首先，真心感谢eeworld && digikey！感谢提供一个很好的学习机会，同时感谢瑞萨做workshop的同学，细致的讲解，反正我看了不下十次。

作业内容：

【所有任务视频】

【任务实现详情】

首先环境搭建出了点小问题，全靠教学视频和大佬们的帮助：

1. 【Follow me第二季第3期】哪位真的按照视频指南完成了E2 STUDIO环境搭建？ - DigiKey得捷技术专区 - 电子工程世界-论坛

2. 【Follow me第二季第3期】这个estudio神了，环境设置问题 - DigiKey得捷技术专区 - 电子工程世界-论坛
环境搭建好了后的作业：

3.【Follow me第二季第3期】搭建环境&下载调试示例程序 - DigiKey得捷技术专区 - 电子工程世界-论坛

IDE环境是：setup_fsp_v5_6_0_e2s_v2024-1
FSP的案例是：ra-fsp-examples-master

运行demo效果如下：

4. 【Follow me第二季第3期】入门任务：Blink，按键 - DigiKey得捷技术专区 - 电子工程世界-论坛

物料清单：就是EK-RA6M5开发板；

主要思路：通过RASC配置好LED1 LED2和按键；

实现代码：

    R_IOPORT_PinRead(&g_ioport_ctrl, BSP_IO_PORT_00_PIN_05, &key_state);

    if(key_state==BSP_IO_LEVEL_LOW){
        //软件消抖
        R_BSP_SoftwareDelay(10, BSP_DELAY_UNITS_MILLISECONDS);
        //点亮LED3
        R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_00_PIN_08, BSP_IO_LEVEL_HIGH); //LED3亮
        //等待按键松开
        while(key_state==BSP_IO_LEVEL_LOW)
        {
            R_IOPORT_PinRead(&g_ioport_ctrl, BSP_IO_PORT_00_PIN_05, &key_state);
        }
        //熄灭LED3
        R_IOPORT_PinWrite(&g_ioport_ctrl, BSP_IO_PORT_00_PIN_08, BSP_IO_LEVEL_LOW); //LED3灭
    }

6. 【Follow me第二季第3期】基础任务：DAC配置生成波形及性能测试 - DigiKey得捷技术专区 - 电子工程世界-论坛

物料清单：就是EK-RA6M5开发板；

主要思路：通过RASC配置好DAC和 GPT；

实现代码：

void g_timer0_callback(timer_callback_args_t * p_args)

{
    uint16_t dacvalue=0;
    static double w=0.0;

    w+=M_PI/90;
    if(w>=2*M_PI)
    {
        w=0.0;
    }
    dacvalue=(sin(w) + 1) / 2 * 4096;
    R_DAC_Write(&g_dac0_ctrl, dacvalue);
}

效果图：

7. 【Follow me第二季第3期】进阶任务：示例程序中新增命令打印信息 - DigiKey得捷技术专区 - 电子工程世界-论坛

物料清单：就是EK-RA6M5开发板；

主要思路：找到s_menu_items[]数组，该数组主要用于路由菜单内容，按规定添加测试内容即可；

实现代码：

test_fn kis_follow_menu(void)
{
    int8_t c = -1;
    bsp_unique_id_t const * p_uid = R_BSP_UniqueIdGet ();

    sprintf (s_print_buffer, "%s%s", gp_clear_screen, gp_cursor_home);

    /* ignoring -Wpointer-sign is OK when treating signed char_t array as as unsigned */
    print_to_console((void*)s_print_buffer);

    sprintf (s_print_buffer, MODULE_NAME, g_selected_menu);

    /* ignoring -Wpointer-sign is OK when treating signed char_t array as as unsigned */
    print_to_console((void*)s_print_buffer);


    /* provide small delay so board_status should be up to date */
    vTaskDelay (s_ticks_to_wait);
    xEventGroupSetBits (g_update_console_event, STATUS_DISPLAY_MENU_KIS);

    while (CONNECTION_ABORT_CRTL != c)
    {
        c = input_from_console ();
        if ((MENU_EXIT_CRTL == c) || (CONNECTION_ABORT_CRTL == c))
        {
            break;
        }
    }

    xEventGroupClearBits (g_update_console_event, STATUS_DISPLAY_MENU_KIS);
    return (0);
}

8. 【Follow me第二季第3期】扩展任务：一个波形信号发生器 - DigiKey得捷技术专区 - 电子工程世界-论坛

物料清单：就是EK-RA6M5开发板；

主要思路：直接产生正弦波和三角波，保存在数组中，然后将信号类型存储在flash上，此处选择QSPI flash。

实现代码：

    size_t half_period = size / 2;  // Half period of the triangle wave

    for (size_t i = 0; i < size; i++)
    {
        if (i < half_period)
        {
            // Rising edge: 0 to 4096
            array[i] = (uint16_t) ((double) i / (half_period - 1) * 4096);
        }
        else
        {
            // Falling edge: 4096 to 0
            array[i] = (uint16_t) ((double) (size - i - 1) / (half_period - 1) * 4096);
        }
    }

效果图：

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

【心得体会】

1. RASC工具真心好用，外设配置个人感觉比cubeMX不相上下；E2 studio第一次用，总体上不错，弱弱的建议：能否加个固件“下载”按钮？

2. 第一次接触信号波形，跟着大部队跌跌撞撞的学习然后实现自己的功能，感觉很棒，要是有个示波器就好了；

3. 任务安排的比较合理，循序渐进，譬如现在让我去做blink的功能，我就会选择中断的方式实现LED灯亮灯灭，而不是最初的监视按键电平。

能否加个固件“下载”按钮？

这个是个好建议

每次烧写都只能debug
