Hello, I'm high school student(not good at English...), very interested in STM32 board. 

I'm studying about SPI using STMCubeMX, and I know there is HAL_SPI_Transmit function.

But I couldn't understand about 'Timeout' argument which is one of the arguments of this function. So, Could you explain what does 'Timeout' means and Why Timeout are used?
