Build environment for the ICC-AVR6.3 using the ATmega8 chips, crystal rate of 6. 0000Mhz

51系列单片机实验课程：串口 （通过计算机与试验箱相连，互相收发信息）-51 Series single-chip experimental curriculum: serial (through the computer and the chamber connected to each other to send and receive information)

HT1621 是一款128 个位元的LCD 控制器件，内部RAM 直接对应LCD 的显示单元。相应的软件使它适用于包括LCD 模块和显示子系统在内的多功能应用。主控制器与HT1621 接口只需4 到5根线。内置的省电模式极大的降低了功耗。-HT1621 is a 128-bit LCD control devices, directly correspond to the internal RAM of the LCD display unit. The corresponding software to make it applicable to including LCD modules and display subsystems, including multi-purpose applications. Host controller interface with HT1621 only 4-5 lines. Built-in power-saving mode greatly reduces power consumption.

Using 16f876 & matrix led to show time.
