At the moment, we evaluate feasibility of STM32H562 for our application. Our application is using PDM microphones. However, STM32H562 has SAI interfaces but no DFSDM filters.Is there any out of box application example /application note for PDM micro...
I am using the STM32H743 on STM32H743I-EVAL board.Is it possible to synchronize ADC acquisitions with the SAI block? The goal here is to acquire audio ADC samples using DMA, block process, and transmit out to a DAC over SAI using DMA. The STM32 is th...
I have a small problem if I use SAI DMA in circular mode, the first time it fills up the buffer, it works fine, but after it looks like it is the right data levels, but just that some are omitted.the top chart is DMA filling up the buffer, (first run...
Dear STM32 MCUs community,I am currently working on a project with the STM32l452RET6 MCU with a goal to use the SAI peripheral for one-directional single wire communication purposes, so only the "data line" (SD_A or SD_B) will be outputted using the ...
On the STM32 SAI peripheral, there's a member of the SAI_InitTypeDef which is: uint32_t OutputDrive; /*!< Specifies when SAI Block outputs are driven. This parameter can be a value of @ref SAI_Block_Outp...
Dear Sir.I use ICS-43434 connected to STM32U585 through SAI.The lines of the ICS-43434 SD,SCK,WS works fine ,But when the interrupt is enabled the program crash.Attached some code frgaments.Main.c.MX_SAI1_Init();static void MX_SAI1_Init(void){ /* USE...
Hello,what is the maximum input clock for the SAIs and I2Ss for the H7 ?I mean "sai_x_ker_ck" and "spi_ker_ck".I couldn't find it in neither RM nor DS.Is it dependent on some AHB / APB or D1/2/3 clock?98.304 MHz is working (it is also in the RM's exa...
I configured SAI1 asBlockA: I2S async slave transmitterBockB: I2S sync slave receivermanaging the data transfers with GPDMA1. The slave transmitter works fine, I get the half transfer and transfer complete interrupts correctly. But for the slave rece...
HI,After having configured the SAI PORT of the STM32L5 to communicate with a CODEC do you know how to recover the data ?Thank for your helps Regards
