关于第三章问题求助
我因为没有example3.1的源文件，所以就按照裸奔三部曲做，但是烧如arm后，有图片显示，但对我的点击豪无反应，能不能帮我分析下，或者把example3.1发到我的信箱576592039@qq.com 查UART，我也遇到过！ yxl 发表于 2011-12-6 11:42 static/image/common/back.gif我也是刚刚做完这个实验，在主函数里添加while（1）循环有错误，搞的我好郁闷，最后就在源出厂程序的touchp ...
怎么改的 能把代码贴出来么 我在这卡了很久了 求救啊 恩 我搞定了 我是在中断里面加的 没用WHILE循环 谢谢啊 /*****************************************

我用的是7寸屏，如果你用的是4.3的话就再改改！我的附件上传不聊，我就把我改的touchpanel.c函数粘上来，还有图片函数就你自己写了，太多了我就不传了 1013269594 发表于 2011-8-29 09:05 static/image/common/back.gif
查UART，我也遇到过！
求助我因为没有example3.1的源文件，所以就按照裸奔三部曲做，但是烧如arm后，有图片显示，但对我的点击豪无反应，能不能帮我分析下 我也是刚刚做完这个实验，在主函数里添加while（1）循环有错误，搞的我好郁闷，最后就在源出厂程序的touchpanel.c中改成功了 谢谢 ，我也成功了
