It was a long time ago in a galaxy far, far away, I don't remember where I was able to get this firmware from. OK, we will search:-)

Now I see the problem. v3 Boards have a 5->3.3V divider on board on the current sensor input. So your 1.65V is divided again, therefor hicurofs
With the voltage you'd have to check the analog signal that goes into the V3 brainboard and how it behaves as you change HV


Thanks. Divider on the ...

Ok, i swaped resistors in the divider and now i have 1.2V at PA5, PB0 at the comparator inputs. Output of the comparator is 3.7V. But on the 3rd pin (PA3) NAND I have 0V. PA3 on the microcontroller in the test mode working as input or as output? If it's works as input, maybe i need connect SIG_MPROT ...

If you apply 5V as indicated on the test board, then the pins P5, P3, P4, P8 of the test board will be 5V*(10k /(47k+10k))=0.88V. But when we installed the inverter, then we get the following diagram:

The chart shows that at the input of the inverter, there is one more voltage divider ...

Thanks for the tip. I checked the test board, everything is fine. The resistors correspond to the nominal values, all the necessary pins are connected.
The inputs of the comparator 2901, have the following readings:
5 - 0.26v
4, 6 - 0.82v
7 - 0.26v
8 - 0.26v
9, 11 - 2.46v
10 - 0.26v
accordingly, the ...

Hi!
What is a Window Comparator and Inhibit Circuitry?

Hi,the new boards use a new SWD connector. What type of connector should I use?

Hello. What can be maximum eRPM? Are there any software or hardware limitations?
