Hello,I have a PDM MEMS microphone that I am reading in I2S master receive mode. I am trying to take this data and put it in a FIFO buffer and then output the data over UART using DMA. I must be confusing the buffer sizes because I get mostly zeros...
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...
I thought I had checked everything about the F767ZI Nucleo-144 and its pin availabilities. Unfortunately I overlooked that I2S_A is the only one whose peripheral pins are connected to the SPI_RX and SPI_TX regs for DMA streams.This means that for my ...
Hi All,Attachment is SAI in DMA mode source code generate from CubeMX, but the code doesn't works. DMA interrupt in this code can't be trigger so no data receive from SAI.I can run demo code SAI_AudioPlay on STM32L476 Nucleo board, it works.I can re...
Posted on November 08, 2017 at 11:21Hey guys,I have some problem with the output of my DAC and I hope you have some idea, what went wrong... Situation: I am trying to play a WAV audio file with the DAC of my STM32F407VET. I use a double buffer, t...
Posted on July 11, 2017 at 17:23Hi Communities,I am using STM32F745VGTX Chip for my audio playing wave file application. My problem is that playing wave file takes too much processor power, therefore I want to use DMA instead. Is there any DMA mode,...
Posted on April 24, 2016 at 15:07 Hello! I'm trying to output a sine wave on my CS4344 DAC using I2S and DMA but it's not going well... First step was to output the correct clocks ie LRCLK = 1kHz and MCLK = 256 * LRCLK = 289MHz. ...
Posted on April 09, 2015 at 12:02Hi! I am using STM405RGT6 and TI PCM3060 audio codec. I use DMA to RX and TX I2S data. I2S configured to 96000 Hz. When I set buffer size, for example, 64 samples I get parasitic frequency peaks at every 1,5 kHz (960...
