More specifically, the embodiment provides a specific calculation example:
In the space coordinate system, each axis of X, Y, and Z is perpendicular to the three directions of the dice. The vector R is the vector detected by the accelerometer, which is the result of the inertial force in the example above.
RX, RY, RZ are the projections of the vector Ron X-axis, Y-axis, and Z-axis.
Note the following relationships:
R

2 (Formula 1)
This formula 1 is equivalent to the three-dimensional space Pythagorean theorem. The digital accelerometer can obtain information through I2C, SPI or USART, while the output of the analog accelerometer is a voltage value within a predetermined range, which needs to be converted into a digital value with an ADC (analog to digital) module. For example, the output value of a 10-bit ADC module ranges from 0 to 1023.
Supposing that the following three axes of data are obtained from the 10-bit ADC module:
AdcRx=208;
AdcRy=485;
AdcRz=865;
Each ADC module has a reference voltage, assuming that it is 3.3V. To convert a 10-bit ADC value to a voltage value, the following formula is used:
VR x=AdcRx*VR/1023
Substitute the values of the 3 axes into the above formula to get:
VRx=208*3.3/1023=0.671V
VRy=485*3.3/1023=1.565V
VRz=865*3.3/1023=2.790V
Each accelerometer has a voltage value of zero acceleration, which corresponds to an acceleration of 0 g. A signed voltage value can be obtained by calculating the offset from the 0 g voltage. For example, the 0 g voltage value V0 g=1.650V, the offset relative to the 0 g voltage can be obtained in the following way:
DVRx=0.671V−1.650V=−0.979V
DVRy=1.565V−1.65V=−0.085V
DVRz=2.790V−1.65V=1.140V
The final conversion also needs to introduce the sensitivity of the accelerometer, usually in mV/g. For example, the sensitivity of the accelerometer is Sensitivity=500 mV/g=0.5 V/g. To get the final acceleration in g, the following formula is used:
R
X=DVRx/Sensitivity
R
X=−0.979V/0.5V/G=−1.958 g
R
Y=−0.085V/0.5V/G=−0.17 g
R
Z=1.140V/0.5V/G=2.28 g
R
x=(AdcRx*VR/1023−V0G)/Sensitivity (Formula 2)
R
y=(AdcRy*VR/1023−V0G)/Sensitivity
R
z=(AdcRz*VR/1023−V0G)/Sensitivity
Now the three components of the inertial force vector are obtained, and the device is not affected by any external force except gravity, it can be considered that this direction is the direction of the gravity vector. If you want to calculate the inclination of the device relative to the ground, you can calculate the angle between this vector and the Z axis. This result can be divided into two components: the inclination of the X-axis and the Y-axis, which can be obtained by calculating the angle between the gravity vector and the X and Y-axes.
The required angle is the angle between the vector R and the X, Y, Z axes, then taking these angles as Axr, Ayr, Azr.
cos (Axr)=Rx/R, similarity:
cos (Ayr)=Ry/R
cos (Azr)=Rz/R
From formula 1, it can be deduced that R=SQRT (Rx2+Ry2+Rz2)
The required angle can be calculated by the arccos ( ) function:
Axr=arccos (Rx/R)
Ayr=arccos (Ry/R)
Azr=arccos (Rz/R)
The accelerometer will indicate the direction of the XZY axes corresponding to the physical chip 50 or device.
The following example is used to determine that the output of the accelerometer corresponds to RateAxz.
First keep the device level. The XY axes output of the accelerometer will be a zero acceleration voltage.
Rotate the device around the Y-axis, at this time, the acceleration output values of X and Z axis will change while that of the Y-axis remains unchanged.
When rotating the device at a constant speed, observe which channel of the accelerometer changes the output value, other outputs should remain unchanged.
When the accelerometer rotates around the Y axis, the channel where the output value changes is AdcGyroXZ, which is used to calculate RateAxz.
As the final step, confirm whether the RateAxz value needs to be reversed.
Repeat the test above, rotating the device around the Y axis.
The same method can be used to test RateAy: by rotating the device around the X axis, you can measure which output of the totalizer corresponds to RateAyz and whether it needs to be reversed. Once InvertAyz is determined, RateAyz can be calculated using the following formula:
RateAyz=InvertAyz*(AdcGyroYZ*VR/1023−VzeroRate)/Sensitivity
Based on the above algorithm, static gravitational acceleration can be measured in tilt detection applications. The device offers several special detection functions. The activity and inactivity detection function detects the presence or absence of motion by comparing the acceleration on any axis with a set threshold. The tap detection function can detect single and double vibrations in any direction. Free fall detection can detect if the device is falling. These functions can be independently mapped to one of the two interrupt output pins. Therefore, all directions of the dice can be detected at all times, and then wirelessly transmitted to the user's mobile phone.
The embodiment further provides a computer readable storage medium 300, which stores computer programs. When the computer program is executed by the processor 420, the processor 420 executes the above calculation method of the figures of the intelligent dice 100.
The embodiment further provides a chip 50, comprising a memory 410 and a processor 420. The memory 410 stores computer programs. When the computer program is executed by the processor 420, the processor 420 executes the above calculation method of the figures of the intelligent dice 100.
