Posted on June 03, 2016 at 11:17Hello,In order to use both SAI_A and SAI_B, both in slave mode, on a STM32L4, I am wondering if the SAI_CK clock is used ? An external device is supposed to provide the BCLK and the FS clock (in my case), and the refe...
Posted on May 23, 2018 at 08:48Hello.,.,I used STM32F765BIT MCU SAI interface in slave mode to capture 4 channel audio inputs(TDM mode), I am using DMA (in Circular mode) to receive the audio data and it is working fine , But now I am upgrading to ...
Posted on February 21, 2018 at 13:26Hello.,I need to write test code for Audio codec which is interfaced through SAI interface . For this I am generating 1KHz sine wave using DAC and given to codec input and capturing the same through SAI interface ...
Posted on November 07, 2017 at 20:25So, I have 5 TDM data slots being used in my SAI1 master TX using circular DMA. I have a buffer that is 10240 bytes in size (5*1024*2). So, to start the TDM signal, I call: HAL_SAI_Transmit_DMA(&hsai_BlockA1, &D...
Posted on November 03, 2017 at 17:25I have been developing a TDM audio system for a multi-mono output system. I had the SAI1 BlockA working great a few weeks ago but now I'm not getting anything out of the MCLK or other pins. I haven't changed the...
Posted on July 26, 2017 at 09:58Hi Communities, can any body please explain me, how works exactly the function HAL_SAI_Transmit_DMA(). I am using STM32F746VGTX.This is one example:uint8_t TestArray[4] = {0x00,0xff,0x00,0x00};HAL_SAI_Transmit_DMA(hsa...
Posted on February 15, 2017 at 09:59 Hi, I'm having toruble with configuring SAI clock. For 48kHz sampling rate I need 12,288MHz MCLK but I'm confused with settings in CubeMX clock configuration tab. To SAI2 clock to arbitrary 24MHz but what shou...
Posted on February 15, 2017 at 01:52I can use one SAI RxTx channel or Two separate SAI ports, providing independent Rx and Tx channels.Which solution supplies the best HD stereo audio quality ?My processor board is based on the STM32F7The design ...
Posted on February 10, 2017 at 16:55Hi,I'm trying to communicate with http://www.analog.com/media/en/technical-documentation/data-sheets/ADAU1761.pdf via SAI, STM32L476 is master. I sucessfully connected to it via I2C, now I need to send data. I don...
Posted on November 20, 2016 at 17:52Dear all, I have a issue with SPDIF_TX on a nucleo F746ZG. Working on this since some days and can't identify the problem. I have some hearable ''glitches'' in an otherway working operation. A frequency sweep si...
