Tuya CBU bk7231N and bp5758d

Open abenne62 opened this issue 6 months ago • 4 comments

hello, I have some feit electric smart bulbs from walmart (om60/rgbcw/ca/ag/3 N) that I'm trying to get switched over to openbeken. Some of the bulbs I ordered a few years ago have the bk7231N directly on the board, and flashed via wire just fine and work perfectly with the pins set. A set that were bought more recently have the tuya CBU board in them, which are still interfaced with the bp5758d like before. I also got openbeken flashed just fine, but no combination of gpio settings is making the leds power on. I have double checked the pinouts on the board and still am getting nothing. any thoughts? thanks

pinout:

tuya CBU pin 11 --> BP5758 SCL tuya CBU pin 12 --> BP5758 SDA

BP5758 out1 --> blue led BP5758 out2 --> red led BP5758 out3 --> green led BP5758 out4 --> C BP5758 out5 --> W

CBU doesn't have P12 routed out. do you mean to have set P24/P26?
