; SAMPLE PROGRAM: BARGRAPH.SRC
;
; February 9, 1996
;
; This program uses a PIC16C74 to convert an analog value into a reading
; on an 8-segment LED bargraph.
; AN0 (pin 2) on the ’74.
; Port B (pin 33 is first LED, pin 34 is second LED, etc).
;
; The program is written to only light one LED at a time, but could easily
; be changed to light multiple LEDs (all LEDs up to the reading).
; only one LED on insures low current draw, which may be important if
; you’re powering the circuit with an emulator.
;
The following listing is the source code for the project. It’s contained in a file called
BARGRAPH.SRC, which is located in the APPS directory of the PIC Tools Diskette.
