questions about XMOS MCU and ultrasonic digital microphone
Posted: Thu Feb 08, 2018 2:00 pm
Hello everyone
I am an engineering student and I am working on a project of a microphone array. The digital microphones are Knowles SPH0641LU4H-1 that work in an ultrasonic range, to up 80 kHz.
I intend to use XMOS MCU to process the information this array: PDM to PCM converter; Filtering; delays; sums; beamforming; etc; but in the ultrasonic range.
Would I like to know if it would be possible to use the microphone array library in frequency ranges to up 80 kHz? Or this library is limited to up audio frequency?
If it does not work
Would it be easy to change this library or to develop a library to work in ultrasonic range?
Does it exist a library that it does it? Alternatively, are there resource in XMOS MCUs to use in my project?
Are XMOS MCUs good options for my project?
What is the best development kit to start?
I’m a beginner in XMOS MCUs and I would like your opinion about.
Thank you in advance.
