4实验结果
通过Mplab软件编程之后，编译通过，之后使用ICD2下载程序到单片机上，经验证，通过接通电源后，成功控制Nokia5110LCD显示器显示自己的名字LiuJianZhong。
5心得体会
通过这次试验，我收获良多，单片机试验要求的是一种思维的创新，而不是简单的重复老师所说的试验步骤。
单片机随着城市的发展，已经得到了进一步的应用，在今后将会有更大的发展。
在这次试验当中，一开始我不断的调试，都无法显示出想要的效果，我开始以为是程序的问题，所以在程序上花了比较大的功夫，不过发现不管我怎样修改程序，都无法显示或者显示乱码。
于是，我请教了老师，老师告诉我这是电路连接的问题，后来经过我的仔细检查，发现真的是电路连接错误了。
于是在改进之后，达到了我预期的效果。
当然，在试验中我还遇到了许多问题，不过不管做什么事，计划是很重要的，做事没有顺序，做事情就会比较乱，很难成功。
而且做事要多动脑，选出最好的方法。
最后还要注重细节，细节决定成败，这句话在这次课题中不仅一次得到了验证。
今后在实验课上，我会更认真去动手操作，把理论与实际相结合！
