PUSHBUTTON AND LED ON AND OFF WITH TIMER ON ADAU1701

Hello Frish,

You mean press a button and the light goes ON after a delay? Then it stays on for a period of time?

Is the switch momentary?

Do you have the ADAU1701 eval board?

Hi, i mean exactly what you wrote.

I've a evaladau1701 with miniz board.

Thanks

Hi, Dave & Frish,

You can accomplish this function with a One-Shot Rise Reset and two Timers with External Reset.

The One-Shot latches GPIO_2 when you press the button. The first Timer sets the delay before the LED goes On. The LED stays On until the second Timer times out, which resets the whole thing via the Feedback block. Timing is by samples, with 1/48000 second resolution. The attached project runs on the ADAU1701MINIZ board.

Best regards,

Bob
