Control VTX through MinimOSD
#1
Hello everyone.

With most recent versions of ScarabOSD you can not only enter the standard MWOSD menu, but also the Betaflight OSD menu in which you can control more features of your FC and more - one of the features of Betaflight OSD is controlling the VTX settings for IRC tramp and TBS Unify.

Here's the equipment I used:
Micro MinimOSD
IRC Tramp
X-Racer F303 v3.0 (beware the reversed TX2-RX2 labelling...)

Configure the Micro MinimOSD
You need the MWOSD 1.6.5.0 (or newer) where CANVAS support was introduced. In simple words - it can communicate with the FC in the same way the BetaflightOSD equipped boards do and show additional information in the goggles.

You can now flash and configure MWOSD in two ways:
  1. old-fashioned way of hooking up an Arduino board. Before you flash, open config.h and uncomment CANVAS-SUPPORT, in newer versions, uncommenting BETAFLIGHT should enable it automatically.
  2. by using the new Chrome-based MWOSD configurator app and simply selecting Betaflight hex (what I used, so I can't comment on "manual" method)
Prepare the FC:
Solder the MinimOSD to the UART port (UART1 in my case)
Solder the T wire from Tramp to a free TX on your FC (TX2 in my case)

Open Betaflight Configurator and Ports tab and open "Peripherials" dropdown to select "IRC Tramp"



Done, you can enjoy easy channel change without relying on that God damned button  Cool



Have fun!

Do you know if it is possible to show the pids while flying as well?

I don't see that option in osd menu overlay. Where is it configured in case of betaflight OSD? If it is in betaflight configurator, then this tab is inaccessible with minimosd.

It can be turned on/off in the bf osd (not betaflight gui)

I am using the SP EVO F3 with my Flysky X6B Receiver and the Tramp HV V2 VTX. The Receiver is connected to UART2 and my minimOSD is connected to UART2.

I am guessing that I can't use the Telemetry Port on UART2 even though it's not SBUS. IBUS will probably also block it. How do I have to connect the  VTX Telemetry? A lot of times i read that the USB Connector is a dedicated one so UART1 would be open for use, but sometimes i read different statements, all about the same FC

You can use uart1. In my example I use it for OSD. It gets blocked only if micro minim is powered up from pdb. I can still use USB connection as long as it is turned off

Come to think about it, it shouldn't block the Connection at all since it's only using the TX of UART1 and not the RX

The flight controller in the picture is a Seriously Pro F3 flight controller, not an Evo!
