* 1. Introduction to project functions
    This project uses Renesas' R7FA2E1A72DFL model MCU to display time using a 0.56-inch common cathode red digital tube, can manually calibrate the time, and uses the AHT20 chip to measure and display temperature and humidity.
    The functions of the four buttons are as follows:
     1. Long press sw3 to switch modes, 0: normal display 1: modify hours 2: modify minutes 3: save the modified data.
        Each time the mode is switched, the buzzer will sound and the corresponding position will flash.
      2. Long press sw4 to reduce time. Each time the value is modified, the buzzer will sound.
      3. Long press sw5 to add time. Each time the value is modified, the buzzer will sound.
      4. Long press sw6 to enter the temperature and humidity display mode. The first two digits display humidity and the last two digits display temperature. The temperature and humidity are read every 2s. When sw6 is released, it returns to normal display.
    The actual picture is as follows:
     * 2. The project attributes
   are disclosed for the first time; the project is original;
* 3. Open source agreement
* 4. Hardware part The
  hardware mainly includes the power supply part, MCU main control, input and output devices, and control interface. The four parts
  are mainly the same as the open source project, except that the digital tube was bought incorrectly
* 5. Software part
  Since the digital tube is different from the open source project, the driver code is modified again, as follows: This function displays the j value timer interrupt
  at position i * 6. BOM list * 7. Competition LOGO verification * 8. Demonstrate your project and record it into a video and upload it.       Please see the attached mp4 video
