VOXL 2 IO RC with RB5 Flight on recent VOXL SDK releases
-
From what I understand from the documentation, using a M0065 VOXL 2 IO board for SBUS RC input should be supported with VOXL SDK 1.0.1 and 1.1.0 (and also with 1.1.1 after an update of the M0065). However, our RB5 Flight on 1.1.0 was still not reading any RC channels after updating from 0.9.5.
I noticed in the
voxl-px4-startscript that the M00052/RB5 Flight board has a special case for getting RC input with Spektrum receiver from the apps processor, while other boards use the DSP. Meanwhile, thedsp_sbusdriver used for getting RC input from M0065 seems to be specifically for the DSP, and defaults to a port number 7, which seems to correspond to the VOXL2 RC interface, but not RB5 Flight. Adding an argument to change this to 13 didn't work for our RB5 Flight.This still seems to be case for the same script in SDK 1.1.1, where the new
voxl2_iodriver, while not noted to be DSP-specific, also specifies a 7.Is the combination of VOXL 2 IO (in any form) RC, VOXL SDK 1.1.0+, and RB5 Flight supposed to be supported? And if not, is support planned to be added in the future?

@dscott Unfortunately, we overlooked that particular configuration and it is not supported yet. We are looking at the best ways to support this configuration to try and get you something that you can use.

@Eric-Katzfey There is a new dev version of voxl-px4 located here: http://voxl-packages.modalai.com/dists/qrb5165/dev/binary-arm64/voxl-px4_1.14.0-2.0.61-202312011240_arm64.deb. Can you
wgetthat and then load it on top of SDK 1.1.1? You can then modify the/etc/modalai/voxl-px4.conffile to specifyRC=M0065_SBUSto use M0065 with SBUS. Once you restart you should have it working with M0065 SBUS. It has received very minimal testing at this point but you are welcome to give it a shot.
