First time here? Check out the Tour!
I am connecting the AKU242 straight to our microprocessor. It is a PDM interface so it has a SELECT, DATA, CLOCK, VDD and 5 GND signals. On the datasheet, there are two identical PDM microphones with one SELECT connected ... (more)
What is the most energy efficient microphone input method, PCM via I2S or PDM. Does the SoC have a special HW handling of the PDM format for converting to PCM? Does the filtering of the 1 bit conversion compete with ... (more)
I'm starting a new design on nRF52 and I need to connect a microphone on it. Reading the datasheets and questions here, I found there's 3 solutions for the type of microphone and interface to nRF52 :
As I know, nRF52 support PDM mic. So, I'll make recording sound with nRF52. But, I do not find PDM example on SDK 11.
Please notice me, where is the PDM mic example.
I would like to know how can I use nrf52832 preview kit for audio application, i.e. I would like to use PDM interface of nrf52832, please guide me on how can i do that.
yesterday i ordered th nrf52 Development Kit an just had a look in the Errata http://infocenter.nordicsemi.com/inde... So if i get my Development Board, will all this stuff marked up in Errata not working to me ... (more)
