Re: Solar car races

Awesome projects guys!

I am making a high voltage controller too, will be releasing it shortly, next few days.
Are all components Q-100?

Re: Moving around pins on the STM32 and upgrading to f7 over f4

I decided that having power management on-board will be easier in the long run if I can fit it so I have been taking care of that the last few days. All components up to this point are Q100 with the exception of the 12v to 5v DC-DC: MTC1S1205MC-R7. My three questions are: 1. can I use a non-isolated...

Re: Moving around pins on the STM32 and upgrading to f7 over f4

Awesome! Looking forward to the new software!

I just noticed that I was powering the new CAN transceiver I picked out with 5V.

Just a minor update I went back to the 64 pin F4. I'm going to keep this as simple as possible to start.

Re: Moving around pins on the STM32 and upgrading to f7 over f4

PD10 is not an analog input :lol: :lol: :lol: I'm sorry dude, no wonder I look like a scrublord. The non-essential components to getting the VESC up and running were thrown on random pins, I was going to go back and fix all that. My apologies for not mentioning that. From now on I'll just leave por...

Re: Moving around pins on the STM32 and upgrading to f7 over f4

Simply stating I did not fix all the problems is more than enough for me! :D I will re-read all the posts more thoroughly. Thank you for reviewing older issues! There were some things that went way over my head in this thread...... I think I should stick with the same exact F4 based processor and ma...

Re: Moving around pins on the STM32 and upgrading to f7 over f4

No DRV, gate drivers! The whole objective of this project is to make a high voltage/amperage controller. Upgrading the processor would just be icing on the cake.

I think I am done! Anyone see anything wrong?

Re: Moving around pins on the STM32 and upgrading to f7 over f4

Current sense will output a 2.5V +- current signal so it will go above the max 3.3V ADC input. You should use the birectional current sense not the U version. Eric If I use the bidirectional one, I will not get the bottom half of the sine wave on the ADC pin, and will need a diode to protect the AD...
