TIDA-00643 labs question

Shay Stockstad

I've completed the labs as outlined in the tiduak1 appnote and have obtained the offsets, Spd_kp, Spd_ki, overmodulation factor, and a more optimal Idq_kp than the auto-calculated value for my motor. The appnote goes so far as lab10a for overmodulation. What further labs do I need to run from here to make this a standalone controller?

you can start from whichever lab you like to build your own fully embedded project (that portion is up to you).

most common projects to start from would be 5a (torque), 5b (velocity), 10a (velocity + overmodulation)

Thanks Chris,

I'm nearly finished with this design but I'm stuck on the ecap setup of section 5.3 in tiduak1. I copied lab5b to a new project and added the hooks for the ecap as outlined in the guide. I have a 3.3V RC PWM input to control the design but when I hook this input up I see pin25 on my 28027 is pulled low. I must be missing something simple in the config somewhere, I've double-checked my setup against the guide numerous times but can't seem to find where the issue is. Any suggestions?

Nevermind my last question, I'm able to feed in the PWM signal into the ecap module now.
