I would like to ask you. After my program enters the CAN interrupt, I use CANIntStatus (CAN0_BASE, CANI_INT_STS_CAUSE) to read, but why does it always return "0"? I have read a lot of documents, and d...
[url] I am a beginner in M4 and want to create a new program by imitating the source program. I found that after setting various paths and predefined symbols, the compilation can pass, but the functio...
