Guys,

I want to send a command and then retrieve the output on MOSI line ... Is the right way doing it ?

int resultvalue = 0;
uint8_t data7[2] = { VS_READ_COMMAND, addressbyte };
HAL_SPI_Transmit(&hspi1,data7,2,1000);
then :
uint8_t data8[1] = {0x00}; <=== is it declared properly ?
resultvalue = HAL_SPI_Receive(&hspi1,data8,1,1000);
resultvalue <<= 8;
resultvalue += HAL_SPI_Receive(&hspi1,data8,1,1000);
return resultvalue;

Thanks a lot

I calculate :

34832

(decimal) = 0x8810(hex)... So it's doing the job correctly ( SPI bus ) .... Why isn't working yet ??

Does SPI speed matter ?
