I used MPLAB IDE V8.92 to write a PIC16F684 control port program and found that when the RC0 port and the RC5 port are used together,
RC0 has no output, RC5 has normal output, and RC0 also has its own...
In order to extend the transmission distance, the DSP system we designed uses two 232/485 adapters between the upper and lower computers, and uses twisted pair cables to connect them. However, after t...
