I have set up a project in STM32CubeMX. I have setup both I2S1 for Receiving and I2S2 for Transmiting with DMA. After the normal initalization i start receiving from the DMA: if (HAL_I2S_Transmit_DMA(&hi2s2, (uint16_t*)&output_buffer, 1) != HAL...
I want to use STM32U5A5 SAI1 to generate via SAI1 a master I2S, with 24bit sample words.I need 24bit because sending out afterwards as S/PDIF (via SAI2) needs 24bit sample words (as I understand: SAI2 as S/PDIF Tx is "forced" to send as 24bit samples...
STM32F411. Line 2693: srcclk = __HAL_RCC_GET_I2S_SOURCE();That macro calls "READ_BIT" on the I2SSRC register bit.It does NOT shift it right 23U.The function then compares this to 0 or 1.FAIL.Result. I2S cannot be configured to use an external clo...
Posted on June 22, 2018 at 15:58There seem to be some bugs in the H7 HAL library.Firstly HAL_I2S_Receive_IT() causes a HardFault because, as far as I can see:1) OVR flag is not cleared2) in `HAL_I2S_IRQHandler()` there is an attempt to call ` hi2s->...
HiI am stuck with STM32H743IIT I2S DMA RX ..The code is working perfect when uncommet HAL_I2S_Transmit_DMA (Line 29) but when uncomment line 31 HAL_I2S_Receive_DMA it feedback HAL_OK but do never go into the callbacks ..What can be the issue ?Best re...
I am wanting to sample the MP45DT02 microphone data. I am very much a beginner with this but I have cobbled together some code from some examples. Any input as to why I am not able to see any data through the DMA would be greatly appreciated. DMA_In...
I was usig stm32f4 hal version 1.11 and in that version there was this code:void I2S_DMATxCplt(DMA_HandleTypeDef *hdma) { I2S_HandleTypeDef* hi2s = (I2S_HandleTypeDef*)((DMA_HandleTypeDef*)hdma)->Parent; if((hdma->Instance->CR & DMA_SxCR_CIRC)...
Hello!For a week i've been trying to configure my stm32f302cbt6 and the tlv320aic3254 codec to trasmit data to the mcu through i2s_ext_sd but HAL_I2S_Receive returns 0s to the buffer although i see data coming out of the codec. I have configured i2s2...
Greetings to the ST community,I was using the example project provided by ST in "STM32F769I-Discovery\Applications\Audio\Audio_playback_and_record\EWARM" and found out that voice was being output through the headphones. However I connected speakers t...
