[Feature Request] Display VTX temperature in degrees C in OSD #234
Description
The goggle OSD shows a multi coloured VTX temp icon.
The VTX menu shows the VTX temp.
As of 1.7 the VTX temp can be queried from a Flipper Zero.
Can we please have the ability to position and display the VTX temperature using the betaflight OSD?
I gather this would involve implementing the Betaflight MSP_DP_SYS command as described here:
