    Hi ! My G27 board is dead (I accidentaly inverted the +/- from power supply...). Now I am trying to replace the board with MMOS feedback + stm32F4 + moto monster.

    What I need it to get informations from the G27 encoder. I know how works a classic 4 wires encoder. You get power from red and black wires, and digital signal from the two other cables.

    But the G27 has 5 wires ! I guess black and red are power supply (5V between both), but I don't know for the others... I got also around 5V between red and green.

    It's possible that the encoder suffered when I plugged the inverted power supply, but I made tests on an other working G27 and didn't manage to find out how the encoder works...

    Thanks in advance for your help ! 34023187051_cacf67d3f9_b.jpg

    Thanks ! So I guess mine is broken because the best I can do is to have one channel working...
