WL500gx GPIO shit

[mistraller]

I would like to use GPIO lines for monitoring some signals, and to power an external led.

I have no clue however, how this should be done. I've read something about the diag driver on OpenWRT, but I run Oleg's firmware.

I have a wl500gx (deluxe)

I see something about gpio in /dev/gpio but I don't know how to use it.

I want to monitor three states on each gpio line: on/off/flashing (1 sec interval on-off)

Anyone?

You can use USB HID device (keyboard) as input/output interface. Input - keys circuit, output - LED line.

All 4 usb ports are in use, and GPIO is free to use. I don't want to add an USB hub, if gpio ports are available.
Maybe not the easiest solution, but the most interesting for me, because i want to know how GPIO works.

well, if you need only reading by router from these GPIOs, I guess it is the easiest. Just read continuously:

cat /dev/gpio/in 

then change the state of the pins and see the changes in the value obtained and try to figure out which bit is which.

To write to /dev/gpio/out you should provide first a bit mask in /dev/gpio/outen
