Hi,
I have updated my compiler by 3.191 version ( from 3.184 )
IDE 3.143
PCB,PCW,PCH 3.191
Windows XP Professional V.2002 S.P. 2
I can't configure my PIC16C781 for A/D module, because the
window is Blank ! The window has only two combobox to configure
Option button for A/D channel not exist
The PIC16c781 has 8 A/D channel
Can you help me?
Thank
G. |

I think they removed support for the A/D converter for the 16c781
in PCM vs. 3.191. You'll either have to upgrade the compiler or
setup the A/D configuration manually, with code.
For your information, here's the ASM code produced by version 3.212.
I haven't checked it, but assuming it's correct, you could use it as a
guide for writing your own A/D functions.

Thanks, but I have downloaded 3.212 version.
On-line there are two version 3.191 and 3.212, why? |

| 3.191 is the 'stable' version, while 3.212 is the latest (and beta) version. which may contain bugs. |
