Hi,

Since some days, i try to use SPI with my discovery board.

Here, the main function :
code

I have this error : HAL_SPI_STATE_BUSY_TX at line 156.

I try to initialize the LSM303CTR which i have one the board.
I can’t debug SPI because there is no output of this... The wire go under the screen and i can’t watch it with mesuring device.

I don’t know if i should initialize GPIO for SPI. I try to understand codes from demo projects but there are more than 100 files and this is maybe too hight level for me.

Usually, i work with PIC, STM32 appears more hard.

Best regards,
rbeal
