I am using STMCubeIDE latest and an F411CE.I used the MX wizard to enable USB_Audio class device set to 48000 s/sI configured an I2S with master clock on IS2.It plays whether I start the circular DMA in the AUDIO_Init function or in the AUDIO_CMD_STA...
I am using the demonstration program of the STM32G0C1E-EV board. I have changed the wave_recorder.c program in order to introduce the DAC with DMA in the same parte to be able to transmit the data from the microphone to the headphones directly instea...
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 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...
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 ?
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...
Inquiries regarding spiritDSP.We are implementing mp3 with DAC DMA using SpiritDSP.The time to play depends on the samplerate and bitrate of the mp3 file.The original time is 3 minutes and 10 seconds,The playback time is different as shown below.The ...
Hi there,I'm designing a PCB which will feed audio at 48KHz / 96KHz / 192KHz to a DAC over I2S (TI PCM5242).I'd quite like the option to have USB - in an ideal world, USB Audio, but at the very least a COM port (USB device).For the DAC, I'd need an H...
Hi,Greetings!Wondering whether the following logic works:Configure TIM7 for a sampling rate of 48khz. TIM7 triggers DMA to fetch audio samples at this rate, dumps it into the DAC buffer.Is this the right path ?If so, how to go about with the dual cha...
Hello,I am sampling audio data with sampling rate 16 kHz and then send it using RF to the other MCU which is sending to DAC samples with the same 16 kHz sampling rate, Im using DMA for sending data through I2S to external DAC. The problem is that the...
