emwin的text

//频率显示
TEXT_Handle frequency = TEXT_CreateEx(x, y, xSize, ySize, hWinBase, WM_CF_SHOW, TEXT_CF_TOP|TEXT_CF_VCENTER, ID_TEXT_0, "");
TEXT_SetFont(frequency, GUI_FONT_D24X32);
if(strlen(frequency_buffer)==0){
　　TEXT_SetText(frequency, "28.5");
}else {
　　TEXT_SetText(WM_GetDialogItem(hWinBase, ID_TEXT_0), frequency_buffer);
}

当用

TEXT_SetText(frequency, frequency_buffer);

的时候出现文字重叠，考虑用

TEXT_SetText(WM_GetDialogItem(hWinBase, ID_TEXT_0), frequency_buffer);
文字就不会重叠
