Do you mean Microphone(Audio data transmission) application using FM4? Do you have question or idea want to share here?
That's right .
Now micropython is running on STM32 FM4 and other MCUs,but no Cypress's MCU. I have an idea , if there is possible ,I want to try the GUI design and other fast designs using micropython. But maybe there are lots of difficult. So I need someone who has the same idea to help me.
