IAR编译器下，使用ARM芯片，学习IIC通讯的好程序-IAR compiler, the use of ARM chips, a good learning IIC communication procedures

学习单片机最有用的恐怕是编程器和仿真机,一台商品化的编程器至少要几百元,仿真机价格更高,往往让初学者难以选择。这里介绍的一款国外电子网站推出的廉价51编程器，能够读写最常用的12种51单片机，自己动手装配一台，既能锻炼自己的动手能力,又能廉价地装备一台多用编程器，无论是学习单片机或业余时间搞开发，都是一个非常好的选择。笔者按照资料自制了一台，十分好用，不敢独享。特编译了全部制作资料介绍给大家。这个编程器硬件使用标准的TTL系列器件而没有使用特殊元件。它连接在计算机的并行端口，对PC的并口没有特殊要求，所以配置很低的计算机也能用这个编程器。Atmel Flash 系列单片机是当前最流行的单片机，易于擦写，不象OTP芯片容易造成浪费。特别是89系列单片机与大家熟悉的INTEL51系列单片机完全兼容，这个编程器支持的单片机主要是Atmel flash系列。-Single-chip learning is probably the most useful programming and simulation machine, a programmer commercialization of at least several hundred dollars, simulation machine prices higher, so that beginners are often difficult to choose. Here s a foreign site to launch low-cost e-51 programmer can read and write 12 types of most commonly used single-chip microcomputer 51, a do-it-yourself assembly, can exercise their practical ability, but also inexpensive to equip a multi-purpose programmer, whether it is free time to study or engage in the development of single-chip are a very good option.
