FrSky 24ch parser

[rostal]

Hello. Is there any hint how to parse more than 16 channels of SBUS protocol? My DIY drone is based on STM32.

STM32 is a reference to the size of the bite. It uses a 32 bit processor.

I think most FrSky TX output 24 Sbus channels. If you need more than that I think you can dual transmit the additional channels with a second TX RF module.

Right. 22 bytes and 23rd byte with bit fields to parse. But I don't get it because some bits are FAILSAFE data. So only 6 bits to parse for 0/1 values

That’s the point the processor has nothing to do with the S-bus channel availability.

Are you transmitting the channels you want?

Your drone needs more than 16 channels?
