    maximum voltage input for PIC16F877 ADC input..

    pic16f877a handling analog inputs i have set ADCON1=80H.. according to datasheet, this is to set all PORTA pins to analog input.. do i still have to find out the +Vref and -Vref? how am i going to do that? TQ.. :o

    maximum voltage input for PIC16F877 ADC input..

    adc input i have test out the ADC input with applying DC voltage from power supply. when i adjust around 2 volts.. all the output LED are light up.. is my testing on ADC input wrong? :( A problem i see from my testing is without supplying any voltage input to PA2, 2 LED are already light up..

    maximum voltage input for PIC16F877 ADC input..

    maxmimum pic adc input voltage i have connected the 8bit output of ADC to portD. by the time i input DC voltage around 1 to 2 volts, all the LED is light up.. is it the maximum voltage that supply to ADC is less than 2V?

    analogue voltage supplied to PIC.. Help!

    hi, im using ADC input of PIC16F874A microcontroller. My analugue input is around 10mV. can the PIC detect this small voltage? Or the voltage signal need to be amplified before input to PIC? TQ..
