Change input/output signal by push button

Hello DaNhanCach,

Please try the attached project. You have to do some work though. Since I have the sigma350 core in my desk, I made the project for sigma3xx processors. However, I made this project by only using the blocks which are available on ADAU1401, I avoided using shifter like blocks which is not available and needs additional logics to implement shifting operations in sigma200 core.

So, you have to change to 28.0 format wherever I used 32.0.

I quickly prepared this project, just change the settings to get the correct hold time. I believe it will give you an idea, but I haven't tested this completely due to time constraints, maybe I will update it tomorrow if anything is needed.

This was working perfectly with sigma3xx core since it has a pulse counter with interval block. (sigma300 core users can use this)

Please copy this project for your ADAU1401.

Any other ideas from forum users/experts are always welcome.

Thank you for your interest in my question. I saw your project. it's still not what I want. I want when the output changes the input should not change.

I edited it but it looks too complicated. Hope someone has a simpler idea.

     Hello,

     My attempt to simplify this application saves a few instructions by eliminating the Divide block.  It runs on a ADAU1701MINIZ board, which has its middle button wired to MP3.  Since the button grounds MP3 when pressed, I inverted MP3 in the Register settings.  A short button press (between 0.5 -- 2 seconds) switches between two tones, a longer press moves the sound between left and right channels.  Any change occurs when the button is released:
