We want to use HAL_SPI_Transmit to send data (master) in 8-bit units.However, even though we have set SPI_DATASIZE_8BIT, data is sent in 16 bits.Is there anything incorrect in the code below? uint8_t *spi_txdata;spi_txdata = (uint8_t *)malloc(2 * siz...

I have a question regarding interrupt handling for CDC_Receive_FS.After receiving CDC_Receive_FS we do any process we created, but we do not want to do CDC_Receive_FS during the process.Is there an API to disable or enable CDC_Receive_FS interrupts?

This is a question regarding virtual COM port communication using CDC.A STM32F412 Discovery with CDC installed is connected to a Windows PC, and 70 bytes of data is sent from the PC via serial communication.However, when receiving with CDC_Receive_FS...

We are trying to add built-in self-test capability to a program we are developing.Specifically, we would like to periodically check ROM and RAM. Are there any sample programs for those? [MCU] STM32F412VGT6

This question is about SPI simplex communication.Is there any sample code that realizes SPI simplex communication only by register operations?Also, is there any sample code that uses HAL or LL?I would like to know both cases of sending and receiving....
