Source Code – PIC16C54
The tutorial program listed below is for the PIC16C54 device. It can be
modified for all other supported devices. See files titled tut??.asm , where
?? represents the last two numbers of a device.

This program runs on the PICDEM-1 demo board.
In the Demo board, Port B is connected to 8 LEDs.
RA1 is connected to a switch (S3). This program increments
the file register count each time S3 is pressed.
The value of count is displayed on the LEDs connected
to Port B.
Net result is that Leds should increment in a binary
manner every time S3 is pressed.
