Hello.

I have an old Asus wl500g just sitting around.
Out of fun I made a webcam "mount" (glued 2 servos together and than to the webcam), that can act as a pan/tilt for the webacm.
I can operate the pan/tilt usin arduino and its servo library just fine.
But, as arduino would mean additional USB port the old WL 500g does not have, I am looking for some option to drive the 2 servos directly using GPIO.
Did anyone ever tried this? I googled, but did not found anything for now
Thanks in advance for any hints...

There is a gpio-pwm module available, so what is mentioned in this video should be more or less possible: https://www.youtube.com/watch?v=ddlDgUymbxc
I just don't know, how exactly the timing of the router will be. Have a look at PCA9685, that chip is connected over I2C and allows setting pwm duty cycles (it is actually a LED dimmer) - and has lately got a kernel driver (although not yet included in openwrt, AFAIK).

Thanks for the recommendation.
To be honest, I would not like to invest much more into it.
I can probably use some of the ATtiny85 I already have and try the suggested i2c communication - it makes a lot of sense from my perspective to let the exact timing on something else than the router itself.
I'll get into it now.
Thanks again.
