本系统以增强型51单片机STC12C5A60S2为控制核心,选用美国达拉斯公司生产的DS1302实时时钟芯片和DS18B20数字温度传感器制作了一个32×16点阵时钟。该点阵时钟通过较少的元器件实现了时间、温度、年、月、日、星期和重要节日轮流滚动显示功能,此外,用户还可以通过背面的三个触摸按键实现调时,同时系统还通过光敏电阻实现了感光功能。该系统制作完成后通过实物测试,获得了良好的效果。
The system to enhance the 51 single-chip microcomputer STC12C5A60S2 as the control center, the selection of the United States Dallas DS1302 real-time clock chip and DS18B20 digital temperature sensor produced a 32 × 16 dot matrix clock. The dot matrix clock with less components to achieve time, temperature, year, month, day, week and important holiday scroll display function, in addition, the user can also touch the button through the back of the tune to achieve, while the system also Through the photosensitive resistor to achieve the photosensitive function. After the system is manufactured, it has achieved good results through physical testing.
