Programming PIC Microcontrollers in BASIC - mikroElektronika

Potentiometer gives 0V in one terminal position and 5V in the other – since we use 8-bit conversion, our digitalized

voltage can have 256 steps. The following program reads voltage on RA0 pin and displays it on port B diodes. If not one

diode is on, result is zero and if all of diodes are on, result is 255.

program ADC_8

main:

TRISA = %111111 ' Port A is input

PORTD = 0

TRISD = %00000000

ADCON1 = %1000010 ' Port A is in analog mode,

' 0 and 5V are referent voltage values,

' and the result is aligned right

' (higher 6 bits of ADRESH are zero).

ADCON0 = %11010001 ' ADC clock is generated by internal RC
