NOKIA5110屏幕电压表

maojidan

如题，晚上吃过晚饭，想起来前几天买的5110的屏幕一直搁着蛮对不起它的，于是就动手查查驱动程序，在论坛里看见别人写的程序，于是稍加修改变成了一款数字电压表。程序有点乱，是一时兴起写的，现在拿出来给大伙参考参考。[pre lang="arduino" line="1" file="LCD5110"]//端口定义
int LCD_RST=3;
int LCD_CE=4;
int LCD_DC=5;
int SDIN=6;
int SCLK=7;

很好的应用，顶一个，我5110回来我也玩一下！

不错啊 ，程序好长。   
最高能测多少伏？用几号端口测电压？精度怎么样？

不错啊 ，程序好长。   
最高能测多少伏？用几号端口测电压？精度怎么样？

最高能测5v，用的是A0端口，精度的话一般般，只能到小数点后面2位。

楼主，我试了下你的程序，在我的5110上显示的一片黑，侧着能看到显示的内容，我应该改下哪个参数呢，偏置电压还是哪个呢？能解答一下吗?我查了下5110的资料，没看太明白。

把屏幕的供电电压设置为3.3V试试~

Sorry,我记错了，我今天又试了一下，如果接到3.3V上，LCD不工作。这是效果

请问怎么显一个变量，LCD_write_english_string(66,2,"V");如果这个V是一个100位的变量，怎么显示？求助
