Hi,

I've uploaded MWOSD firmware and one of its feature is that you can change most of the settings via gui interface using your transmitter and goggles.

Best regards

hi,

I have the rodeo 110, i have found this thread seraching for rodeo uart.

I whant to do the same for the rodeo 110, for the osd it's simple.

But i am looking to add a gps or other sensor.

Could you explain how to determine the pin for the serial port?

I don't have an oscilloscope.

please check this two picture

back & front

there are a lot of solder pad ex:

  • on the front nearthe usb (clk)
  • on top 5v
  • the camera connector is the jst near the usb
  • the vtx connector is on the back between the antena (black 6 pin)

FWIW, if you intend to fully integrate the OSD with the Flight Controller's data it will also need to use a serial port for MSP data.

Use your ohmmeter and determine if any unused connector pins or bare solder pads are connected to the Flight Controller's CPU. Also determine if any CPU pins are unused (nothing connected to them). If you find any of these things, consult the CPU's data sheet and Cleanflight source code to see if they are useful for UART or soft serial.

If your only requirement is to connect the GPS to the MinimOSD to display common GPS data then you don't need the Flight Controller's Serial Port. Use "standalone" connections instead, as explained here: http://intofpv.com/t-osd-standalone-gps

Thanks for your reply.

The best is to found the serial header for a complete integration. (but i am not sure to understand the benefit of the full integartion)

The fallback is to use the autonomous minimosd + gps like in the pimousse tutorial.

the initial target is to be able to found my drone in case off crash & the pimousse solution sem's to be a good solution.
