"89s51" When I made a simple circuit board, the microcontroller did not work. My program was that P0 P1 P2 P3 changed from 1 to 0 in a cycle of 2s, but there was no response. What's the problem? The c...
The board is very exquisite, but I don't know why the serial port doesn't respond after I power it on. There is only one output, and then there is no response! ! It seems that I will try to upgrade th...
