此投票机被设计为四个候选人。通过四个触觉开关提供了提供的投决定票。这些交换机从用户手动输入并将它们传输到控制器的针脚。基于这些投入，为不同的候选人投票计数增加由 AT89C51. 显示计票，四个七段显示也连接到微控制器 （请参阅与 AT89C51 的交互的七段)。每个候选人的计数值是发送到相应的部分。四项罪名连续出现的多路复用 这些网段通过 AT89C51。

L298N是ST公司生产的一种高电压、大电流电机驱动芯片。该芯片采用15脚封装。主要特点是：工作电压高，最高工作电压可达46V；输出电流大，瞬间峰值电流可达3A，持续工作电流为2A；额定功率25W。内含两个H桥的高电压大电流全桥式驱动器，可以用来驱动直流电动机和步进电动机、继电器线圈等感性负载；采用标准逻辑电平信号控制；具有两个使能控制端，在不受输入信号影响的情况下允许或禁止器件工作有一个逻辑电源输入端，使内部逻辑电路部分在低电压下工作；可以外接检测电阻，将变化量反馈给控制电路。使用L298N芯片驱动电机，该芯片可以驱动一台两相步进电机或四相步进电机，也可以驱动两台直流电机。-L298N is produced by ST a high-voltage, high current motor driver chip. The chip uses 15-pin package. Main features are: high voltage, the maximum working voltage up to 46V output current, instantaneous peak current up to 3A, continuous operating current of 2A rated power of 25W. Contains two H-bridge high-voltage high-current full-bridge driver can be used to drive DC motors and stepper motors, relay coils and other inductive load using standard logic level signal control has two enable control terminal, input signal without affecting the case to permit or prohibit the device work a logic supply input, so that part of the internal logic circuits at low voltage work can be an external sense res

资源描述This application note shows how to control a permanent magnet synchronous motor (PMSM) with the sensorless field-oriented control (FOC) algorithm, using an ARM® Cortex®-M0-based PSoC 4 device. The FOC algorithm is frequently used in motor control applications because it allows motors to operate with less noise and more stable torque output than other algorithms. Sensorless FOC adds the advantage of reducing the cost due to the absence of rotor position sensors. Sensorless FOC is used in many applications including consumer (air conditioner, refrigerator), industrial (blower, pump), and commercial (elevator, escalator) products.
