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...

The relationship between the diskless client's memory and the server's disk image file is established, but how do they correspond, what is the format, and how are they not limited by the size of physi...
In the past, I played with 51 and AVR. The low power consumption of 430 has always been a legend.
I participated in the recent group purchase of LaunchPad. After testing it, I was full of praise for t...
