WHY I cant use HAL_SPI_Transmit outside of the main function.

[SKAŞ.1]

Hello Folks,

my initial goal is now to create a library. I have to use the SPI function outside of main.c file. However, I cannot make HAL_SPI_Transmit function run outside of main.c file. Also, I cannot able to run outside of main function inside the main.c

It goes into HardFault_Handler

 

I didn't do anything crazy, here is my full program too.

I should be able to use these functions outside the main function right?

Kind regards.

You can use it, you just need to use it correctly.
