Posted on October 20, 2016 at 13:17 Hi all, HAL_SAI_Transmit_DMA fromstm32l4xx_hal_sai.c v1.5.1 does not follow the sequence described in RM0351 Rev 4 pg 1329: ''In slave mode, the audio frame starts when the audio block is ena...
Posted on September 12, 2016 at 04:31The problem is that I have an *external* 24.576 MHz MCLK. In master mode, how do I get that from outside the chip onto the SAI_CK_A or SAI_CK_B clock?I was going through section 36.3.1 ''SAI block diagram'' and ...
Posted on May 29, 2016 at 10:06hello. I make audio player on STM32F7-DISOC. I want to use SAI with DMA transfer. Using STM32CubeMX and stm32746g_discovery_audio.c of STM&sharp2CubeF7 and reffeing to Audio_playback_and_record project. SAI and DMA se...
Posted on January 07, 2016 at 18:24Hi,I've added SAI audio stream to a touchscreen app currently running on the STM32F7 Evaluation board.The screen has worked fine and I've been using DMA2D (ChromArt) to draw blended images quickly.However, now I've...
Posted on October 30, 2015 at 14:55Hi I am struggling to get the External Audio Clock Input (PC9 12.288MHZ) to be output by the SAI Master clock pin PF7. I have used STM32Cube to set it up and it all looks ok, but I can not get any output on the S...
Posted on October 29, 2015 at 10:56Hi,my friend, I want to implement the both TX/RX channel of SAI, but can not find any code sample in STM32CUBE. I want to use DMA to transfer audio data between SAI and codec and start the TX/RX DMA at once and jus...
Posted on August 23, 2015 at 01:24Hello Everyone.As the title suggest, I am trying to receive data from the two digital microphones that are on the STM32F7 discovery board. Since the microphones are connected to the audio codec, I need to interface ...

Posted on May 24, 2015 at 22:22Hi, I've been trying to use the SD_B output on an STM32F427VIT6 with no success. This is the 100 pin package. With typical SAI usage, SAI block B would not be usable since the MCLK, SCLK, and FS pins are on port F, w...
Posted on April 10, 2015 at 13:54Hi, i'm using SAI output on STM32F429BIT6. I used some of the code from STM32CubeF4-Example stm324x9i_eval_audio.c for initialization. In pricipal all works fine, but sometimes i get an Error from the SAI interface a...
