I want to interface two electret microphones (stereo sound) to STM32F446 chip. I don't know how to connect it or what protocol or pins I have to use. I have found a lot of information about digital microphones but nothing on this topic.Thanks.
Hello. I work on stm32CubeIDE. I am trying to figure out X-CUBE-USB-PD. An example of the project I'm trying to parse can be downloaded from the link https://github.com/STMicroelectronics/x-cube-usb-pd . It is required to understand how to adapt this...
I am having trouble getting independent stereo audio output on the STM32F469I-DISCO development board. I am passing data to the cirrus audio codec using the stm32469i_discovery_audio.h functions:BSP_AUDIO_OUT_Init(OUTPUT_DEVICE_BOTH, 80, 48);BSP_AUDI...
Dear all,I have some trouble setting up the correct acquisition of the MEMS microphone over I2S.Consider the STM32F401RE Nucleo board connected to the IMP34DT05 PDM microphone with L/R to GND.Through Mx, the I2S peripheral is configured as follows:Th...
Hi! I am trying to generate a sine wave on my CS43L22 audio codec chip and use the included stereo jack on my STM32F469I-DISCO board. I'm using the STM32Cube IDE. There is one .WAV player example that I can't get to build in the IDE that's closely re...
Hi,i am using stm32f411e - Discovery Boardi want to know how to play any audio files through cs43l22i am using flash ic Doubt is that how to convert audio file into binary file save into flash memory & send the same to codec ic.only 2 audio files Kin...
Hi all,after developing the firmware for a composite USB application (AUDIO + CDC_VCOM) for an STM32F446 device, I'm facing strange behaviour in the driver side for Windows (I've tested both 10 and 8 with the same results) - Linux and MacOs works out...
Hi,I want to implement a speech IO using stm32f401 discovery board.In this case I am using the onboard digital microphone to acquire the PDM samples using spi2(I2S) interface. After that I am using the PDM filter to convert the PDM samples to PCM sam...
I don't think that what I am asking is possible with the STM32476 that we are using, but it would be nice to have confirmation. We currently have a stereo setup that uses two I2S microphones hooked up to SAI1. Everything works great, but sometimes we...
