SmartEdge Front Panel User LED

shin8686
shin8686 over 3 years ago

Hello,

 

I wanted to figure out a way to control the front panel LED through a C# app (just trying to blink it on & off for now). I've played around with a standard Raspberry Pi before (controlling LED's through the GPIO pins), so I've made an app similar to the code from this link: https://docs.microsoft.com/en-us/dotnet/iot/tutorials/blink-led, but I'm having trouble finding out how I can access the LED. Is there anything specific I need to do to I access the front panel LED?

 

Thanks in advance.

    Is it the SmartEdge IIoT gateway? If yes, what image have you installed?

    All leds can be controlled. At this moment, one is assigned fixed to processor I/O activity, in the overlay. Thre is no programmable interface for it.

    The others have linux character devices assigned to them. By default, they are used by the Smartedge example application and by the watchdog hardware.

    I've tried to untangle and document this for the (as I write this) latest image: AVNET SmartEdge IIOT Gateway: the 2020 Linux Image - Understand the Custom Scripts and Services (Pt. 2: led service)
