单片机+带中文字库的12864中文汉字显示错误,显示的汉字不是我写的

ID:997450 发表于 2022-1-14 11:50

已经解决了，是我的文件编码有问题，我的是utf-8 但是keil识别的是ANSI

ID:526543 发表于 2022-1-9 11:55

先声明再调用吧

ID:844772 发表于 2022-1-9 10:55

1、一般都用并行试试程序，没问题再用串行。2、我觉得你的程序是延时的问题，像是发送数据时都没有延时，本来发前应测LCD忙的，你都给省略了。

ID:1000847 发表于 2022-1-9 10:27

是不是类型设置不正确？

ID:997450 发表于 2022-1-9 09:30

我这个电路用并行不太容易，毕竟不是实验板，是我自己焊的

你套用这个程序试试。

这是并行的？

第117行，uchar 改成 uint 怎么样？

实践告诉我，改完后屏幕全乱了

ID:8222 发表于 2022-1-9 01:26

第38行，“一闪一闪”，先声明一字符串，再引用。

改并行吧

串行口真好！省IO口。
12864 这种低分辨率的黑白屏，数据量少，串行通信完全没有问题。
还有，像1602这种，我也用4线连接的。

ID:447439 发表于 2022-1-8 22:55

改并行吧

你套用这个程序试试。
