Thanks for clearing it up, Russ. I think I won't bother adding any external circuitry for my own project (a no frills 8 channel volume control).

So on the outside chance someone might be able to help me I thought I'd take a shot and ask.

I bought a Kook kit last year and for various reasons just got around putting it together and can't get it to work. I then read that some of the PICs were inadvertantly shipped without being programmed. How do I figure out if this is the problem? If it is, I how do I go about getting it programmed? Before someone suggest I e-mail Russ..let me say I did and am still waiting for a reply.

Thx

Mike

Hi Mike-

I have tried emailing you three times but the emails get bounced. Is your mailbox full?

I am willing to take a look at your Kook if it needs it. It does nothing when you power it up?

Hi Brian! I appreciate the quick reply. I just registered on the Twisted Pear site an it replied to my e-mail address so I don't know why you can't get through.

Pls make sure your typing metzlerm1@comcast.net not .COM.

Anyway I haven't taken any pics yet but I'll take some and e-mail to you if you'd like or post them which do you prefer?

Thx again

Mike

Hi,

when I try to compile the C code with Hitech PCCC, it shows the following error:

Executing: "C:\HT-PIC\BIN\PICC.EXE" -C -E"pga2311.cce" "pga2311.c" -O"pga2311.obj" -Zg9 -O -ASMLIST -Q -MPLAB -12F683
Error[000] D:\pga2311\pga2311.c 72 : undefined identifier: TRIS1
Error[000] D:\pga2311\pga2311.c 73 : undefined identifier: TRIS2
Error[000] D:\pga2311\pga2311.c 74 : undefined identifier: TRIS3

Error[000] D:\pga2311\pga2311.c 76 : undefined identifier: TRIS5

How can I define the TRIS1-5?
Actually, what TRIS1-5 are?

Thanks a lot.
