adau1701 on LED

Hi lai,

I am not sure if this will help, but I have attached an example ADAU1701 project which uses GPIO6 to GPIO11 pins as a volume meter, based on the envelope peak block on the inputs. Also attached is a much simpler project which blinks an LED based on a square wave. Both examples should show the usage of teh GPIO cells and register settings.

Hi Lai

At some point we develop a library that would talk to SPI LED drivers. Let us know if this is what you are looking for. It used to work with an Alegro part.
