LCD12864 - 显示所画的图形
材料准备
- Ameba x 1
- LCD12864 Module x 1
范例说明
https://github.com/ambiot/amb1_arduino/raw/master/Arduino_libraries/LCD12864.zip
http://playground.arduino.cc/Code/LCD12864
安装library的方式请参考Arduino官方网站的教学文章将zip档的library加入Ameba：
https://www.arduino.cc/en/Guide/Libraries#toc4
接着打开范例 “File” -> “Examples” -> “AmebaLCD12864” -> “drawsketch”
并接线如下图:
程式码说明
Render() 在呼叫Initialise()之后执行,开始产生图形描绘程序
LCDA.Render()
DrawCircle(int x0, int y0, int radius) method功能为画圆形,参数x0为开始圆形的x座标位置,参数y0为为开始圆形的y座标位置,参数radius为圆形的半径
LCDA.DrawCircle(30,135,5);
RenderScreenBuffer(int screen) method功能为指定绘制的screen (分为上半部和下半部,1 = 萤幕上半部, 2 = 萤幕下半部)
LCDA.RenderScreenBuffer(2);
Draw(bool t, int x, int y) method功能为切换graphics mode
(参数t为true = graphics mode, x和y参数可以为任一数字)
(参数t为false = ASCII mode, x 为字元放置的位置0~23, ranging from 0 to 23, y参数则不会产生任何作用)
LCDA.Draw(false,4,0);
setPins(int tRS, int tRW, int tD7, int tD6, int tD5, int tD4, int tD3, int tD2, int tD1, int tD0) method为直接通过参数指定来绘制LCD萤幕
tRS: Register Set
tRW: Read/Write
tD7: Data line 7
tD6: Data line 6
tD5: Data line 5
tD4: Data line 4
tD3: Data line 3
tD2: Data line 2
tD1: Data line 1
tD0: Data line 0
LCDA.setPins(1,0,0,0,1,1,0,0,0,0); //0 LCDA.setPins(1,0,0,0,1,1,0,0,0,1); //1 LCDA.setPins(1,0,0,0,1,1,0,0,1,0); //2
