Hi,i am using 2 units of STM32h743II MCU and I am trying to transfer I2C transactions from master to slave based on I2C_TwoBoards_ComPolling examples.data is received correctly each time but about my i2c slave unit perform Long clock stretching 1 out...

Hi,I am working with stm32H743II Board - which define SPI4 block as SPI Master according to the following:void MX_SPI4_Init(void) { /* USER CODE BEGIN SPI4_Init 0 */ /* USER CODE END SPI4_Init 0 */ /* USER CODE BEGIN SPI4_Init 1 */ /*...

ia m using STM32h743II MCU and I am trying to transfer SPI data from the spi4 block defined as SPI MASTER to the spi5 block defined as SPI SALVE without success using DMA.I'm looking for any basic example that actually works for transferring SPI payl...

Hi,I am working with 2 boards (stm32H743II) - one defined as SPI Master with SPI4 block and the other as SPI Slave with SPI5 block.I am trying to understand the balance between:# Init.DataSize configuration and Init.FifoThresholdcan someone give me s...

ia m using STM32h743II MCU and i am trying to transfer SPI data from spi4 block defined as SPI MASTER to spi5 block defined as SPI SALVE without success.I am using the HAL_SPI_Transmit from the SPI MASTER block (spi4 block) and HAL_SPI_Receive from t...

thank you for the answer.what do you mean by "continuous"?as you can see in the picture only the size of the payload is different.and for some reason, the first 8 bytes are "connected"

hi,what did you mean by "you can do this"?did you attach any files?

Hi,one chip loopback spi communication is for my debug - as you wrote my goal is a Full duplex between 2 different boards.but unfortunately did not succeed to write code using HAL_SPI_Transmit_DMAHAL_SPI_Receive_DMAorHAL_SPI_TransmitReceive_DMAthat i...

I can't find any example of SPI Com Polling that used the HAL_SPI_Transmit() and HAL_SPI_Receive() separately - all the examples I've seen are using HAL_SPI_TransmitReceive.can anyone refer to some examples using the HAL_SPI_Transmit() and HAL_SPI_R...

hi,thank you - I've added a semaphore but still HAL_SPI_Transmit() is sent successfully while HAL_SPI_Receive() returns HEL_ERROR.
