There aren't any generic GPIOs numbers, so OpenWrt has to use device specific mappings. It means we need to find out GPIOs for every controllable LED and button on every supported device. GPIO LEDs If LED is controlled by GPIO, direction has to be set to out and we need to know the polarity: If LED turns on for value 1, it's active high

16.12.2008 · Location: Ohio. Posted: Tue Dec 16, 2008 1:21 Post subject: In other broadcom based routers I've used, the WLAN LED is directly controlled by the hardware. The LED is on if the radio is on, off if it's off, blinks with activity, etc. On my routers, the WLAN LED cannot be controlled with the gpio utility.

You'll need at least 1 free GPIO in your router. Also you need to locate VCC (3.3V) and GND, but this is a piece of cake. Prepare your hardware These are two schematics for connecting the IR LED to our GPIO output. Both should work fine. Simple circuit. It should work on any device
