美国TI公司的protel 元器件库，在应用中需要更新，本人收集了最新的版本共30M，为提高上传速度分六次上传。文件名依次为TI_1到TI_6。希望大家设计电路板时少走弯路 以下是TI_5-TI" s U.S. Treasury protel components, need to be updated in the application, I collected a total of up-to-date version of 30M, to improve the upload speed upload six hours. File name followed by TI_1 to TI_6. Hope that the design of circuit board is less detours following TI_5

三相步进电机的三相六拍工作方式，正转的绕组通电顺序：A、AB、B、BC、C、CA、A，反转的通电顺序：A、AC、C、CB、B、BA、B、A。 由于步进电机转子有一定的惯性以及所带负载的惯性，故步进电机的工作过程中不能及时的启动和停止，在启动时应慢慢的加速到预定速度，在停止前应逐渐减速到停止，否则，将产生失步现象。 步进电机的控制问题可总结为两点： 1、产生工作方式需要的时序脉冲； 2、控制步进电机的速度，使它始终遵循加速、匀速、减速的规律工作。 -Three-phase three-phase stepper motor six shot work, is to order the winding power: A, AB, B, BC, C, CA, A, reverse the order of power: A, AC, C, CB, B, BA, B, A. As the stepper motor rotor has a certain degree of inertia, as well as brought about by the inertia load, the stepper motor during the course of work should not start and stop time, start to be slowly accelerated to a predetermined speed, the stop should be to slow down gradually to the stop, otherwise, will result in out-of-step phenomenon. Stepper motor control problems can be summarized in two points: one, resulting in the need to work the timing pulse 2, control the speed of stepper motor, so that it always followed acceleration, velocity, deceleration of the law of the work.

单片机音乐 音乐编程 通过蜂鸣器发出讯响 只要通过修改 后面的音乐程序里面的码 表就可以自己谱曲唱歌！ 前一个参数为按照编码表给定，第二个参数为节拍数 -MCS Music music programming through the buzzer sounded after hearing sound of music as long as the procedure by modifying the code inside the table you can compose their own singing! Before a parameter is given in accordance with code table, and the second parameter is the number of beats
