Hi everybody !
I intend to use ADC(AN3) of 12F675 and using VRef . My question is : pin 6-GP1 must be connected to VDD ?
I post my code. Thanks in advance !
Code:
@ DEVICE PIC12F675, intrc_osc_noclkout, wdt_off, pwrt_on, mclr_off, bod_off
DEFINE OSC 4
DEFINE ADC_BITS 10
DEFINE ADC_CLOCK 3
DEFINE ADC_SAMPLEUS 50
CMCON = 7
OPTION_REG = %10000110
TRISIO = %00011110 'if 1 then GPIO=input ; if 0 then GPIO=output
ANSEL = %00011000
ADCON0 = %10001101
..............
adcin 3, read_volt
read_volt=read_voltage * 5000
read_volt=div32 1023
