Re: GPIO on the Au1500

Hi Gilad,

A little while ago I wrote my own GPIO driver for the Au1000, mainly as 
a learning experience. I never bothered to release it because a driver 
already exists and I thought it was working. I'm not sure if it will 
work on the Au1550, but if you're interested you can find the source 
code here:

Cheers,
Charles
