51系列单片机读卡程序，本人亲测，适合考勤、门禁。

系统讲解了51单片机,实用于初学者,可以很快入门-system on the 51 microcontroller, in the practical and beginners can quickly entry

51单片机ADS7846/ADS7843芯片驱动，适合用在4线制触摸屏，它通过标准SPI协议和CPU通信，操作简单，精度高。-51 ADS7846/ADS7843 chip microcontroller-driven and is suitable for use in the 4-wire Touchscreen, SPI through standard protocols and CPU communication, simple operation and high accuracy.

该程序实现有两个单片机进行环境温度和关照信息的采集。-The program has two microcontrollers to achieve environmental temperature and care information collection.

51单片机的端口应用，绝对能用的，直接是开发板的程序，来下吧-51 port MCU applications, the absolute can be used, direct the development of board process to the next bar

采用ADC0809采集数据，并通过串口上传到上位机，采用C语言编写，简单易懂-using data acquisition, and through serial upload it to the PC using C language. easily understood

avr串口实验,并且带有硬件原理图，程序简单，适合新手！-avr serial experiments, as well as with the hardware schematic diagram, a simple, suitable for novice!
