Description: PIC microcontroller internal timer 0 as a 16-bit timer, and open the overflow interrupt. MCU external interrupt 0 pin is connected to switch SW2, and set to the falling edge of the trigger. The microcontroller UART interface operates in full-duplex asynchronous mode, one start bit, 8 data bits, 1 stop bit, baud rate of 9600, and open to receive interrupt communication with the PC. Write a program to achieve functional: SW2 button is pressed, the display on the LCD Timer0 Start " to, timer 0 start work, and then displayed on the LCD Timer0 Working" When UART receives commands sent to the PC, " P" , the timer 0 stop working, the Timer0 Stop " is displayed on the LCD, and the timing time is sent back to the PC. And to use ICD2 emulator for procedural programming and simulation debugging.
