Hello!I am trying to configure Master clock output frequency for I2S interfacing with the TI tlv320aic3254 but there is no Master clock or i2s setting on the clock configuration.As i see in the Clock tree in the datasheet there are master clock optio...
on H743 board (DevEboard) I2S1 (master 16b 44k1) -> ES9038 DAC (I2S slave) : DAC playing music fine, ok. now switching DAC to I2S master , H743 to slave transmitter mode : no data / silence.test with DSO : pin PA7 (SDO) is tri state now! thats WRONG ...
I am trying to use the I2S2 interface in Master Rx mode with the Nucleo 401RE and X-Nucleo-CCA02M2 audio shield. I enable the SPI2 global interrupt in NVIC settings, setup the required GPIOs and generate the code. I want to receive data from the on-b...
Hi, I am trying to use a 4 I2s microphone. And I am using cubemx.I made work both of them with a sinple DMA transfer.I used I2s half duplex reciever 16of32bits sample rate 48Khz and DMA for 48*2 samples with uint16_t format. For that I used DMA1 str...
On a stm32 mcu, using HAL_I2S_Receive_DMA the clock generation is started. At first, the application went into a hard fault and nothing is subsequently written in the data receive buffer.HardFault_Handler:08000942: push {r7}08000944: add r7, sp,...
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...
project audio-player : sending data by DMA -> SPI/I2S to DAC :at first i read from SDcard (void bytes) as it is, to playbuffer, send it by circular DMA ("halfword") on I2S (16 bit) to DAC (as standard I2S 2 x 16 bit frames); working perfect.to use hi...
Hello Experts,I am working on i2s of stm32h743. The Manual says when the alignment is left the zeros are sifted from 0 to 7 in case of 24bit data length which is correct work but when I change the alignment right the zero does not appear on 24 to 31b...
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...
The stm32u5xx_hal_sai.c sets up the I2S clock strobing like this:static HAL_StatusTypeDef SAI_InitI2S(SAI_HandleTypeDef *hsai, uint32_t protocol, uint32_t datasize, uint32_t nbslot) { HAL_StatusTypeDef status = HAL_OK; hsai->Init.Protocol ...
