PBP3 Compilation problem

[Darrel Taylor]

Great! Glad you got it working.


1) PBP3 and MicroCode Studio 5.0 install seperately from any previous versions of PBP. I actually have every version since 2.41 on my computer.
But it's difficult to switch to different versions in MPLAB. And Earlier versions of PBP need an earlier version of MPLAB (not fun).

If you were using MicroCode Studio, you could switch between the versions easily from a drop-down box.

2) There's no reason why you can't use 2 analog inputs to the ADC.
Just set the ADC defines, and use ADCIN.

Thanks Darell. While I have your attention, could you please have a quick glimpse and advise me of my mistake as I am struggling with it from last many days. My code only Debugs "TIME=0 & AMBIENT=0". The voltage on both Pins is set to 2.5volts, but I am not understanding why it is outputting 0 all the time.

Got it. Found my mistake. The program is working fine now. Just realized that, it can't be aliases but need to be channel number at the ADCIN.
