Thank you very much for the very helpful explanation and example Micropython code. A relevant discovery I wanted to share; while cutting the signal does not stop the receiver from transmitting signals for each channel, one can engage a failsafe mode for each channel from the transmitter, with a custom level. That way, if the signal between the transmitter and the receiver is lost, the signal for that channel will revert to the failsafe level set, and not to the last signal received. To adjust the failsafe for the FS-IA6B receiver using the FS-16X transmitter, one navigates to System->RX Setup->Failsafe. Select the channel and adjust the failsafe value by manipulating the relevant channel on the control. Then, when the list of channels is displayed again, long hold the Cancel button to save the setting. For the dials (channel 5 and channel 6), the setting should be -100% on the transmitter to failsafe to 0 as the signal for the Pi Pico if one is using the very helpful example ibus code provided by Penguin Tutor (Stewart Watkiss).

I really enjoy the work you put into your projects. I would love to see you expand this example to work with all 10 channels of the FlySky FS-iA10B. Maybe even in such a way the all of your FlySky FS-iA6B viewers could reconfigure their controllers to include one or more of the toggle switches and then make use of the FlySky FS-iA10B example. Keep up the great work and informative videos.

just what I needed! Excellent explanation my man

Nice work! I recently got sbus to work on my Raspberry Pi 3. The main challenge with SBUS is that it is a 100000 baud rate protocol, which is not something the standard UART supports on the Raspberry Pi. But I was able to get it to work using a plain GPIO pin and getting the timing of the edge transitions from pigpio. Because the Rasperry Pi 3 is not a microcontroller, sometimes I lose a packet I think due to context switching. But around 75-80% of the packets are good (checked with parity and UART frame bits). I haven't stress tested it yet, that performance might degrade under load. However, the transmitter is transmitting a packet every 10ms or so, so a dropped packet just increases the lag to 20ms, which is plenty acceptable. SBUS has 18 channels, which is nice, though probably overkill in most situations, and most transmitters transmit RSSI (radio strength) on channel 16. Anyway, I am thinking of posting a video and releasing the code. I haven't done that before so that might take a bit and I really need to clean up the code and make it ready for others. If/when I do so I'll edit this comment and add a link.

You save my day! Thanks and God bless you.

Thanks! Works like a champ. I was really hoping to find a Python port of iBus for my Flysky.

Amazing work !

What's follow up video with servos working control the servo with flysky nice to see in working not just date

Thank you

That's great!

Interesting Video! Do you also know how to do this with a ELRS-receiver (like Radiomaster RP1), which uses the Crossfire protocol (crsf) over uart? So far, I have not yet found the library for the crsf protocol in micropython.

I get "ImportError: no module named". Any idea what cases this?

Great video! Thank you. Can we run it on Raspberry Pi 3B+?
