用两块51单片机基于RS232实现单片机之间的串行通信。又从机检测到当地温度，然后由主机查询，从从机读得温度数据。该程序时C51程序。-MCU with 2 RS232-based serial communication between the SCM. And from machine to detect the local temperature, and then by the host queries, from the temperature data from the machine-readable too. The program C51 program.

这是单片机C51的各种代码包，包括：I2C应用程序、滚动码应用原程序、红外应用源程序集、用计算机并口模拟SPI通讯的C源程序-C51 microcontroller This is the code, including : I2C applications, rolling code original application procedures, Application of infrared source sets, computer simulation of SPI communications Parallel C source files, etc.

这是f040与2401连接后，进行通信的程序。已经调试通过了 仅供大家参考 第一次传 不好的习惯请大家指正 -This is connected with the 2401, the communications procedures. Debugging has been adopted only refer to the first-bad habit of correcting Thank you, please

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.
