Re: MSP commands

Hello,
there are quite some calculations and "bit flipping" done to get proper MSP command and is probably not feasible to do-it in TeraTerm and likes.
That said you can still look at http://www.multiwii.com/wiki/index.php? ... l_Protocol.

Re: AfroMini32 PPM to Servo (Baseflight)?

Thank you Patrik.
I actually wanted to use simple PPM to PWM option due its basic simplicity of haveing all the settings in TX (and receiver far from other components).
But I'll do cmix if other options are off.
How to disable/enable ONLY_ARM_WHEN_FLAT option in BF.

AfroMini32 PPM to Servo (Baseflight)?

I'm trying to use AfroMini as simple PPM to PWM converter, but after switching to that mode nothing works.
I can see RX PPM input in GUI but nothing gets to servos (except 400Hz midpoint).

Any tips how to set this up!

Wrong default mix for quadx and + on AfroMini32

Hello,
today I put (freshly flashed/updated) AfroMini32 on miniquadX and after selecting quadX (or +) in configurator I get no output on S3 and S4 (motors don't spin at all).
I had to mirror outputs from motor 3 and 4 to motors 5 and 6 using cmix to get it working.
