Using SPI 3 wire with STM32L476 discovery Board

Posted by rbeal on 2016-11-01 10:39

Hi,

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

Here, the main function :
codeQuestion

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

The LSM reply 0xff one hit and 0x00 the two next hits.
Is this the LSM reply or STM32 error?

I have added these lines :

HAL_SPI_MspDeInit(&hspi2);
HAL_SPI_MspInit(&hspi2);


But it still not working.
