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...
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,I have already ported the USB AUDIO DAC application code to STM32F401VC Discovery board. After running the application I am getting noisy audio output from the codec.Please check it & inform me if you found any mistake(it could be in configuration...
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...
I am using F446 board with CCA02m2.when I just send the audio to USB output, I can record data in audacity. But if I do simple processing such as averaging data, the output is high clipped data.I checked the data range and overflowing. there is no pr...
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...
Hello everybodyI want to use speex in my project based on st application note in speex demonstration and it's code ... my hardware is f407 discoveryMy question is : is there any option to implement speex in wideband mode with good quality in f407 boa...
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-...
Im using stm32f429 controller,now in our project i want to play audio in wav format.now sd card read function working fine,data transfer from uc to DAC using i2c DMA mode.but now only noice is play.what to do now ?any suggestion ?
I want to test out the usb audio device middlweare but it seem the i can't recive any audio packet, the device is configured and stall after. no isochronous transfer is done. The code is just out from cubeMX with no modification. Is there more i have...
