Overview:
The code in this directory was used to drive a demo board that I made
for a UOC demonstration day.
The demo board consisted of 5 240V 3A solid state relays, a RS-232 port,
a 1-wire interface port (using a RJ-11/12 connector), and a number of LEDs.

Following is a list of the files and what I can remember about them.....
... it has been a while.

This is a full res jpeg image of the schematic for the demo board

***************************  LIGHT1.C ********************************
USES: delay.h, delay.c

DESCRIPTION:
Just flashes the LED's on the demo board.
Does a bit shift to right on PORTA and PORTB then does some binary
counting of sorts, and goes back to the beginning.


*************************** SERIAL.C *********************************
A version of the HT-PIC C Serial driver that I modified to try to get
it to work with the 16C84 - I can't remember if I succeded.

*************************** INT232.C *********************************
An Interrupt and timer driven RS-232 driver that I wrote for the 16x84
As far as I can remember - it worked, but don't quote me on that.
I have not actually used it for a while.
Has getch and putch commands.

*************************** DEMO2.C **********************************
USES: delay.h, delay.c, serial_s.c, 1wire002.c

DESCRIPTION:
Demo2.c is the program that ran at the demo day. It was really simple
and controlled a Perastaltic pump but using 2 i/o pins, read the
temperature on a temperature sensor that was mounted above a light bulb
and turned the light bulb on an off. It was connected to a dumb terminal
that just displayed what was happeing and the current temperature of the
probe.


*************************** DEMO1.C **********************************
USES: delay.h, delay.c, serial_s.c, 1wire002.c

DESCRIPTION:
The first version of the demo program - think I had some problems that
were ironed out in the second version.


*************************** DELAY.C *********************************
The delay routine that came with the HT-PIC C compiler

*************************** BASIC.C *********************************
USES: always.h,int232.c,commands.h

DESCRIPTION:
A simple program to test the interrupt driven serial routines I wrote.
Note that I used Shane Tolmies "always.h"


*************************** 1WIRE002.C ******************************
USES: M_DELAY.H

DESCRIPTION:
Routines for driving the Dallas 1-wire bus.
Wrote these routines from scratch cause I got fed up with the stuff
provided by others that didn't work.
These are crude, but have worked well in many situations.


*************************** _DELAY.C ******************************
Delay routines using shanes always.h  and the std delay.h files
Cant remember this file at all!!

*************************** DEMOBRD.S01 ***************************
*************************** DEMOBRD.PCB ***************************

Protel schematic and pcb files.  These were created using the old
dos version of Protel, they can be imported into the latest versions.
