Hello. I have troubles with connecting adxl345 to stm32f103vet6.

When I try to read a data from device, I always get '0'. For example:

int16_vect3 myVec;

ADXL_GetACC(myVec);

///myVec.x now is '0', myVec.y=0,myVec.z=0I'm sure that I connect and initialize the accelerometer properly - http://pastebin.com/T4fuArEr #spi #stm32 #adxl345

Be sure you enable the clocks for GPIOA and SPI1, before configuring the peripherals.

You initialize some pins for SPI2 Set the pins as AF_PP, the peripheral will control the direction/use based on 2wire and Master/Slave settings.   /* Configure SPI1 pins: SCK, MISO and MOSI ----------------------------*/   GPIO_InitStructure.GPIO_Pin = GPIO_Pin_5 | GPIO_Pin_6 | GPIO_Pin_7;   GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;   GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF_PP;   GPIO_Init(GPIOA, &GPIO_InitStructure);

If I doing it how you say  ADXL_SPI_Setup()!=Success

And now I can't initizalize, but few days ago all was be ok.

I decided to use I2C connection and all is ok.
