The board has an Ethernet port and a serial port. The serial port is used for message communication and the Ethernet port is used for log output. printf outputs logs to the standard output device, but...
Correctly and simply speaking, we should use pointers to static class members instead of pointers to class members. As John_Lee's analysis of the two methods shows, the latter really makes a simple pr...
I set a power-off receiving interrupt, and I have been waiting for it since the program started. Unfortunately, it has never entered the interrupt. But the strange thing is that there are values in th...
