Inav: Full duplex softserial-1 for Matek F411-WSE

[Target0815]

Current Behavior

Softserial-1 is currently only a TX.

Desired Behavior

Softserial-1 should be fullduplex RX/TX

Suggested Solution

Fullduplex Softwareserial-1 as this is also generated by default as a target for Matek F411-Wing. Only a small change is necessary:

So far:

define USE_SOFTSERIAL1

define SOFTSERIAL_1_TX_PIN PB9 // ST1 pad

define SOFTSERIAL_1_RX_PIN PB9

New:

define USE_SOFTSERIAL1

define SOFTSERIAL_1_TX_PIN PB9 // ST1 pad

define SOFTSERIAL_1_RX_PIN PB10 // LED pad

This would give us 2 full UARTS (GPS, CRSF) and 1 Softserial e.g. for the DJI FPV System (OSD).

Who does this impact? Who is this for?

All users with DJI FPV system on copters and plane. Or of course all users who need a 3rd serial port.

Full ack!
For use of gps/crossfire/dji air unit it's neccessary to have a softserial with fullduplex RX/TX!

Does anyone have a build with this enabled? I found one at https://fpv-community.de/threads/matek-f411-wse-softserial.85747/ but I'm unable to download.

My F411WSE is also waiting to be used with GPS + Smartport + Caddx Vista. Would highly appreciate this feature!

@Feldsalat
Tested, works fine.
I do not have enough knowledge to make a pull request by my own. But if anyone does, I will be happy to test it, brew the coffee or spend a beer.

Is this a new firmware that I can flash in INAV? I need to use my Caddx vista
