用PCF8593时钟芯片和MAX7219的LED驱动芯片联合制作的基于AT89C51单片机的电子时钟。

包括两部分：

1.仿真部分，用的是Proteus电子电路仿真软件，版本7.1Sp4。

2.软件部分包括PCF8593时钟芯片的驱动，MAX7219芯片的驱动，编译环境为Keil-PCF8593 clock with the LED chip and MAX7219 chip drivers to co-produce AT89C51 single-chip microcomputer-based electronic clock. Consists of two parts: 1. The simulation part of the Proteus with the electronic circuit simulation software, version 7.1Sp4. 2. Software includes driver PCF8593 clock chip, MAX7219 driver chip, the compiler environment Keil
