Pid Algorithm with Picbasic

[Desperate]

Hi Everyone..
I want to control an ac motor driver with PID algorithm. The driver needs 0-10V contol voltage. I get the control voltage by an 8bit DAC that is conneted to one of the ports of 16f877. I use a takogenerator for feedback. The problem is that : I couldn't succeed writing the codes in PBP. Can anyone help me about that or send me the picbasic codes of a similar PID project? Thanks...

You can find PID example code in the Industrial Controls Tutorial from Parallax

Really useful code examples for PID on www.jashaw.com. Buy his book too.

Update:

I sit in the Who's Online page a lot, and I keep seeing people reading this thread ...

So I just wanted to say that about 3 years later HenrikOlsson posted a nice implementation of the Parallax PID routines for PicBasic Pro.

PID-filter routine (2nd try).
