先启用RASC创建一个图形化配置的工程，设置按钮P015为输入，并配置上拉电阻

再启用P103和P104为输出模式
然后在entry函数完成以下内容

void hal_entry(void)

{

        bsp_io_level_t button_stat;

        uint32_t DELAY=500;

        /* TODO: add your own code here */

        while(1)

{

        R_IOPORT_PinWrite (&g_ioport_ctrl, BSP_IO_PORT_01_PIN_03, BSP_IO_LEVEL_LOW);

                R_IOPORT_PinWrite (&g_ioport_ctrl, BSP_IO_PORT_01_PIN_04, BSP_IO_LEVEL_HIGH);

        R_BSP_SoftwareDelay (DELAY, BSP_DELAY_UNITS_MILLISECONDS);

        R_IOPORT_PinWrite (&g_ioport_ctrl, BSP_IO_PORT_01_PIN_03, BSP_IO_LEVEL_HIGH);

                R_IOPORT_PinWrite (&g_ioport_ctrl, BSP_IO_PORT_01_PIN_04, BSP_IO_LEVEL_LOW);

        R_BSP_SoftwareDelay (DELAY, BSP_DELAY_UNITS_MILLISECONDS);

        

        R_IOPORT_PinRead (&g_ioport_ctrl, BSP_IO_PORT_00_PIN_15, &button_stat);

        if(button_stat==BSP_IO_LEVEL_LOW)

        {

                while(button_stat==BSP_IO_LEVEL_LOW){R_IOPORT_PinRead (&g_ioport_ctrl, BSP_IO_PORT_00_PIN_15, &button_stat);}

                DELAY=DELAY/2;

                if(DELAY<=2) DELAY=500; 

        }

        

}



#if BSP_TZ_SECURE_BUILD

    /* Enter non-secure code */

    R_BSP_NonSecureEnter();

#endif
