请问楼主操作其他的会有抖动吗?
1:有示波器测量参考电压是否波动如果稳定表明电压没有问题的
2:把刷屏率降低一点试试。
3:真的不行在看看屏的参数
降低刷新率其实就是降低VCLK,这个方法是了,把VCLK降到22M或16.7MHz,抖动问题是能解决,但屏的参数要求VCLK的范围是25-40MHz,低于25MHz仔细看屏会有一点点闪……
看来楼主对显示要求比较高啊!

检查时序和电路,SCL和SDA要加上拉

谢谢楼上的朋友,你看的哪版规范呀?我看得1.3a版本的,共156页,第21页是type A接口的特性图阿,不知道你说的在哪儿?告诉我章节好吗?

要包含I2C,不要写SET BSP_NOI2C=0,写SET BSP_NOI2C=,或者干脆不写。
可是为什么呢?

在这个推荐的帖子里面有很多这些论述,看看去吧。
嘿嘿,划重点,想起了大学。呵呵。

用智能设备的——Win32智能设备项目,然后选择DLL.我也是这么弄的,不过添加到系统后,驱动就会编译出错,这个问题一直让我和郁闷.

改了语言后,不仅仅是编译BSP哦,
你最好重新Sysgen一下。
重新Sysgen后也还是一样的,不行呀!

看看你的IO配置成什么状态了?
感觉像是ADC的配置不完全

想参加今年的研讨会 半天没见消息

主要是书啊 只了解一些三极管 二极管什么的基础知识 真正要看懂电路图设计电路图就不行了 学校一两周才有一个电路图

版主的比喻真到位

我重新编了个程序,启动后同样弹出对话框,“50 not found”,不知道什么意思。
Settings 有三个选项;1、not useing MFC, 2、use MFC in static library 3、use MFC in shared dll
如果选3,弹出的对话狂是乱码,用1和2,弹出“50 not found”,因为该对话框右上角只有ok(x是灰的),点ok后,没反映,对话框也不关闭,就死机。
选2 然后在setting--C/C++----prepro..defin.里面加个_AFXDLL 试试

没搞过关注.

晕看错了。。。。。你在生成public里面的lib???上面说错了。。。。这个没接触过。。

谢谢各位赐教,不过我还是不太懂“位域”,还请高手说明白点!
联合体我倒可以试试!

我想弄清楚到底怎么坏了,给个原因啊,死也要弄个明白啊。。。
