可以熟悉51单片机中断机制 大大方便学习51单片机

实时时钟芯片DS1302采用串行接口，只需3根引脚便可以完成操作，其使用非常方便。这里采用AT89S52单片机作为外部微处理器，来对DS1302进行控制-Real-time clock chip DS1302 serial interface, only three pins will be able to complete the operation, its use very convenient. AT89S52 microcontroller used here as an external microprocessor to control of the DS1302

LPC2119中UART异步串行通讯实例，该源码实现LPC2119的UART功能。-UART asynchronous serial communication in LPC2119 instance of the source code to achieve LPC2119" s UART functionality.

采用ATMEGA16驱动IC是PCF8533,对应LCD为NOIKA 6610,C语言格式。-ATmega16 driver IC is used PCF8533, the corresponding LCD for NOIKA 6610, C language format.

有关AVR单片机的bootloader，外国人写的，很实用，内容详细-the AVR MCU Bootloader, foreigners write, and very practical, detailed

这个是AVR的1602B字符型LCD模块-this is the AVR 1602B character LCD module

430单片机的部分源代码，读者可以适当的下载，自己看着办。-430 single-chip part of the source code, readers can download the appropriate,看着办own.

DAC1230是一个12位的模数转换的芯片!而使用时候是在8位的单片机上运行,所以需要注意高四位和低八位的写入时序-DAC1230 is a 12-bit analog-digital conversion chips! Use of time in the 8-bit single-chip run, so it is necessary to pay attention to the high four and low eight write timing
