; PIC EXAMPLE PROGRAM: TABLE.SRC
; August 19, 1992
;
; This 44-word program is a simple PIC application that shows some useful
; routines.
; 7-segment display.
;
; As the program is written, it expects to run on a PIC16C54-RC/P.
; button connects RA0 to ground (don’t forget a pull-up resistor from RA0 to
; Vcc, perhaps 10K).
; port B (segment A to bit 0, segment B to bit 1, etc.).
; a 20 pF capacitor to ground and a 4.7K resistor to Vcc are connected to
; OSC1 (OSC2 is left open).
; power and ground are connected to Vdd and Vss, respectively.
;
; Among other things, this program shows the following basic concepts:
;

; Set the device type, oscillator type, watchdog timer status, and code

When the button is pressed, the digit increments.
A 7-segment display (common cathode) is connected to
PIC16C54,RC_OSC,WDT_OFF,PROTECT_OFF
