Does this mean BDShot can only be used on S1, S4, S6, S7?
It’s not obvious to me because before I discovered this file I had BDSHOT on S1-4. Of course S3 didn’t work, but I could get telemetry on the rest, including S2.
Truth is I don’t actually know what BIDIR
means in this file or if it has anything to do with BDShot. Can’t find any docs on it and I wasn’t able to find in the source code where this file is interpreted either.
The other issue on my mind is that TIM8 and TIM1 are only connected to three pads. I can switch to S5+ on TIM2 but it’s not mentioned in DMA_PRIORITY
? I also have no idea what the implications are for BDShot or motor control but I’m wondering if anyone knows if using TIM2 for one or two of my motors will cause problems.
