Inav: No Resource Remapping?

Created on 15 Mar 2018 · 10Comments · Source: iNavFlight/inav

I see where SOFTSERIAL can be enabled as a feature but I'm unable to free-up an unused motor pin to use with IRC Tramp. Is resource remapping undocumented or just unavailable?

iNAV 1.9 and Omnibus F4 v3

Resource remapping is extremely useful feature. Please implement it

i have the same thing :( its not yet implented in inav, maybe it will come later im also an omnibus user, betaflight has this function but inav doesnt have it yet, im using uart 1 for gps uart 3 for compass and uart 6 for sbus i need 1 more for frsky telemetery

OK. Thanks, shellixyz.

FinalX1992: If you have an Omnibus F4 V3 you might want to try the nav_1.9.0_OMNIBUSF4V3_I2C_REMAP.hex firmware found near the end of this thread: https://github.com/iNavFlight/inav/issues/2658

It appears to give you a fully functional SOFTSERIAL port (I haven't experimented with it much but it did appear to disable the LED strip feature.)

For the now the best option may be to switch to the Matek F722-STD board. It has 5 UARTS available and it is supported in iNAV 1.9

I have a F4V5 original omnibus board I'm installing into a fixed wing plane. Using iNAV, Wraith32 65A ESC, Frsky X8R, DJI NAZA GPS.
Not paying attention, I was going to use UART 6 for the GPS, RX 1 for ESC telemetry & TX 3 for Smart Port. SBUS needs UART 6 so I can move GPS to UART 3. Can I use UART 1 TX 1 for Smart Port & RX 1 for ESC telemetry?

If I can use UART 1 for both Smart Port RX & ESC telemetry on TX, how do I remap in CLI if remapping is needed? Set UART 1 to soft serial & bidirectional?

GS-AutoTech on 2 Apr 2018

The telemetry RX and TX would not need high priority as they are both used just to monitor system status.
I need all 6 PWM channels for servo output on the fixed wing. 1 & 2 allocated for ESC, 3,4,5,6 for elevator, ailerons, rudder & flaps
