个占用内存极少的菜单系统的实现"移植到AVR(W

痛苦的滋味 · 发表于 2016-5-9 22:58:36

是基于本站网友liandao著名的:一个占用内存极少的菜单系统的实现,我想把它改在AVR(WinAVR20100110)上执行,经过一番折腾,结果还是不正确,实在没招了,请大家帮忙指点一下.不胜感激.

现在编译通过:
代码(用PN)及proteus仿真文件:点击此处下载 ourdev_536007.rar(文件大小:269K) (原文件名:lcd_menu.rar)

显示字符串正常:GUI_DispStringAtBar(PSTR("Desktop"),0,0,126,GUI_TA_HCENTER);

显示菜单中的内容就不对了:
GUI_DispStringAtBar((PGM_P)(pgm_read_word(&MenuFunc[language].Text)),0,Enter_PosY - 2,126,GUI_TA_HCENTER);
GUI_DispStringAtBar((PGM_P)(&Tip[language].Text),0,Enter_PosY,126,GUI_TA_HCENTER);

显示效果:

以下是其中的部分代码:

//Bar型菜单的数据结构
struct Menu
{
const char **Text;    //指向显示内容数组的指针
// unsigned char **Text;    //指向显示内容数组的指针
