建议贴程序。还有液晶资料。是集成了字库的液晶屏么？

无字库的,程序稍等更新楼主位

security 发表于 2016-9-19 09:47:48

既然已经可以显示出来，但不稳定，
那么我想多半是总线时序过快的问题，
在总线操作适当加些延时（对照手册的时序要求），降低总线的速度，
试试看吧。

gliet_su 发表于 2016-9-19 15:36:32

送数太快了，慢一些。

bccuje_love 发表于 2016-9-19 15:58:56

定时，把
整个一下刷一下

runapp 发表于 2016-9-19 21:21:21

也可能是屏坏了？

4758866 发表于 2016-9-19 22:43:27

runapp 发表于 2016-9-19 21:21
也可能是屏坏了？

所有的都刷新就没有问题了

bbstr 发表于 2016-9-19 23:32:21

可能是iic时序被干扰了，写数据前先关闭中断，写完再恢复看看

4758866 发表于 2016-9-20 17:48:24

我现在是全屏刷新

ZHAOBAO511 发表于 2016-9-23 17:04:03

可以像中语言一样先用PROTEUS仿真一下，成了再写入单片机

你时钟别那么高

你时钟别那么高

即然都显示出来了，做计也没啥大题了，
不稳定就按楼上说的试试吧，一个是调整通信速度，要满足手册中的要求，最好按推荐值去做；
如果怀疑屏有问题，就换个个屏再试试看。

ayumi8 发表于 2016-9-24 13:11:17

这个是SPI串口的吧这种屏我也玩过也遇到过偶尔会显示错位错误的时候
