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.

边界扫描技术越来越重要了，这大家都明白，但它是如何工作（原理）的呢？想必不是每一个人都明白的。现在这个能帮助大家学习边界扫描。- The boundary scanning technology has been more and more important, this everybody understood, how but is it works (principle)? Thought is not each people all understands. Now this can help everybody to study the boundary scanning.

1.序列COM通讯的源代码。2.TCP/ IP通信的源代码。通过实施VC6.0

这是一个简单的例子，基于 8051 单片机的电子密码锁。该示例项目还描述了如何接口 16 × 2 液晶显示器和键盘。简单的电话键盘用于此项目。系统启动时最初"输入密码"在第 1 行上显示和用户输入密码，并在每个键按下 * 在屏幕上显示。此密码是 4 位数长度。如果输入 4 位数密码匹配用在程序代码中的预定义密码后然后系统激活锁定继电器连接在引脚 # 0 的端口 P2 意味着打开锁，并显示用户锁被打开一条消息。现在关于紧迫 " *" 关键用户可以再次启用锁定。如果是不正确的密码然后系统显示无效的密码的消息，并不能打开锁。在代码中定义的锁的密码是"1234″。如果用户输入错误的关键，并想要从开始再次输入密码，然后用户可以按 " *" 中重新输入密码。

本程序介绍了基于NIOSii的串口接收程序-This procedure based on the introduction of the serial receive procedure NIOSii
