I have project at adau1701, The funcional requirements is when analog signal input ,External leds via GPIO to control.
LEDS exhibit of lanterns with the size of the input analog signal to flash,how to establish the project file? thanks!
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.
Thanks for your reply. but i open the exmple with adau1701_led_levelmeter , the demo board havenot LED
to flash via MP10 . I donot know why.
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.
