FrySky R9MM Support? #111

Closed Pablo18011 closed 1 year ago

Pablo18011 commented 1 year ago

This a great project, I have this working on a ACCST R-XSR through S.Port and works perfectly. However, I’m unable to get this to work with a R9MM receiver using the last flex firmware. I'm using RP2040 and v0.10. S.Port/F.Port or Inverted S.Port connections my TX is a 2018 ACCST Plus ( not the 2019+ version). Is the reason F.Port is not supported and the Inverted S.Port actually needs to be inverted to work? I have tried to post this question on openrcforums, but I'm unable to register as user...

Ok for anyone else using a R9MM msrc does work! F.port is not supported, so you flash "FW_Ranger9_RX_FLEX_20190201" firmware if using ACCST. Choose "R9_MINI_FLEX.frk" this is the standard version and not F.Port version. Use the "S.PORT/F.PORT Pin", with this firmware only S.PORT will out put from this pin. connect this to the RP2040 and GND. :) I have only tested this with the Voltage sensor. Why bother? well my R9M ACCST system has worked really well with no fail safe or range issue's, I had a spare R9MM and I wanted to use this in a glider, I only need 2-4 PWM channels, however I needed Vbat on my Taranis. The only other way to do this was to add a FC or a different RX. Thanks to MSRC project this is now possible for me with minimal weight and the option to add other sensors :)
