emwin之错误使用控件函数导致死机现象

@2018-10-15

导致死机的代码示例如下

 /**
  * @brief    widget ID define
  * @{
  */

 #define ID_WINDOW_0                  (GUI_ID_USER + 0x00)
 #define ID_TEXT_0                      (GUI_ID_USER + 0x01)
 #define ID_TEXT_1                      (GUI_ID_USER + 0x02)
 #define ID_EDIT_0                      (GUI_ID_USER + 0x03)
 #define ID_EDIT_1                      (GUI_ID_USER + 0x04)
 #define ID_TEXT_2                      (GUI_ID_USER + 0x05)
 #define ID_BUTTON_0                  (GUI_ID_USER + 0x06)

上段code中红色代码为控件函数误用，即TEXT控件的initialize部分使用了EDIT控件的函数，EDIT控件的initialize部分使用了TEXT控件的函数，这种情况编译器不会报警，但实际操作现象出现死机
