这几个引脚设置对吗，有波形没有，你的硬件有没有问题，是用STM8？时钟是多少？

这里的延时asm("nop"); asm("nop"); asm("nop"); 是需要的，代码就这些，没有什么要注意的了，你用示波器看波形吧！

你好，不显示的问题找到了，是因为我的rd引脚初始化时没有设置高电平，设置低电平就可以了。但是显示不清楚，还请指教。

你是说显示的色度吗，可以调节LCD电压偏置电压，对比度那些，具体看你的LCD资料

我的显示屏的供电电压是3V，HT1622的偏压可调范围是0~3V,这个范围的电压都试过了，但是没有用，很模糊，正面看基本上看不清楚，SEG脚和COM脚的波形如附图，绿色的是COM脚，黄色的是SEG脚。请指教！谢谢！

shuxmpx123 发表于 2013-7-15 13:31:03

能显示说明通信没有问题了，看不清楚的话，就是配置的问题，仔细看看1622有哪些需要配置的都试试吧。

HT1622的com口输出1/4偏压，分别是：0、1/3V、2/3V、V，和我之前理解的不太一样，我想1/3偏压是：0、1/2V、V，不知道这样理解是否正确，请指教？
