The controller model in this example is chinaware CA51F253L 3. CA51F253L3 is an 8-bit microcontroller based on a 1T 8051 core, and generally, the operating speed is 10 times faster than that of a conventional 8051 chip, and the performance is more excellent. The built-in 32KFlash program memory has the characteristic of repeated programming for many times and has better anti-interference performance. The clock source of the RTC module is provided by a high-precision 32.768KHz crystal oscillator.

The scale indicating lamp is an RGB LED lamp; the dial plate is provided with a light guide sheet corresponding to each scale indicator lamp; the dial plate is the ring form, and the scale pilot lamp is 60, and the scale pilot lamp is the circumference shape evenly distributed on the dial plate.

The power supply system comprises a main power supply module and an RTC button cell. As shown in figure 1, the main power supply module supplies power for 5VDC, has a reverse connection prevention function and is just connected with a 5VDC USB connector on the market. Under the condition of the power-off of the main power supply module, the RTC button cell supplies power to the RTC module continuously, so that the normal work of the RTC module is ensured, the function that time information is not lost is achieved, and when the main power supply module works, the RTC button cell does not discharge, so that the higher use efficiency of the RTC button cell is ensured.

The driving circuit modules are arranged into six groups, and each group of driving circuit modules drives ten scale indicating lamps; the drive circuit module comprises a triode, an I/O port of the controller is connected with a base electrode of the triode, an emitting electrode of the triode is connected with the positive electrode of the power supply system, and a scale indicator lamp is connected between a collector electrode of the triode and the I/O port of the controller in series. The driving circuit module adopts a matrix control mode to control the on-off and the brightness of the scale indicating lamp. As shown in fig. 2, in the present embodiment, an S8550 transistor is used, and the scale indicator is driven by using the current amplification characteristic of the S8550 transistor, so as to adjust the brightness of the scale indicator. When the triode emission is at high voltage, if the triode collector is high voltage, then be off-state between triode base and the triode collector, the scale pilot lamp goes out, if the triode collector is low voltage, then triode base and triode collector switch on, at this moment, the controller IO mouth output low level that the corresponding seg end of scale pilot lamp that needs to turn on was connected, and the corresponding colour diode of scale pilot lamp is turned on, realizes the effect of switch.
