Channel question

[KONGFPV]

Hi mate do I need to set the number of sbus channels anywhere? I can’t get it to work! Using arduino nano Tx pin wired to right port on hoverboard ibus connected to tx pin on nano Sbus from crossfire connected to d3 pin Ibus variant flashed with 14 channels config as default

I have never tested it with crossfire, I usually use it with a flight controller SBUS output.

It wont work if you connect it to a Y lead with more than one device. it needs a dedicated SBUS output.

how are you powering it? do you have 5v connected to raw or vcc?

Hey mate, powering via 5v pin, Would this be the best way to get a 4wd platform running? Did you end up using your converter I. The end? I was following your build on the ardu forum it’s amazing

[geofrancis]

yes i use it for both my 4wd rover and 6wd rover using the SBUS output from a flight controller. are you sure you have your receiver set to SBUS and not CRSF?

[KONGFPV]

Yeah crsf rx definitely set to output sbus ch1 Are you available on messenger at all? Add me! Brady heathcote from Australia

[geofrancis]

do you have different receiver you can test?

[KONGFPV]

I do, by any chance do you know if the subs signal needs to be inverted or uninverted? Do you know if the hoverboard will detect the ibus signal without a working sbus input? I’m getting 4 beeps still

[geofrancis]

The adapter doesnt output anything unless it gets an SBUS frame, it uses standard SBUS, I ran it direct from a FRSKY X8R receiver SBUS port.

what channels do you have your outputs set to? the adapter is configured to use channel 1 and 2 for the motors.

[KONGFPV]

I’m not getting any movement what so ever, my rx is set to output sbus on ch1, I notice the lights on the arduino nano are blinking before I connect my rx then they go solid, is this normal? Do I have to set the ibus output pin in your code?

[geofrancis]

if you connect USB serial to the arduino serial pins what do you get out?

[KONGFPV]

Do you have Facebook bro? It will be much easier to message on there, I’ll google how to connect usb serial now and have a look

[geofrancis]

you didnt upload it

what arduino board are you using?

[KONGFPV]

[geofrancis]

That looks like its working, I think its either firmware or wiring to your boards thats the issue.

[KONGFPV]

Did you connect the right short cable or the left long cable to ibus? Also if I added 100nf capacitors to the signal lines should I remove them?

[geofrancis]

it wont work with the capacitors, those are only for PWM input. I think it uses the right side by default.

[KONGFPV]

Woohoo! Success! She works as soon as I removed the capacitors!!

[KONGFPV]

My next question would be can I just y the ibus lead to multiple controllers?

[geofrancis]

Yes you can split the ibus output between all the controllers.

Awesome thanks so much for your help!
