it is keil-c program for run lcd on lpc1768 ECA.com

说明：  工业以太网现场总线EtherCAT及驱动程序设计的论文，共大家学习和参考(The thesis of industrial Ethernet Fieldbus EtherCAT and driver design is for your reference)

说明：  单片机控制1602液晶反显程序，非常经典是51hei光盘里带的(SCM control program 1602 LCD anti-significant, very classic is a CD-ROM Li Dai' s 51hei)

2015年电赛频率计，优点：简单易实现，精密度高(2015 frequency race frequency meter, advantages: simple and easy to implement, high precision)

ADLINK PCI系列的编程文档，利用板卡实现数据采集、控制等要求时必不可少(ADLINK PCI series of programming documents, the use of cards for data acquisition, control and other essential requirements)

实现RC522射频芯片的读写，扣费，注册，和充值等功能，51单片机绝得可以用(RC522 RF chip to read and write, chargeback, registration, and recharge function, 51 MCU must have to be able to use)

名称：门禁模拟 模拟现实中门禁系统，可以输入密码进入也可以呼叫住户，再由住户按下开门按键 实现改密码功能，密码保存在24c02中能保证掉电不丢失密码。八个LED灯分别代表 8家住户，其中开门按键为共用，还带有忘记密码恢复按钮，模拟恢复出厂设置， 显示部分为LCD1602。程序共分为3种模式，分别为 等待输入 密码修改 呼叫住户 3种模式，其中等待输入是主要状态，所以在进入密码修改 呼叫住户模式后如果 长时间没有操作能自己切换到等待输入模式。(Name: Access Analog Simulating real access control system, you can also enter a password to enter the call households, again by pressing the open button households Implement change password function, the password stored in the 24c02 can guarantee non-volatile password. Eight LED lights represent 8 households, which opened the door keys are shared, but also with forgotten password recovery button, analog restore factory settings, Display part LCD1602. Program is divided into three modes, namely, waiting for a password to modify call households 3 modes, which is the main input wait state, so call households entering the password change mode if Their long time operation can be switched to the standby input mode.)

说明：  单片机MC9S08AW60脉宽调制 TPM1CH3 LS2亮度控制 KBI SEG控制亮度等级 。本工程为定时器输出PWM波测试工程实例通过对PWM占空比的调节,实现小灯的渐亮的功能,当占空比为100％时再从0％逐渐增加.PWM的周期一定要足够的快,否则其输出电压的波动范围很大,且测不出一个稳定的电压值,这样通过就观察不到小灯渐亮效果. 另外,在改变PWM的周期和占空比之前和之后要分别禁止和使用。(MC9S08AW60 pulse width modulation TPM1CH3 LS2 brightness control KBI SEG brightness level. This project is an example of testing the output PWM wave of the timer. By adjusting the duty ratio of the PWM, the function of the small lamp gradually brightening is realized. When the duty ratio is 100%, the period of the small lamp gradually increases from 0%. The period of the PWM must be fast enough. Otherwise, the fluctuation range of the output voltage is large and a stable voltage value can not be measured, so the effect of the gradual brightening of the small lamp can not be observed. In addition, the period of the PWM is changed. Before and after duty cycle should be prohibited and used separately.)

说明：  19264液晶时钟，带按键，两页显示，带闹铃，带农历属相，二十四节气显示，功能非常全(24 solar terms with lunar week alarm)
