SOFTWARE:

DEMO1:

PIC16F876-I/P

BLINK LED

This is demo code which blinks the LED on PIC-P28 board.

Note:

LED jumper should be closed!

DEMO2:

PIC16F876-I/P

BUTTON read

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.

DEMO3:

PIC16F876-I/P

RS232 send / receive routines

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 RC6 (pin #17) of PIC16F876 Tx signal to

MAX232 Rx labeled pin, and second from RC7 (pin #18) of PIC16F876 Rx

signal to MAX232 Tx labeled pin.

You must program the HEX code to PIC16F876 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-P28 every character

you type on the hyperterminal will be printed back with “*” i.e. if you type

“abc” you will receive “a*b*c*”.
