Two receivers as input to different channels in iNAV

[gfalgiano]

In iNav, can I have input channels 1-4 on SBUS and additional channels coming from SRXL2 via UART? I'm working on an odd ball project and was wondering if this is possible.

I have a receiver that outputs PWM and SRXL2. I take the PWM signals (which contain stabilization from the receiver that I want to keep, hence the complication) feed that into a converter that then outputs SBUS and put that into iNav. That seems to be working for my intended purpose since I'm using iNav in manual mode and don't need iNav stabilization.

Now I need a couple more channels as inputs, but ran out of PWM outputs on the receiver. I have SRXL2 coming out of the receiver as well, but I only want to control a couple channels with this, not all channels, so I don't lose the stabilization coming from the PWM ports.

Alternatively, if anyone knows of an SRXL2 to PWM converter or some code to get that to run on a small board such as the RP2040, I can make that all work with the existing PWM to SBUS converter I'm using.

Any recommendations or solutions appreciated, thanks!

No. You can't pick and choose which channels to use from an srxl2 input and an Sbus input. You could override if one was using MSP.

You could introduce another mixing board, as you mentioned. You might also think again about the stabilization - INAV potentially has more information to draw from in order to do it better, along with having FAR more flexibility for you to configure it as you wish, with several different modes each having a large number of user-configurable options.
