rc500 c语言库函数，对RC500的开发提供了捷径

一种实用的12864 液晶驱动程序，已经有实物验证 -12864 A practical liquid crystal driver, has been kind to verify

实验名称：看门狗实验 功能描述：使能系统看门狗。 如果将PA0连接到LED上观察到实验现象为LED灯闪烁。 如果连接到SPK上将会听到SPK间歇性鸣叫。 如果将watchdog_init() 注释掉或者将WDT_off() 前面的注释去掉则将看门狗禁止 此时连接到LED上观察到的现象为LED常亮 实验目的：熟悉看门狗的操作 实验说明：MCU--M16 外部7.3728M晶振 -AVR for Watchdog!

LPC2103的第二个实验：流水灯+按键，用proteus7仿真，C语言代码，在Keil3中编译，文件内已有完整的工程和仿真图了。-The second experiment LPC2103: water lamp+ button, and proteus7 simulation, C language code, compiled at Keil3 in the paper that has a complete map of the engineering and simulation.

4x4键盘的程序，新思路，希望能对大家有所帮助。-4x4 keyboard procedures, new ideas, hoping to be helpful for everyone.

基于ST7902驱动的12864LCD显示汉字、图片，显示自己做的字库汉字-ST7902-driven based on 12864LCD display Chinese characters, pictures, show the character of their own characters

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! !

51事例原代码 事例多多 应该对初学者很有用-51 examples of the original code examples should be more useful for beginners

网上找到的PCF8563程序基本不能用 本程序基于51单片机，模拟了I2C接口，现已调试成功，可以做成万年历了

高质量的18b20，显示非常清晰，而且使用1602显示，方便，实惠，值得推荐
