Guys,

How can I control SPI1 hardware NSS output  (PA4) ?
I tried to give a signal to it, but nothing on my logic analyzer...

#define Mp3SelectControl()      { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4 , 0 ); }
#define Mp3DeselectControl()    { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_4 , 1 ); }
 
.
.
.
                Mp3SelectControl();
        HAL_Delay(10);
        Mp3DeselectControl();
        HAL_Delay(10);

Any clues ? thanks
