There is a problem with the angle output with the acceleration sensor.

Hello,

I got the acceleration value using mpu6050 sensor. And I am going to use this to get the angle of the sensor.
The formula below has shown that angles can be obtained.

                //Angle formula_1
                /*float RADIAN_TO_DEGREES = 180/3.14139;
                float val_x = atan(accel_values.y/sqrt(pow(accel_values.x,2) + pow(accel_values.z,2))) * RADIAN_TO_DEGREES; //X slope
                float val_y = atan(accel_values.x/sqrt(pow(accel_values.y,2) + pow(accel_values.z,2))) * RADIAN_TO_DEGREES; //Y slope*/

                //Angle formulal_2
                float pitch = atan(accel_values.x / sqrt(accel_values.y^2+accel_values.z^2));
                float roll = atan(accel_values.y/ sqrt(accel_values.x^2+ accel_values.z^2));

                //NRF_LOG_INFO("Accel : %d, %d, %d", accel_values.x, accel_values.y, accel_values.z);
                //NRF_LOG_INFO("Gyro : %d, %d, %d", gyro_values.x, gyro_values.y, gyro_values.z);
                NRF_LOG_INFO("X-Angle : %f", pitch);
                NRF_LOG_INFO("Y-Angle : %f", roll);

However, as shown in the image below, the value does not appear and is output as blank.

                            

Can you tell me what's wrong?

Thank you.

Hi,

NRF_LOG macros does not support the "%f" float format specifier. Instead, you should use the following as specified in the logger documentation:

NRF_LOG_INFO("float value:" NRF_LOG_FLOAT_MARKER "\r\n", NRF_LOG_FLOAT(val));

Best regards,
Jørgen

Hello,  Jorgen Holmefjord.

I'm asking because I have another problem with proceeding with this.
The float variable, the angular value of the sensor, is output, but only zero. I tried debugging, but I couldn't find any problems. Can I know about this problem?

Thank you.
