准备用mini板完成以下功能：按下开发板上的按键，呼出LCD屏幕上的菜单，然后通过触摸屏幕上的相应区域来调出下一级菜单
但是我的程序只能完成“按下开发板上的按键，呼出LCD屏幕上的菜单”的步骤，调出菜单后触摸屏幕却没有反应
求教
以下为各种初始化:
int main(void)
{
u8 flag; //flag=开启菜单条件
NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2); //设置中断优先级分组2
delay_init(); //延时函数初始化
uart_init(9600); //串口初始化为9600
tp_dev.init(); //触摸屏初始化
LCD_Init(); //初始化液晶
LED_Init(); //LED初始化
KEY_Init(); //按键初始化
usmart_dev.init(72); //usmart初始化
mem_init(); //初始化内存池
exfuns_init(); //为fatfs相关变量申请内存
f_mount(fs[0],"0:",1); //挂载SD卡
f_mount(fs[1],"1:",1); //挂载FLASH.
while(font_init()) //检查字库
{
LCD_Clear(BLACK); //清屏
POINT_COLOR=RED; //设置字体为红色
LCD_ShowString(60,50,200,16,16,"mini STM32");
while(SD_Initialize()) //检测SD卡
{
LCD_ShowString(60,70,200,16,16,"SD Card Failed!");
delay_ms(200);
LCD_Fill(60,70,200+60,70+16,WHITE);
delay_ms(200);
}
LCD_ShowString(60,70,200,16,16,"SD Card OK");
LCD_ShowString(60,90,200,16,16,"Font Updating...");
key=update_font(20,110,16);//更新字库
while(key)//更新失败
{
LCD_ShowString(60,110,200,16,16,"Font Update Failed!");
delay_ms(200);

delay_ms(200);
}
LCD_ShowString(60,110,200,16,16,"Font Update Success!");
delay_ms(1500);
LCD_Clear(BLACK);//清屏
