I want to start with my project on Portenta C33. I am politely asking for some hints or guidance.
Project:
"Connect a PDM MIC on C33 and send the PCM audio via UDP to a host"
I am familiar with Arduino, boards (e.g. Portenta H7). I am just asking if anybody have some hints about:
- assuming MicroPython on this board can setup a WiFi link, open an UDP socket, send any data...
- is there also support already for a PDM MIC connected?
(how and where to connect a PDM MIC? how to enable PDM MIC audio? Is there a conversion done from PDM to PCM already?) - or: how to use the I2S on C33? (for an external codec)
Just related to connecting a PDM MIC and how to use it. Everything else I should be able to figure out.
Has anybody used already a PDM MIC on C33?
Thank you.
The project goal:
"Visual Flight Radar": tracking aircrafts via sound and distinguish type and model (based on "audio finger prints").
