LAUNCHXL-CC3235SF: 如何添加串口打印驱动？

Part Number: LAUNCHXL-CC3235SF

您好：

我在syscfg中设置了串口打印，如下图，但是在main()函数里调用Display_print0(display, 0, 0, "Button:Long Pressed");接口时失败，打印不出信息，请问应该怎么解决呢？

对照例程display检查配置是否正确，是否有未包含的头文件等

display例程包含了串口和LCD，不只是LCD

 /*
     * Open both an available LCD display and an UART display.
     * Whether the open call is successful depends on what is present in the
     * Display_config[] array of the driver configuration file.
     */
    Display_Handle hLcd = Display_open(Display_Type_LCD, &params);
    Display_Handle hSerial = Display_open(Display_Type_UART, &params);

    if (hSerial == NULL && hLcd == NULL) {
        /* Failed to open a display */
        while (1) {}
    }

    /* Check if the selected Display type was found and successfully opened */
    if (hSerial) {
        Display_printf(hSerial, 0, 0, "Hello Serial!");
    }
