i hope you can help me out here because this is super critical to me (writing my bachelor thesis right now).
My setup consists of the Arduino MKR Zero and the Infineon's MEMS Microphone "IM69D130".
Links for the Microphone: https://www.infineon.com/dgdl/Infineon-IM69D130-DS-v01_00-EN.pdf?fileId=5546d462602a9dc801607a0e46511a2e ; GitHub - Infineon/IM69D130-Microphone-Shield2Go: Examples for Infineon's MEMS microphone based evaluation board IM69D130 Microphone Shield2Go for Arduino.
The MKR Zero is specialised on audio data and has I2S Bus. The IM69D130 also communicates via I2S.
How is the correct pin matching?
-> My solution so far:
-> MKR Zero IM69D130
-> SCK (pin 9) <-> I2S:CLK (or I2S:WCLK in my case because that is printed on it)
-> MISO (pin 10) <-> I2S:DATA
-> SS (e.g. pin 7) <-> I2S:BCLK
-> Is this correct so far? And also: Is it correct that the SS (slave select) can take any not used/special pin (e.g. pin 7, 6, 5, 4, 3, 2, 1 and 0)?
How do I have to code the software in order to manage to successfully read audio data from the sensor and store that data via a .wav file (or other audio file formats) in the micro-sd card? Is there any already uploaded/shared sketch which exactly does that for me or any code you smart people can quickly suggest?
For my application (which is a moving object with 2 m/s for about 20metres) i have to install this measurement setup on the system. Therefore i can not have my Arduino + sensor on a cable to my PC.
Is it possible to upload my code via PC with normal micro-usb connection, then unplug the Arduino+sensor from that cable, plug the power bank micro-usb cable to my Arduino+sensor and have still a running audio capture? In case that this does not work -> Have you guys any other working solution?
I would appreciate your help and intelligence guys.
