Hi. The HAL_I2S_Receive_DMA() has defect around its size parameter. The UM1905 explain the size parameter as following :when a 24-bit data frame or a 32-bit dataframe is selected the Size parameter means the number of16-bit data lengthThat mean, rega...
Hello,I'm planing to receive audio data from an Audio codec (ak4619). I need to receive signals from 4 microphones and this device permit that through two left/right chanels.In CubeIDE, I selected a MCU (STM32F446RET) and declared two I2S connections...
I am using STM32F446 Nuclero and STM32CubeIDE.I wrote a loopback code from I2S_ADC (PCM1808PWR) to internal DAC.MCU is slave mode (external clock to IS2_CKIN).I works fine. However, when I try to "Pause DMA" and "Resume DMA", I2S of MCU does not sy...
I'm using the ST32F4 discovery board, and would glad if someone could explain the relationship between the PLLI2S Clock setup in CubeIDE and the actual I2S2_CK (PB10) to the mems mic. I my case I use PLLN=192 and PLLR=3 giving 64MHz I2S Clocks. ...
Hi,I wrote a simplest program (below) to send sine wave data to PCM5102A (DAC) via I2S.However, I found only L-ch data is valid and R-ch has no data.Analogue (DAC) output of L-ch is somewhat sine wave, but it is sometimes de-formed. And if I look i...
Hello,I managed to get full duplex I2S + DMA working on an STM32F405 with Cube + HAL, however have now switched to an STM32H750 for more processing power.In STM32CubeIDE version 1.3.1, while there is an option to add a DMA stream for TX, there is unf...
Hi,I am using STM32CubeIDE for audio application development. In my application STM32 will be working as I2S Master Receiver so I wanted to collect data continuously without losing any data.I have configured DMA with circular mode enabled. Looking at...
