This application parses a binary FrSky telemetry stream and displays the data onto the screen (currently voltage, height, orientation, lat, long). The application is intended to run on a Raspberry PI since it uses Broadcom specific functions for drawing onto the screen. The rendering however can easily be disabled by commenting the "#define RENDER 1" line in the conf.h file. In that case the values will only be printed to the console. Usage: ./frsky_omx_osd <font path> The font path should be a directory containing a .ttf file that will be used as a font. The binary FrSky data will be read on stdin. You could do something like this: cat /dev/ttyUSB0 | ./frsky_omx_osd . or (in case you are using wifibroadcast): /home/pi/wifibroadcast/rx -p 1 -b 4 wlan0 | ./frsky_omx_osd . To test the application offline a FrSky telemetry log is provided in this repository: ./frsky_omx_osd . < testlog.frsky
