What is the proper way to send hex characters using HAL_SPI_Transmit?
New to STM32s and somewhat new to C and I need a bit of advice.I am trying to send different number of hex characters to the SPI interface.I have used HAL_SPI_Transmit (&hspi1, (0xB8, 0x03, 0x00),3, 100);however, I get errors. I cannot use variables...
