S.BUS Conversion for Sentinel
-
Hello, I'm trying to retrofit an early Sentinel design with an S.BUS receiver. The Sentinel has been upgraded to the most recent SDK 1.1.3. In this model, J18 is taken by the VOXL ESC board. A Spektrum receiver cable is split between J10 and J19 and going to the older Sentinel Spektrum bind board. If I could utilize the J19 as an S.BUS input, that might be the way to go? I'm not sure how to ensure the PX4 stack is looking for the RC S.BUS signal on J19 rather than J18 like usual. Any thoughts appreciated, thanks!

@JoeC The Voxl2 does not support sbus. You would need an adapter board such as https://www.modalai.com/products/voxl2-io?variant=40610514206771

@Eric-Katzfey Thanks Eric, Apologies, I needed to also indicate that I've got a VOXL2 IO board in this as well. Hence, I should ask, "Can J19 be used as a UART that goes to a VOXL2 IO board?"

@JoeC What does your
/etc/modalai/voxl-px4.conffile look like? For your desired configuration you should setRC=M0065_SBUSandESC=VOXL_ESC. -

I've confirmed that I was able to use J19 with the "RC=M0065_SBUS" option successfully. Hence, if no VOXL_ESC, one should use J18 for the VOXL2 IO board and if there IS a VOXL_ESC board, one should use the J19 for the VOXL2 IO board. The firmware seems to be "smart" enough to figure out as long as /etc/modalai/voxl-px4.conf is set as you suggested.
