multiple ADC using DSpic 30f3010

[angeline]

I am trying to convert two analogue signal using pin AN2 and AN3 by the dspic30f3010. However , I dont really understand how the result is stored. Therefore, I have written a code to test on LED first . If the input voltage in AN2 is above 2.5V, the LED in port E will light up . I assume for this AN2 conversion result is stored in ADCBUF0. SAme goes to AN3 where the LED in port D will light up from the ADCBUF1. However , my code doesnt work .
I think I do not understand how the result is stored. Below is my code , I wish to get some advice . Thanks for your help .

K,
Point 1 - PicBasicPro this code is not...
Point 2 - PicBasicPro <> C
Point 3 - PicBasicPro doesn't support ANY of the dsPIC series MCUs.
Point 4 - If you get the above code to compile with PicBasicPro, I'll give up programming altogether and take up underwater basket weaving as a career.
Any questions?

Sorry I forgot to mention ... I am using MPLAB IDE to compile this and ICD 2 as the connector to program my dsPIC ...

Still doesn't look like that'll compile under MeLabs PicBasic or MeLabs PicBasicPro, which only support PIC12, PIC14, PIC16, PIC18xxxx devices.

Hi Angeline,

What Ski is trying to tell you is that we mostly discuss code written in BASIC in this forum. You might want to try here
http://forum.microchip.com/
for help with your C code.

Best of Luck,

You'd figure some folks could figure that bit out all by themselves...

Oh, now I understand . This is my first time posting . By the way, thanks =)
