Re: prius gen2 mg1 + leaf invertor gen2 + honda ima
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:-)

Re: prius gen2 mg1 + leaf invertor gen2 + honda ima
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 Invertor...

Re: Testing Newly Soldered v3.0 Board
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...

Re: Testing Newly Soldered v3.0 Board
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: pa5adc5.png The chart shows that at the input of the inverter, there is one more voltage divider an...

Re: Testing Newly Soldered v3.0 Board
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...
