Hello everyone I am trying to interface acceleration sensor Adxl345 to stm32f302 through I2C  using the HAL Library. Actually I am learning the programming , does any one help me how to get the data from sensor. I wrote this code , it does not work it. 



void adxl345_data(void)

uint8_t data[2];
int x ;
int data_1;
char buff[100];

HAL_I2C_Mem_Read(&hi2c3, 0x53<<1, 0x32, I2C_MEMADD_SIZE_8BIT, (uint8_t*)data, 2, 1000);

x = ( data[1]<<8) |data[0];




could you give me idea where is mistake ?
