用AVR单片机实现的时钟芯片DS1302的SPI驱动，进行数据传输

低电压检测. A口低8位接键盘列线，键盘行线接VDDIO；B口高8位接LED // 按K1键 低电压为2.4v // 按K2键 低电压2.8v // 按K3键 低电压3.2v // 按K4键 低电压为3.6v

单片机控制122x32液晶。液晶内部芯片包含RAM（类似于显存），当然不具备2D3D加速。不过，功耗非常低，一般几个毫瓦。-SCM 122x32 LCD. LCD chip contains an internal RAM (similar to memory), of course, does not have to speed up 2D3D. However, power consumption is very low, generally a few milliwatts.

Power PC 55xx 主函数以及GPIO初始化-Power PC 55xx main function, as well as GPIO initialization

动态接口采用各数码管循环轮流显示的方法，当循环显示频率较高时，利用人眼的暂留特性，看不出闪烁显示现象，这种显示需要一个接口完成字形码的输出（字形选择），另一接口完成各数码管的轮流点亮（数位选择）。 -display
