Description: 本次设计利用三菱FX2N系列PLC作为核心部件，完成一个八路抢答器控制系统的制作。该系统可供八个或八组分台选手同时抢答，总台掌握着启动/停止开关、抢答开始按钮、抢答复位按钮、主持人安静提示按钮和手动设置个分台计分按钮等，分台则具有一个抢答按钮。该系统由七段数码管显示倒计时、分台号、选手计分和当前时间、温度情况，并作为被控设备由PLC驱动。因为系统中有很多七段数码管，所以我运用了动态扫描的方法来减少端口数。有一个蜂鸣器提示抢答开始、抢答复位、回答超时、抢答违规、无人抢答和安静提示。有17个发光二极管，总台一个用来显示无人抢答和回答超时，每分台两个用来显示抢答成功和抢答违规。本次设计中，硬件电路设计使用AUTOCAD软件；使用GX Developer软件编写程序；利用GX Simulator仿真软件对八路抢答器进行各部分模块仿真，观察结果。-The design uses Mitsubishi FX2N Series PLC as a core component, eight-way Responder to complete a production control system. The system components for eight or eight players at the same time answer in Taiwan, with a total station holds the start/stop switch, answer the Start button, answer the reset button, the host quiet hint button and manually set the sub-sets of scoring buttons, etc., sub-station you have a answer in the button. The system consists of seven-segment display countdown, sub-station number, player points and the current time, temperature, and serve as driven by PLC controlled equipment. Because the system has a lot of seven-segment, so I used the dynamic scan method to reduce the number of ports. There is a buzzer to answer in the beginning, answer reset answer time out, answer in illegal, no one answer in a quiet and tips. 17 light-emitting diode, a total station is used to display and answer no answer in overtime, each sub-station to answer in two to show success and

Description: 一、 uboot是ppcboot和armboot合并而成，现在主流的bootloader为uboot和redboot
二、 bootm addr_kernel addr_initrd
三、 移植uboot时最好（一定）要找到一个自己板子的原形（即自己的板子是在这个板子上做一些修改而来的）的版本，这样就可以事半功倍。这样要修改的地方就比较少，也比较容易了。uboot支持很多平台，与一个具体平台相关的主要有三个地方：
1、./include/configs/xxxxx.h, 主要定义了flash、sdram的起始地址等信息，一般要修改flash的起始地址、大小，有时候会有位宽等。
2、./board/xxxxx/*， 这个目录下主要有两三个.c文件，主要为该平台的初始化和flash操作的函数。有时候flash的操作需要修改，不过一般都是找一个现有的支持该flash的驱动，一般情况在uboot别的./board/平台下就会有现成的，拷贝过了就可以了。
