Hello, I apologize for the long answer was busy) To start, you need to unsolder pin 6 of the MCP4728 microcircuit and apply voltage to the PCB pin from 0 to 4 volts (current) Attention, take the ground from the MCP4728.Clanarn wrote: ↑Sun Jan 24, 2021 8:31 amHi! I have been trying to get my gen2 obc/pdm working using svizpdm method without any success yet. The dc/dc works by only supplying 12v+ to pin 16 and 18 on connector B24.
Ive followed the instructions and got the AC relay to close. The pwm on pin 18 on UCC2895 won't start from grounding the component seen in step 4. UCC2895 pin 20 shows 4.5v. Analog signal is supplied to the MCP4728 with a potentiometer. Is there something else that has to be connected or modified to make this work?
There is a working version of control via the CAN bus) My friend Taras from Ukraine did it and uses it safely. I will ask him to share))) Good luck to everyone and large capacity in your batteries))))
