Hi guys, still working on it, trying to make things go. I'll just put it out there for everyone to see. Just in case others run into the things I have when building a controller.

I have not been able to get Realterm to work because of the com port issues. I have a PCMCIA adapter coming but that's a few days away. While I was waiting I tried the USB again and have some success communicating.

After trial and frustration I can use RTD explorer on Comport23. Go figure.

I have changed the PC-time to 040, and the contractor closes.

Still no go.

I went back and reread the thread from about page 150 and have since checked to see if the rise rate is set to 006, and it is.

Watching RTD with throttle, PWM, and DEBUG graphed it looks like everything is following correctly as the throttle input increases the PWM is right there with it.

So, am I seeing the control section functioning properly up to firing the FETS?

The next place I am going to look is for the signal to and from "U7".

Oh,the LEDs are solid, the motor connections have been double checked. Volts are at the controller at B+. This is only a 12V test to see that everything is functioning properly.

I sure hope I didn't miss something simple.

Fire away!!!
