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...
Hi, I am using MP34DT05TR-A microphone with stm32f401re mcu. What is the I2s clock frequency required to get 24bit data at 48Khz sampling frequency. I also need to know the rate at which the data will be received from I2S?. Is it same as the sampling...
Hi all,I'm an NRF52/PIC/Atmel programmer which hasn't as of yet touched on STM32. I have a requirement to build a Audio 2.0 USB to I2S converter. Someone on Aliexpress has done it and it looks like the simplest way in terms of chip and components and...
Dear All,It is my first message here, so I would say hello to everyone.I'm trying to send some audio signal through I2S bus on the discovery board using the onboard CS43L22 audio codec. I've configured the codec using I2C and I2S on SPI3 peripheral.I...
My end goal is to have an USB-to-I2S device running on STM32F411, built using the HAL and customizable.I'm trying to port the USB Audio 1.0 Playback example from https://www.st.com/en/embedded-software/x-cube-usb-audio.html to an STM32F411 target. X-...
Hi guys, Ill keep this short, anytime I set the I2S bus to use FWS = 196KHz it acts all whack.I am not sure if its the tool I am measuring with but its a saleae logic analyzer so I doubt it. Here a picture of what I am talking aboutI double checked e...
Hello everyone!I am struggling with playback via I2S to external DAC on STM32L051/53. Audio:file in external SPI flash,WAV format16KHz sampling rate16bit depthI run the core on internal oscillator. My 'real' I2S clock (WS frequency) is 15,957kHz, whi...
We want to design a USB 2.0 audio device with I2S output with 192 or higher sampling rate. We didn't find a reference design with STM32F446MCY6TR and STULPI01BTBR. Could you confirm that this will work together?
Hi, I'm trying to L432KC to play WAV file using Adafruit MAX98357 I2S Class-D Mono Amp, SAI+DMA and I2S protocol.The code is running as one the tasks of FreeRTOS, but getting rid of RTOS doesn't help.WAV file is read from SD card, and I've already be...
