#The7thLiChuangElectricityContest#Real-time posture display

1. The real-time attitude display adds the function of LED indication on the basis of the official case, that is, the number of LED lights increases with the increase of the tilt angle of MPU6050,
   so that the tilt attitude of the attitude display can be clearly understood. 
 
2. I found that when the attitude is displayed on the OLED using the official code, the pitch value will be offset by about 30 degrees, and then I corrected it in the simplest way. After correction, it is placed on a plane and
   displayed at about 0 degrees, as shown in the figure
         
3. The figure below defines the proportional coefficient of the inclination of the three axes XYZ. The coefficient can be adjusted according to the inclination angle of the attitude so that
the number . The larger the value, the less sensitive it is. It is recommended to be between 1 and 11.
 
4. You can understand it by looking at the program and comments in the figure below. It is simple.
 
5. When I sent data through the serial port for these two lines of code, the computer displayed garbled characters. The baud rate, stop bit, word length, etc. were all set to the same as the program, but it was still garbled
  . The reason is unknown, so I simply commented it out.
 
6. The attached video demonstrates the operation of initializing MPU6050. After pressing the reset button, you need to tilt it about 45 degrees and wait for a few seconds for the initialization to complete.
