Guys,

I have a question for transmitting multiple bytes on STM32CubeMX, Can I make like this :

/* Send a data block fast */
static
void xmit_spi_multi (
uint8_t p[], /* Data block to be sent */
UINT cnt 
)
{
HAL_SPI_Transmit(&hspi2,p,cnt,100);
}

Thanks

Hi!

As long as the parameter

cnt

is never larger than the size of the buffer that

p

points to, that code will work.
