MSP430 我们全国电子竞赛老师给的资料(MSP430 National Electronic contest teacher gave us the information)

lcd1602单片机万年历，不开多得的好资料，你看了肯定不会后悔。(Beginners lcd1602)

这是关于电路板的设计图，方便大家下载。呵呵 (This is about the second Five-Year Plan, said a key project for the future development of a box of reference )

OS_II移植到单片机,网上都是大模式移植,这是我在网站上找到的小模式移植,不知道有用吗?(OS_II transplanted into single-chip, on-line model of graft are large, this is my website found in the small model of transplantation, I do not know useful?)

vb单片机上位机例程 很详细的例子，直接可用 适合初学者 (vb example)

频率相位测量的程序。实现相位差的测量与显示。(Frequency phase measurement process. Implementation phase of the measurement and display.)

基于RS485的简单现场总线通信系统设计，功能如下：单发单收，在发送状态，能够连续发送从0到99的数字； 单发单收，在接收状态，能够接收数据，并在数码管上正确地显示出来； 单发多收，在AB完成的基础上，接上多个接收设备，能够正确发送和接收； (Based on a simple RS485 field bus communication system design, the following functions: single single collection, sending state, can be continuously transmitted from 0 to 99 single single collection, in the receiving state, capable of receiving data and digital tube correctly displayed single overcharged, on the basis of completion of the AB, connected to multiple receivers, can correctly send and receive )

基于 AVR 单片机的水温自动控制系统 摘要: 本系统以 ATMEGA16 单片机作为系统的检测和控制核心，采用温度传感器 AD590实现0—100℃温度范围内的实时温度采集，通过双向可控硅 BT136 控制电热杯对系统进行加热，利用继电器控制半导体制冷片对系统进行散热。通过一线键盘实现对任意温度值进行设定并对模糊 PID 参数的调整，液晶 LCD1602 实时更新显示当前温度测量值与键盘设定温度值。利用模糊 PID 算法，通过调功法对水温系统进行控制,实现在 0—100℃范围内任意设定温度值，静态误差小于±0.5℃。 关键词： AVR 单片机 水温自动控制 模糊 PID 算法 (AVR Microcontroller Based Temperature Control System Abstract: This system ATMEGA16 microcontroller as the core monitoring and control system using the temperature sensor AD590 0-100 ℃ temperature range to achieve real-time temperature acquisition, through triac BT136 control system for electric heating cup, using relay control system for semiconductor cooling heat tablet. Achieved through the keyboard line value for any temperature setting and adjustment of fuzzy PID parameters, real-time updates LCD1602 LCD displays the current temperature measurements and the keyboard set temperature. Fuzzy PID algorithm, the system transfer function method of temperature control, to achieve the 0-100 ℃ adjustable set temperature, the static error is less than ± 0.5 ℃. Keywords: AVR microcontroller water temperature control fuzzy PID algorithm )
