AVR单片机实现SPI通信完整源码,可直接拿过来用了

多种实时时钟芯片的读写应用程序，所用控制器为MCS-51系列的单片机-multiple real-time clock chip to read and write applications, using controller for the MCS-51 microcontroller series

用C51开发的单片机多机通讯程序，其中包括双口RAM的读写程序。 这个程序调试通过，应用在我开发的系统中，效果很好。-C51 Microcontroller with the development of multi-machine communication procedures, including dual-port RAM reading and writing process. Debugging through this process, the application in my development system, good results.

介绍了一种利用定时中断为单片机编写高音准的音乐程序的方法，并给出实例程序清单。-introduces a timer interrupt to the microcontroller prepared Treble-music approach procedures, and gives a list of examples.

温度控制器V1.5 显示为三个共阳极LED 温度传感器用单总线DS18B20 CPU为2051，四个按键，分别为UP，DOWN，SET 温度调节上限为125度，下限为-55度 只能用于单只18B20-Temperature Controller V1.5 show for a total of three LED anode temperature sensor with single CPU for the bus DS18B20 2051, four keys, respectively UP, DOWN, SET temperature regulator ceiling of 125 degrees and lower limits of-55 degrees can only be used solely 18B20

主要是实现I2C协议的一种方法，主要运行环境是ADS1.2-I2C protocol is mainly to achieve a method, the main operating environment is ADS1.2
