Paul & Sabrina's cheap DIY 144v motor controller

[MPaulHolmes]

I think I forgot to mention b- on controller goes to b- on battery pack and also to motor-. Did you do that? And then b+ on controller to b+ on battery pack and motor+ on controller (all 3) to motor + on motor.

Hi Paul
Should I have changed the "C" file - I just changed the Hex file for the one you e-mailed not the other two

yes
Three motor +ve to my reversing contactor

Battery minus to the motor and the controller
Battery +ve to the controller

Yes - I was worried that I had done it wrong so I put it back in to check it
just now

The check confirmed the same problem

Can I check the parameters using the serial port??
Or using the PiCkit??

[MPaulHolmes]

No you just need the hex file. I'm at the store, but will check the code for my boo boo as soon as I get home.

Yes, you can check with the serial port. Type

config

That should show the current settings.

Hi Paul
RTD - config did not work

I went back to the PiCkit
This time I imported your file -
Hex file loaded successfully - great - I thought I was finished
Then I hit the "Connect" button
All sorts of things started happening

I think I had only put the new hex file into the PiCkit

Now I may have put it into the controller

Back to shed - to put it back in the car

Ok
put it back in - no change
So its back here next to the computer again
I will see if I can get RTD to work

I'm trying to program at the moment, but my wife has a very thorough story at the same time (as I type). I hope she doesn't read this. haha. So, I won't be able to concentrate until the story is over.

edit: story done! Let the debugging begin!

edit2: story starting again.

"Can you take out all the garbage." yes. OK now I'm ready to start.

I have only a couple of questions, the WHAT is connected to the What" mosfet, MLCC OH BOooy, seriously I admire anybody that understands all of this. I cAN only assume that I would electrocute myself and or start an electrical fire if I tried to duplicate any of this technology. But seriously guys/girls, WOW I feel so uninformed and uneducated in the field of electronics--Good Work!!!

[MPaulHolmes]

hahaha. I know! It took a year or 2 before any of it started making any sense.

Hi Paul
I can get the PiCkit thing to respond
but when I hit "verify" it comes back with an error message
Can't get RTD to see the thing at all
