ICCAVR 转WINAVR flash存储问题
上面的程序在ICCAVR中可以实现液晶的正常显示,想请教用WINAVR的大师们,如何改在能在WINAVR中正常使用.如果把字库存储到flash中,然后读取出来,谢谢.
display.H 无字库液晶,字模数据表

}
有个关键字PROGMEM，读取的时候用 pgm_read_byte（）；

以前折腾过一阵，翻了一堆程序翻出来的，你试下呢，我从ICC移植过去的，应该是试过的，时间久了......

谢谢你,非常感谢.. 忘说了，要引入这个头文件的 #include <pgmspace.h>...... ada1983 发表于 2012-9-4 16:46 static/image/common/back.gif
忘说了，要引入这个头文件的 #include ......
if (c1 ==pgm_read_byte(GB_16.Index) && c2 == pgm_read_byte(GB_16.Index+1))
最主要是你这种读取方式启发了我,如何取得结构体的数组成员地址...我仔细看了#include "Pgmspace.h"这个头文件定义,是不是现在都不用typedef char PROGMEM prog_char这定义里面的prog_char,我在studio 6里面如果这样定义: prog_char flash_a=100; 则会提示prog_char 未定义.现在是不是统一用PROGMEM,比如 unsigned char a PROGMEM =100;这样定义的话,就不会报错..还请明示,刚从ICCAVR转过来,对这个非常不解. const unsigned char sttBox PROGMEM ={
0x11,0x11,0x11,0x11,0x11,0x11,0x11, 0x11,0x11,0x11,0x11,0x11,0x11,0x10}
如上，都是直接在定义最后加PROGMEM即可......
prog_char 没研究过，当时移植了好用就没深究了，主要还是用ICC的:)
