DEMO1: PIC16F628-I/P CONTROL SOFTWARE

This is demo code, which allow control of the PIC-IO inputs/outputs via PC

with Hyper terminal.

Connect PIC-IO RS232 with cable to your PC and run Hyper terminal with

these settings: 9600,8,N,1,NONE. When you apply power this will be seen

on the Hyper terminal window:

***************************

* PIC-IO CONTROL *

***************************

To read the inputs in binary format type “r”, PIC-IO will respond with

something like:

%0000 if all inputs are 0 or

%1111 if all inputs are 1 (i.e. +5V is applied)

the inputs are with right less significant bit i.e. the order is: I4 I3 I2 I1

To read the inputs in HEX format type “R”, PIC-IO will respond with

something like:

$0 if all inputs are 0 or

$F if all inputs are 1

To change the outputs type “w0101”, this will switch on relay 1 and relay 3

and will switch off relay 2 and relay 4.

If you want to use HEX value you can write “W5” for instance which will

switch on relay 4 and relay 1 and will switch off relay 2 and relay 3.

Any other commands will not be recognized and PIC-IO will respond with

“ERR”
