近来在发现玩Arduino比较热,网上淘了一块Mega 2560,玩了一段时间,近日又淘了一块HY-TFT320彩屏,控制IC是SSD1289,参照《arduino学习笔记33 - Mega 2560+TFT3.2寸屏的演示实验 》资料连线演示实验。连线见图1
连接方法是这样的:
(LEDK -> GND) only 3.2″ TFT LCD
LEDA -> 5V
VCC -> 5V
RD -> 3.3V
GND -> GND
DB0->DB7 to pin D37->D30
DB8->DB15 to pin D22->D29
RS -> D38
WR -> D39
CS(pin6) -> D40
RSET-> D41
但是TFT规格书说明:背光电源(LED_A 引脚):背光电源最高3.2V,难道连接:LEDA -> 5V 有问题吗?
1.系统XP+Arduino-1.5.6-r2,出现情况见图2
参考弘毅网上‘参考使老版本库文件支持Arduino 1.0 IDE的方法’一文(
http://www.geek-workshop.com/forum.php?mod=viewthread&tid=1030)
将“#include "WProgram.h"”字段和把两个文件的“#include "WProgram.h""字段替换为:
#if ARDUINO >= 100
#include "Arduino.h"
#else
#include "WProgram.h"
#endif
这样编译能同过,上传代码,但通电后没有啥显示的,一遍白光,情况见图3.
2.改用系统Xin7+Arduino1.05-r2,情况基本一样:能顺利通过编译,就是屏幕没反应,没有什么显示,白光。运行库内带的示例情况也一样,屏幕没反应。
询问店家,是不太懂的一类,无Arduino应用资料,只提供51的资料,
请教高手是Arduino还是HY-TFT320引线有问题?弄不出显示的。
