This is demo code which blinks the LED on PIC-P18 board.
Note:
This is demo code which show how to read BUTTON status and to switch
the LED ON when button is pressed and LED off when the button is
depressed.
This is demo code, which show how to use the USART to send and receive
characters from host PC via RS232 cable.
The MAX232 by default is not connected to PIC on the board so you have to
solder two wires – one from RB2 (pin #8) of PIC16F628 Tx signal to MAX232
Rx labeled pin, and second from RB1 (pin #7) of PIC16F628 Rx signal to
MAX232 Tx labeled pin.
IMPORTANT: as seen from the schematic RB2 is also connected to the
User button, this means if you press the button during the
communication the communication will be lost and you may burn your
PIC UART port!
You must program the HEX code to PIC16F628 and run the code.
If you programmed the PIC correctly and wired the UART, when you open
Hyperterminal on your host PC computer with 9600 bps, 8 data bit, 1 stop
bit, No flow control and apply power supply to the PIC-P18 every character
you type on the hyperterminal will be printed back with “*” i.e. if you type
“abc” you will receive “a*b*c*”.
