Li-firmware tse tharo tsa mohlalaamples tse u lumellang hore u leke boto ea nts'etsopele li ka fumanoa ho X-CUBEMEMSMIC1 sephutheloana:
- AMicArray_Microphones_Streaming: ho fumana maekrofono le ho phallela ka USB
- AMicArray_Acoustic_SL: ts'ebeliso ea nako ea nnete ea mohloli oa molumo o sebelisang mats'oao a mane a fumanoeng ka li-microphone tsa MEMS tsa dijithale le AcousticSL middleware ho hakanya tsela ea ho fihla ha mohloli oa molumo.
- AMicArray_UltrasoundFFT: ts'ebeliso ea tlhahlobo ea boemo ba ultrasound e lekanyang FFT ea lets'oao la maekerofounu ea analog ebe e tsamaisa sephetho ho PC GUI ka USB.
