红牛板已经好几年了,很少玩,最近看到emWin比较火,于是也尝试一下,结果很失望,功力不够!
就一个鼠标拖尾问题搞了将近1个星期,也硬着头皮去啃了N遍英文版本的emWin.PDF及ssd1963.PDF文件,当然也少不了坛里高手的杰作,但问题依旧.
问度娘也没有了办法,关键最烦的还是要忍受无数次的MDK罢工.
但我移植其它液晶驱动没有这个现象.
问坛里也没几个理哟,这是之前我发的求助帖子:http://www.amobbs.com/forum.php?mod=viewthread&tid=5625212&pid=8633423&page=1&extra=#pid8633423
功夫不负有心人,昨晚终于搞定了.
本来想搞搞气氛犒劳一下自己,顶到100楼才公布答案的,也不知道坛友是否支持?

以下是方法:
用的模板是LCDConf_FlexColor_Template.c
下面是代码,在关键部分都作了说明:
