PIC16F877A serial port transmission

PIC16F877A serial port sending and querying methods. It took me a day to find out this. It turned out to be a problem with the serial port chip voltage. The summary is as follows: 1. Pay attention to the power supply voltage of the 232 serial port chip, there are 5V and 3.3V 2. Pay attention to the TXD and RXD wirin

C51中断（void timer1(void) interrupt 3 using 3）

interrupt indicates the interrupt priority, and using indicates the working register group used. interrupt x using y The xx value after interrupt is the interrupt number, that is, which interrupt port this function corresponds to. Generally in 51, 0 is external interrupt 0 1 is timer 0 2
