STM32F429+STemWin，Hellow Word顯示兩個,字體顏色也不對，幫忙看看。
部分代碼如下,參考官方例程STM32Cube\Repository\STM32Cube_FW_F4_V1.23.0\Middlewares\ST\STemWin和原子哥的代碼
void main
{
......
GUI_SetBkColor(GUI_BLUE);
GUI_Clear();
GUI_SetFont(&GUI_Font24_ASCII);
GUI_SetColor(GUI_YELLOW);
GUI_DispString("hellow word\r\n");
GUI_DispString("Hellow\r\n");
....
}

uj5u.com熱心網友回復：
參考官方的例程STM32Cube\Repository\STM32Cube_FW_F4_V1.23.0\Projects\STM324x9I_EVAL\Applications\STemWin\STemWin_SampleDemo\STemWinuj5u.com熱心網友回復：
對比官方例程STM32Cube\Repository\STM32Cube_FW_F4_V1.23.0\Projects\STM324x9I_EVAL\Demonstrations\STemWin\MB1063\Gui\Target添加如圖所示代碼解決。
平時多積累，以后還可以作參考
