PHILIP驱动器PCF8576驱动程序，可驱动4×40个点

该文档包含了keilc常用的子程序，共有２５个运算类代码，非常实用．-This document contains commonly used keilc subprogram, a total of 25 computing category code, very useful.

飞利浦RC522芯片源代码。该芯片主要针对三表市场和手持设备，支持I2C/SPI/UART接口。 先发布基于普通51单片机的驱动源代码，采用串口接口，无需中断。只要接一个串口，后续会发布基于飞利浦LPC9401的读写源代码！LPC9401也是基于51核，只需连接SPI接口！有公司拿这个源代码卖钱哟-Philips RC522 chip source. The chip targeted at three tables and handheld devices market, support I2C/SPI/UART interface. Based on the first general release 51 MCU-driven source code, using serial interface, without interruption. As long as a serial port access, the follow-up will be issued based on the Philips LPC9401 write source code! LPC9401 is based on the 51 nuclear, only connecting SPI interface! A company with the source code acquisition yo! !

可以将单片机与继电器以及温度传感器结合实现温度自动控制系统.例如可以用单片机显示温度传感器测到的温度,还可以在温度到达一定界限时控制继电器的通断以达到控制电路通断的效果.-Can be single-chip temperature sensor and relay, as well as realize automatic temperature control system combined. For example, we can use single-chip temperature sensor measured the temperature, but also the temperature has reached a certain limit of the on-off control relay control circuit in order to achieve on-off effect.

可以测试0~25V的直流电压，有软件滤波，和小数点自动进位功能.-Can test the 0 ~ 25V DC voltage, a software filter, and the decimal point automatic feed-bit functionality.
