Want LED indicators on GCS of specific errors and Operations

[Aliraza_Mehmood]

Hey there,
I am working on GCS in which I want to add LED indicators of specific operations like gps lock, manual/auto and RTL on GCS so that I can see these things from LED indicators rather than go and check in HUD window. If anyone does this before kindly assist me the way I can do it.

Thanks

my best guess is you would need to program an arduino to look for specific mavlink messages on the telemetry link and then turn on pins connected to leds.

MAVLink and Arduino: step by step

MAVLink and Arduino by Juan Pedro López This is not a post on the details of MAVLink serial protocol. If you are interested on the protocol itself, you can read the fantastic post by Pedro Alburquerque: This post will be focused on my experience and practical use of MAVLink protocol on an on-board Arduino (Nano with ATmega328) that communicates with a Pixhawk flight controller (a clone one, v2.4.8). I am using the Arduino to control the lights of my drone (WS2812B leds) and the code you will…

Thanks for the quickest reply. But I want to see these indications on GCS not from my flight controller. I want to get specific messages from mission planner and turn these messages into led indications for better user experience.

you dont have to get the mavlink stream on the vehicle, you can either tap the TX wire from the telemetry radio as it goes into the laptop or you can CTRL+F in mission planner and select mavlink mirror to output to another serial port with the arduino attached.

Thanks for the help highly appreciated. I will look into it and post the progress thanks
