Nordic nRF52 PDM Microphone Project I am seeking a software developer who can assist me in developing a Nordic nRF52 PDM microphone. The microphone should measure sound level in dB. Ideal Skills and Experience: - Proficiency in software development for Nordic nRF52 in KEIL with SDK by Nordic It is necessary to implement the code for the microcontroller in C . It is necessary to receive data from the MEMS microphone MMICT390200012 via the PDM interface. Microcontroller Nordic nRF52832. ARM KEIL development environment. The environment is already configured and there is a project. The official SDK from Nordic nRF5_SDK_17.1.0_ddde560 is used. All peripherals, UART for debugging are also configured. PCBA is factory produciton. Scheme in the attachment Algorithm: Set up the PDM interface. It is necessary to supply power to the microphone through PCA8574APW, 118 (the code for PCA8574APW is already configured, there is a function, it works). Function is PCA_setstate(PCA_MIC) to turn on and and PCA_setstate(PCA_OFF) to turn off power supply for microphone. Start collecting data from the microphone, fill the buffer. Make a conversion and get a measurement of the sound volume in decibels. There is a function prototype to implement: PDM_init(); // init PDM interface db_value=Get_Dec(); // to get data from MIC. you need use siparatly pdm.C and pdm.H files for you code. The task must be done quickly in 3 days. I give access to the hardware platform and PC through Anydesk.
