一个变频器的代码,用msp430就能实现.低成本,可靠性也不错.

此程序能实现PIC16F877A与D12实现USB通讯，能正确被主机识别-This process can realize PIC16F877A with D12 realize USB communications, were able to correctly identify the host

The sample software includes, common library, peripheral APIs, and test modules for the APIs. The common library include startup file, standard definition and header files, processor specific setup module, generic interrupt related APIs, timer routine, and scatter loading file. The peripheral directories include, GPIO, PWM, Real-time clock, timer, SPI, I2C, Watchdog timer, UART, external interrupt, etc.

51单片机编程说明，值得推荐，写的非常好的资料，与大家共享！-51 microcontroller programming note worthy of recommendation and write very good information, to share with you!

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.
