stack/M5AtomS3/tree/main/examples/Unit/MiniCAN_TJA1051T on the website. And also correct the table https://static-cdn.m5stack.com/resource/docs/products/atom/Atomic%20CAN%20Base/pinMap-34359801-b635-49e7-8b00-61bf09e7b4d1.png "ATOM LITE" is two times in there and AtomS3Lite is missing.
You can try this example
