특징
-
There's a few ways to manage these mics:
- Your chip comes with a hardware peripheral and library that does all the data managing at high speed, collects samples, applies a filter and gives you an analog value (Ideal!)
- Your chip comes with a hardware peripheral that gives you values, then it is up to you to perform the decimation/filtering. (We have some example code for this on the ATSAMD21 chipset)
- Your chip does not come with a hardware peripheral but you're pretty clever and come up with a way to make it work (See this example for the ATtiny85)
- You generate the high speed clock, then add an analog filter on the data line, and read the analog value (A hack, but works!)
Either way you decide to go, make sure you have a handle on what support you get with your platform, as these chips are a little tricky!
Each order comes with one fully assembled and tested microphone, and a little header to solder on for breadboard-compatibility. Check out our full guide for wiring details, schematics, example code, datasheet and more!
