accelerometer_result_error

[Nero]

Hello ,I wrote a program that allows to control the LIS2DE12 accelerometer but I am reviewing a fixed result which is always X = 72, Y = 33, Z = 32, I find out where the problem , thanks you in advance.

`int main(void)	
{
	int8_t X,Y,Z;
    
    uart_config();
    
    //accel_I2C_datawrite(&twi_instance);
    twi_init();
     m_device_address = accel_addr;
 
    uint8_t rx_buffer[6];
   rx_buffer[0] = 0x00;
//int threshold;
//accel_set_threshold(threshold);
    
        




            while(true)
        {
            accel_xyz_read(&X,&Y,&Z);
         printf("Groupeer accelero DATA2:  X: %d  Y: %d  Z: %d  \n", X ,Y,Z);
					nrf_delay_ms(1000);
        }      
    
}
`

Here is the code I used

ret_code_t accel_I2C_datawrite(const nrf_drv_twi_t * p_twi_instance)

{ nrf_drv_twi_enable(p_twi_instance);
ret_code_t ret_code
uint8_t tx_data1[2] = {CTRL_REG1, 0x00}; ret_code = accel_I2C_register_write(accel_addr, tx_data1, sizeof(tx_data1) ); nrf_delay_ms(10);

    return ret_code;

}

ret_code_t accel_I2C_register_read(uint8_t slave_addr, uint8_t reg_addr, uint8_t * pdata, uint32_t bytes) {
ret_code_t ret_code; ret_code = nrf_drv_twi_tx(p_twi_master,slave_addr, &reg_addr,1,false);

if(ret_code != NRF_SUCCESS)
{
 
        return ret_code;
}

ret_code = nrf_drv_twi_rx(p_twi_master,slave_addr, pdata, bytes);

return ret_code;

}

static void accel_xyz_read(uint16_t * x_value, uint16_t * y_value, uint16_t * z_value) { m_device_address = accel_addr; ret_code_t ret_code;

uint8_t rx_buffer[6];
rx_buffer[0] = 0x00;

ret_code = accel_I2C_register_read(m_device_address,access_data, rx_buffer, sizeof(rx_buffer));

*x_value = (rx_buffer[1]<<8)|rx_buffer[0]; *y_value = (rx_buffer[3]<<8)|rx_buffer[2]; *z_value = (rx_buffer[5]<<8)|rx_buffer[4]; //return ret_code; }

int accel_set_threshold(int threshold) { int max_threshold = 127* THS_2G ; uint8_t ths = threshold/THS_2G; uint8_t accel_reg[2]; printf( "hors threshold \n"); if (threshold > max_threshold) { printf( "Threshold out of range\n"); return -1; }

accel_reg[0] = INT2_THS;

accel_reg[1] = ths;

accel_I2C_register_write(accel_addr,accel_reg, sizeof(accel_reg) );
accel_I2C_register_read(m_device_address,INT2_THS, &ths ,sizeof(ths));



printf ("Threshold @%x(%d)\n",ths, ths);

return 0;

} int main(void) { uint16_t X,Y,Z; nrf_gpio_cfg_output(LED_1); nrf_gpio_pin_set(LED_1); uart_config(); printf("Start"); //accel_I2C_datawrite(&twi_instance); twi_init(); // m_device_address = accel_addr;

uint8_t rx_buffer[6]; rx_buffer[0] = 0x00;
accel_xyz_read(&X,&Y,&Z); printf("Groupeer accelero DATA: X: %d Y: %d Z: %d \n", X ,Y,Z);

        while(true)
    {
	int threshold;

accel_set_threshold(threshold); // accel_xyz_read(&X,&Y,&Z); // printf("Groupeer accelero DATA2: X: %d Y: %d Z: %d \n", X ,Y,Z); nrf_delay_ms(100); }
