@Mazerunner, first get a good power supply 5V with at least 2A output to provide power via mini-usb, this is a main problem for many Pi communication. Have you checked if the module is installed and running? enabled I2S on the config.txt? All your setup following step by step the tutorial you've mentioned on adafruit should give you SCLK on pin 18, FS/WS on pin 19 and SD on pin 20, please check all the steps on terminal to see if ther is any error. Do you have an oscilloscope to check those pins?Mazerunner wrote: ↑Sun Mar 04, 2018 6:40 pm@ LisaJK
I happened to see your post and I'm working with the Knowles Mic on raspberry pi 3 .I've followed the adafruit I2S mems mic guide to set it up with my pi 3 ...I've loaded and compiled the kernel module driver with the following link guide including the wiring but my VU meter doesn't move from 00 when I run arecord and my Knowles Mic doesn't record anything,Also im using a USB port to power up my raspberry pi 3 do you think could be a factor of less power?.Can you please guide me on how you set up and if the link I'm following is accurate for the Knowles Mic .
