GD32重映射实战：从部分映射到完全映射的配置解析本文深入解析GD32微控制器的重映射功能，以定时器1的PWM通道为例，详细阐述了从部分映射到完全映射的实战配置流程。文章重点介绍了AFIO模块的核心作用、配置寄存器操作以及关键的避坑指南，旨在帮助开发者灵活优化PCB布局并解决引脚资源冲突，从而高效利用芯片外设功能。阅读详情

按照牛人傅贵的MMI案例培训教程,做到第15章控件的时候,照上面的代码写的,为什么结果出不了,,程序反而崩溃了.请教高手!!主体代码如下MyAppSrc.c:

gdi_handle my_anim;
gdi_handle my_layer;

fixed_list_menu My_fixed_list_menu; //创建一个全局的结构体对象,这是创建列表菜单框架

fixed_icontext_menuitem My_fixed_icontext_menuitem_common; //菜单项公共属性

#define My_fixed_list_n_items (8) //菜单项系数
fixed_icontext_menuitem_type My_fixed_list_menuitems[My_fixed_list_n_items]; //icontext型的菜单项列表
void *My_fixed_menuitem_pointers[My_fixed_list_n_items]; //指向菜单项列表的索引列表

S32 My_fixed_list_highlight_item = 0; //菜单高亮项索引

void stop_my_anim(void)
{
gdi_anim_stop(my_anim);
}
void mmi_myapp_entry(void);

void mmi_myapp_exit(void) //手动退出历史
{
history currHistory;
S16 nHistory = 0;

currHistory.scrnID = MAIN_MENU_SCREENID;
currHistory.entryFuncPtr = mmi_myapp_entry;
mmi_ucs2cpy((S8*)currHistory.inputBuffer,(S8*)&nHistory);
AddHistory(currHistory);
//gdi_layer_free(my_layer);

gui_fixed_icontext_menuitem_stop_scroll();
}

void mmi_myapp_entry(void)
{
S32 i;
S32 x,y,w,h;
color text_color = {255,255,0,100};

EntryNewScreen(SCR_MYAPP_MAIN, mmi_myapp_exit, NULL, NULL);
gui_lock_double_buffer();
entry_full_screen();
clear_screen();

gui_set_text_color(text_color);
gui_set_text_border_color(UI_COLOR_GREEN);
gui_measure_string((UI_string_type)GetString(STR_MYAPP_HELLO),&w,&h);
x=(UI_device_width - w)/2;
y=MMI_title_y;
gui_move_text_cursor(x,y);
gui_print_bordered_text((UI_string_type)GetString(STR_MYAPP_HELLO));

//开始显示菜单
memset(&My_fixed_list_menu,0,sizeof(fixed_list_menu)); //第一步创建列表菜单框架
gui_create_fixed_list_menu(&My_fixed_list_menu,20,MMI_content_y+5,136,MMI_content_height-50);
MMI_current_menu_type = LIST_MENU;

memset(&My_fixed_icontext_menuitem_common,0,sizeof(fixed_icontext_menuitem)); //第二步创建菜单项,这里是设置菜单项的公共属性
gui_create_fixed_icontext_menuitem(&My_fixed_icontext_menuitem_common,136,18);
gui_fixed_icontext_menuitem_set_text_position(&My_fixed_icontext_menuitem_common,24,0);
My_fixed_icontext_menuitem_common.flags |= UI_MENUITEM_DISABLE_BACKGROUND;

memset(&My_fixed_list_menuitems,0,sizeof(fixed_icontext_menuitem_type)*My_fixed_list_n_items); //这里是设置菜单项的单项属性
for(i = 0;i<My_fixed_list_n_items;i++)
{
My_fixed_list_menuitems[i].item_text = (UI_string_type)GetString(STR_MYAPP_HELLO+i); //菜单项文本
My_fixed_list_menuitems[i].item_icon = (PU8)GetImage(IMG_GLOBAL_L1+i); //菜单项图标
My_fixed_list_menuitems[i].flags = (UI_MENUITEM_CENTER_TEXT_Y|UI_MENUITEM_CENTER_ICON_Y);
My_fixed_list_menuitems[i].item_icon_handle = GDI_ERROR_HANDLE;
My_fixed_menuitem_pointers[i] = (void*)&My_fixed_list_menuitems[i]; //只想菜单项中的每一项索引列表
}

//联合菜单框架和菜单项
My_fixed_list_menu.items = My_fixed_menuitem_pointers; //菜单项索引列表
My_fixed_list_menu.common_item_data = (void*)&My_fixed_icontext_menuitem_common; //菜单项公共属性
My_fixed_list_menu.n_items = My_fixed_list_n_items; //菜单项系数
gui_set_fixed_list_menu_item_functions(&My_fixed_list_menu, gui_show_fixed_icontext_menuitem,gui_measure_fixed_icontext_menuitem,gui_highlight_fixed_icontext_menuitem,gui_remove_highlight_fixed_icontext_menuitem,gui_hide_fixed_icontext_menuitem,NULL,gui_get_fixed_icontext_menuitem_flag);

//显示菜单
My_fixed_list_menu.highlighted_item = -1; //菜单高亮项索引，此为菜单框架内部属性值，在跳转之前一定要设置为-1
gui_fixed_list_menu_goto_item(&My_fixed_list_menu,STR_MYAPP_HELLO);
gui_show_fixed_list_menu(&My_fixed_list_menu);
//显示菜单结束

gui_unlock_double_buffer();
gui_BLT_double_buffer(0,0,UI_device_width-1,UI_device_height-1);
SetKeyHandler(GoBackHistory,KEY_RSK,KEY_EVENT_UP);
}

void mmi_myapp_hilite_hello(void) //也是设置键盘响应事件
{
SetLeftSoftkeyFunction(mmi_myapp_entry,KEY_EVENT_UP);
}

void mmi_myapp_init(void) //开机用来初始化的函数
{
SetHiliteHandler(MENU_ID_MYAPP_HELLO,mmi_myapp_hilite_hello);
}

在MODIS模拟器上可以编译不报错,可以进到Organizer工具箱里面,,本应该点击Hello,World应该出来下级菜单的，现在只要电击就崩溃了,,请教高手!!
