Paul & Sabrina's cheap DIY 144v motor controller

So I have a logic analyser.. and I'm looking at this HIN202 diagram.. but I'm confused on were I should be able to pickup ttl uart on that chip.. and gnd..

Is there a schema available? that would help.

[flores]

I'm guessing it must be 12 & 11 and 15 for GND

I'm catching my input at ttl level on pin 12, but there is no response on 11:

Just because it looks cool, my setup:

Yep, that's right. I'm trying to find my serial to usb connector at the moment, and then I'll check the serial. I've tested the serial, and then I made a bunch of changes for actually using it in the golf cart, and I need to see if I disabled some serial comm from the micro. I was testing each part separately before. Well, the search for my cable now continues. I don't think I have the commands echoing to the screen. Let me see what is going on. I'll be back soon.

Paul, could it not work because all my inputs are disconnected?

[flores]

Just tested if it gives something on boot.. but nothing

[MPaulHolmes]

aha!!! Yes. It's not getting to the serial communications code, because there is no throttle present, so it's just freezing until a valid throttle is present. You shouldn't need any other inputs connected.

[flores]

Check!

Connected the throttle wires together.. and now I hear the relays..
And on boot it says:

The Stinky Diaper firmware, ver. 1.0

But it still does not respond to the config command, should it?

[MPaulHolmes]

I'm checking now. Well, in like 5 minutes, because this laptop doesn't have realterm on it, and I must download it.
