18F2550 20mhz HSPLL set up for USB
PIC functions and pcb is fine. I can get a simple blinky light to work. I can get a correct ADC value to write to EEPROM and read through the programmer, but I cant get it compare the ADC value with the value stored in fb and turn on or off the LED as I vary the voltage in the ACD pin.
What the heck am I missing?
define OSC 48
DEFINE ADC_BITS 10
DEFINE ADC_CLOCK 3
DEFINE ADC_SAMPLEUS 50
raw var word
raw1 var word
fb var word
fb = 205
ADCON1 = 001011
ADCON2 = 000011
TRISA = 001111
TRISB = 110000
TRISC = 000000
PORTC.2 = 0
main:
pause 100
adcin 0, raw
raw1 = raw/10
if raw1 => fb then
Portc.0 = 1
else
portc.0 = 0
endif
goto main]
