[0055] The main control unit 1 is connected to the accelerometer gyroscope sensor module 2 and the LCD display module 3, and a Bluetooth module is provided in the main control unit 1.

[0056] This application does not limit the specific structure of the belt.

[0057] In this application, the external device can be a computer, mobile phone, or other device with communication capabilities. The displayed data can be weather, temperature, or other information sent by the external device.

[0058] In the above implementation, the belt is equipped with an LCD display module, a main control unit, and a Bluetooth module. The Bluetooth module can acquire various display data, which the user wearing the belt can obtain through the LCD display module. The belt also includes an accelerometer / gyroscope sensor module, whose data is transmitted to external devices via Bluetooth, enabling monitoring of the user's movement status.

[0059] Furthermore, the main control unit includes an FR8008GP chip; the Bluetooth module includes a Bluetooth receiving antenna; the Bluetooth receiving antenna is connected to the RF pin of the FR8008GP chip.

[0060] The FR8008GP supports BLE5.1 and is a 32-bit CPU with a 96MHz clock speed based on the Cortex-M3 core. It has a built-in 64Mbit Flash memory for storing user programs and data, and a built-in 2M bytes of PSRAM that can be used as a display cache.

[0061] For example, see Figure 2 This is a connection diagram for the FR8008GP chip. The RSTN pin is grounded through a capacitor; the DLDO-OUT pin is grounded through a capacitor; the VDDIO pin is grounded through a capacitor; the VBAT pin is connected to 3.3V; the BSW pin is grounded after connecting an inductor and a capacitor in series; the BFB pin is grounded through a capacitor; the RF pin is grounded through a capacitor; the 3.3V power supply is also grounded through a capacitor. The 24m-X1 pin is connected to the crystal oscillator circuit. The PD0 pin is connected to the VBUS power supply through a resistor; PC6 outputs a buzzer signal; PC7 is connected to the LCD reset signal, outputting the LCD_RST signal, which controls the LCD's reset; PA7 is connected to R11 to output the LED_PWM signal, which controls the LCD's backlight brightness; PB6 is connected to the LCD's TE signal, used to output the TE signal, which is used for LCD display data frame synchronization.

The first and second ends of the crystal oscillator are grounded through a capacitor. The third and fourth ends of the crystal oscillator are grounded.

[0063] See Figure 2 The PD7 pin of the FR8008GP chip is connected to a 3.3V power supply via a resistor.

[0064] Furthermore, the LCD display module includes an LCD display screen, which includes a display screen interface; the display screen interface is connected to the main control unit.

[0065] Furthermore, the accelerometer sensor module includes an MPU6050 chip.

[0068] SDA is the data of the I2C signal, SCL is the clock of the I2C signal, and INT is the interrupt I / O signal output by the MPU6050.

[0069] The MPU6050 is an integrated 6-axis motion tracking device. It integrates a 3-axis MEMS (Micro-Electro-Mechanical Systems) gyroscope, a 3-axis MEMS accelerometer, and a scalable DMP (Digital Motion Processor). It can connect to a third-party digital sensor via an I2C interface. The MPU6050 uses three 16-bit analog-to-digital converters (ADCs) for both the gyroscope and accelerometer to convert their measured analog signals into output digital signals. For accurate tracking of both fast and slow motion, the sensor's measurement range is user-controllable. The MPU6050 also includes an on-chip 1024-byte first-in-first-out queue, which helps reduce system power consumption. Communication with all device registers uses a 400kHz I2C interface or a 1MHz SPI interface (SPI is only available on the MPU-6000). For applications requiring high-speed transmission, register reads and interrupts can be performed using a 20MHz SPI. Additionally, a temperature sensor and an oscillator with only ±1% variation under operating conditions are embedded on-chip. The chip measures 4×4×0.9mm, uses a leadless square package, can withstand a maximum impact of 10000g, and has a programmable low-pass filter.

[0076] The SCL pin of the display interface is connected to the PB0 pin of the FR8008GP chip to transmit the clock signal of the QSPI signal.

[0077] The CS pin of the display interface is connected to the PB1 pin of the FR8008GP chip for QSPI signal enable signal control.

[0078] The RESET pin of the display interface is connected to the PC7 pin of the FR8008GP chip to control the reset signal of the LCD.

[0079] The TP_INT pin of the display interface is connected to the PA6 pin of the FR8008GP chip to receive the touch interrupt signal of the touch screen.

[0080] The TP_RST pin of the display interface is connected to the PD1 pin of the FR8008GP chip to control the reset signal of the touch screen.

[0081] The TP_SCL pin of the display interface is connected to the PD2 pin of the FR8008GP chip for the I2C clock signal.

[0082] The SDA pin of the display interface is connected to the PD3 pin of the FR8008GP chip for I2C data signals.

[0083] For example, see Figure 5 This is a connection diagram of the display interface. The NC pin is an empty pin on the interface socket and has no practical use; the GND pin is grounded; the LEDK pin is connected to the R7 resistor terminal and is the negative terminal of the backlight control circuit; the LEDA pin is the positive terminal of the backlight and is directly connected to the 3.3V power supply; the VCC pin is connected to the 3.3V power supply, which is also grounded through a capacitor; the IOVCC pin is connected to the VDDIO pin of the main control unit through an inductor; the IOVCC pin is also grounded through a capacitor.

[0084] As can be seen, in this application, the LCD display screen is driven by a 4-wire QSPI interface, which saves IO resources and wiring.

[0088] For example, see Figure 7 The diagram shows the debugging interface of this application. The debugging interface has pin 1 grounded, pin 2 connected to PA0 pin, and pin 3 connected to PA1 pin; pin 2 is also connected to a 3.3V power supply through a resistor.

[0089] Pins 1 and 2 are used to transmit relevant data during the debugging process. They are also used for later log maintenance and post-processing data management.

PA5 is connected to pin 2 of the USB interface via a resistor. Pins 2 and 3 are used to export main control unit data and perform software upgrades for the main control unit.
