串口屏开发曲线和文字

 

 

 

 

 

 

http://wiki.tjc1688.com/commands/add.html#add-1

 

 

 //往s0曲线控件的0通道添加数据30  最大255
2 add s0.id,0,30

　　

 

add objid,ch,val

objid:曲线控件ID序号(此处必须是ID号，不支持使用控件名称)，推荐使用s0.id这种形式

ch:曲线控件通道号（范围：0-3）

val:数据 (最小0，最大255，还取决于曲线控件的实际高度，例如曲线控件实际高200像素
，当你添加的值超过200的部分就显示不出来。超过255软件会自动取低8位，即对255取余)

 

 

 

 

 、

串口软件

 add 1,0,30\xff\xff\xff

 文字设置

首先设置一个字库

 

 

 

 

 然后添加  文本

 

 

烧录进去
