Please help I am having problems with my setup.
Watch the Video here: https://www.youtube.com/watch?v=NuBPU8GDXsc
Mini build from Space One FPV (Formula 220 frame)
I am going cheap and light.
Flight Controller: Naze32 (rev5)
Receiver: FrSky X4R-SB
Controller: Turnigy 9X v2 (w/SmartieParts SP Basic Programer
Controller Firmware: ER9X Latest Binary (not FRSKY)
Module: FrSky XJT Module (no telemetry modifications - plug and play, no modifications done to turnigy 9x)
I wanted to use the Naze32 board because its cheap, small and light. I got the FrSky X4R-SB because it is cheap ($24), light, small, and has SBUS, which will give me up to 16 channels with just 1 servo cable!
Problem is Naze32 rev 5 does not understand the SBUS inverted signal from the X4R-SB receiver.
I didn't want to have an inverter cable, or modify the X4R-SB receiver. But I read you can update the firmware to the receiver, and it will output a non inverted signal that the Naze32 can read. So I did that!
The Turnigy 9X has ER9X installed on it and a FrSky XJT module. I was able to get a bind with the receiver no problem.
I followed the steps in this video: https://www.youtube.com/watch?v=kGXGn9b7WiU
Wired the X4R from SBUS port to pin 4 on Naze32, in cleanflight I changed the port UART2: Serial RX, and in configuration I changed receiver mode to RX_Serial as well as Serial Receiver Provider to SBUS.
When I do a receiver test I get nothing out of the sticks.
Solutions I would like to stay away from:
Purchase Naze32 Rev6
Purchase Inverter Cable
Modify the X4R-SB
Things I assume could be wrong:
Updated X4R-SB Firmware is not working???
Turnigy 9X and XJT module needs hardware/firmware changes???
Have you figured it out?
Right, I did built a small inverter and tested the sbus inversion feature on rev5, it doesn't work.
I mean, without the inverter, on or off show no readings. with the inverter, both show readings.
