Any possibility of a way to get signal to the PB to use as a turn signal feature? I use PB on all my headlight builts and would be cool to have them flash amber for turn signals
I think it should be possible to use GPIO with an appropriate voltage divider to detect the turn signal lamp voltage. See this post from earlier.
Would this augment the stock turn signals, or replace them?
The challenge might be that if you don’t like the car’s default timing for the flash, your options get complicated: you could cancel the signal after not detecting an expected next flash, but that might be late. I don’t know if turn signal commands are sent over the CANBUS and it’s worth trying to read those; or install a supplemental switch somehow, perhaps physically detect the turn signal lever’s position.
