e systick. Then the SystemClock_Config() function is used to configure the system clock (SYSCLK) to run at 250 MHz.</p>
<p>The SPI peripheral configuration is ensured by the HAL_SPI_Init() function. This later is calling the HAL_SPI_MspInit()function which core is implementing the configuration of the needed SPI resources according to the used hardware (CLOCK &amp; GPIO). You may update this function to change SPI configuration. The Full-Duplex SPI transfer (16bit) is done using LL Driver functions LL_SPI_T
