Hi all, Now I trying to get sampling and I get the some values expected. Without grounded, I got some values like 03f or sometimes,01fc like that even i didn't feed any analog value. When I connected ...

Sorry PCM programmer,
I wrongly posted yesterday. Actually I used pin 4 and 5 (using AN2 and AN3 for Vref + and -.
#define AN0_AN1_VREF_VREF 0x0D // A0 A1 VRefh=A3 VRefl=A2
Could you p ...

Hi Ttelmah,
Sorry, I forgot to say clk freq. My one is 20MHz and I tried to use one or two channels. I saw some examples programs written by PWM programmer and tried with these. But ...

Hi all,
Anybody will help me to get the example program for ADC conversion. I want to convert from 2V analog data to 10 bit digital value. My PIC is 16F877A. Thanks a lot!!! Acutally I don't ...
