code for PDM microphones
Budget: €60 – €160 EUR
I need only the code integrating 2 microphones. Both microphones are from Knowles - SiSonic and use PDM communication.
Both microphones are communicating in real time with ESP32-Wroom.
Can be used Arduino or Espessif under VisualStudioCode.
Sounds must be saved on SDcard file.
Frequency of the samples around 46KHz.
Time for sound samples registration: at least 60 seconds.
Synchronization of the registered data is important.
Functional code will be provided from your side. I use VisualStudioCode for development.
In order to make my configuration, a Config file should contain esential parameters as number of microphones, select L/R, frequency, name of the file, etc. Comments inside of code are compulsory in order to understand your code.
Time for the project to be done: max 7 days.
Before to bid, take account that I will not increase my budget for this project.
If you don't have experience with PDM microphones....please, don't spend your time with me.
