Yes BD, I did. I am using a standard Futaba 9 CAP TX with the standard AETR,A1,A2,A3,A4 FM RX.
The SP F3 has these two very oddly laid out IOs sharing the 8 channel between them. (see photo attached).
I have assumed that either IO can be used to connect the RX and have tried both and several other combinations all to no avail. I also assumed that the order goes SP IO-1 channel 1,2,5,6 connects to RX channel 1,2,3,4 in that order. I could find no relationship between the two channels that did work the RX display in Cleanflight RX page. Throttle stick Ch 3 worked AUX 2 and Rudder (Ch 4) stick worked AUX1 and no other channel moved with any TX stick, slider or knob.
IO-2 moves when hooked up 3,4,7,8, moved CF receiver bars 7 and 8.
Here are the IO descriptions from the manual;
Interface definition
IO_1 connector - PWM RX / PPM RX / GPIO / LED Strip
When using a PWM receiver connect CH1/2/5/6 to PWM RX.
LED Strip data signal can be used to change individual colors of each LEDs on a strip of WS2812 RGB leds - Perfect for battery warning lights, orientation lights, indicators, failsafe, display flight modes, etc.
CH1/2/5/6 can be used as a general purpose IOs when not used for PPM/PWM RX.
A 3.3v output is also available.
IO_2 connector - Serial RX / PWM RX / GPIO / UART3
When using a PWM receiver connect CH3/4/7/8 to PWM RX.
When using a 3.3v Serial RX receiver (S.Bus, SUMD/H, etc.) use GND/VCC/CH3 (UART3 RX).
CH3/4/7/8 can be used as general purpose IO when not used for Serial/PWM RX.
CH7/8 can be used for a 3.3v Sonar sensor when not used for PWM RX.
ADC_1/2 can be used to connect Battery Current Monitoring and RSSI signals. (3.3v MAX).
OUTPUT
It is all very confusing and I just do not know where to go from here. :huh:
Everything else is working perfectly.
