接上文| # 【开鸿智谷NiobeU4开发板免费试用体验】控温（1）； |
感谢开鸿智谷研发人员依然小烨哥和 大佬们的支持指导。
准备在上文基础上增加LCD。本文参考大佬们成功移植，
LCD方法：
起动系统及MobaXterm，
cd niobeu4_src/vendor/openvalley/niobeu4/demo/301_user/
git clone https://github.com/lvgl/lvgl.git
参考指令：
cd ~/niobeu4_src/vendor/openvalley/niobeu4/demo/301_user
cp -rf ../107_hdf_spi/st7735.h
cp -rf ../107_hdf_spi/st7735s.c
cp -f lvgl/examples/porting/lv_port_disp_template.c lvgl/lv_port_disp.c
cp -f lvgl/examples/porting/lv_port_disp_template.h lvgl/lv_port_disp.h
复制lvgl/lv_conf_template.h为lvgl/lv_conf.h
将#if 0改为1
暂时将542行的#define LV_USE_WIN 1 改为0
暂时将 39行#define LV_MEM_SIZE (128U * 1024U) / [bytes] /改为
#define LV_MEM_SIZE (12U * 1024U) / [bytes] /
按需提供堆大小,过大可能编译不过,过小可能影响创建对象。

* 1. Create ONE buffer:
* LVGL will draw the display's content here and writes it to your display
*
* 2. Create TWO buffer:
* LVGL will draw the display's content to a buffer and writes it your display.
* You should use DMA to write the buffer's content to the display.
* It will enable LVGL to draw the next part of the screen to the other buffer while
* the data is being sent form the first buffer. It makes rendering and flushing parallel.
*
* 3. Double buffering
* Set 2 screens sized buffers and set disp_drv.full_refresh = 1.

| bootloader.bin | 启动引导镜像文件 |
| partitions.bin | 分区表镜像文件 |
Windows下可以使用Flash_Download_Tool工具进行烧录，点击这里开始下载。
图4 Flash_Download_Tool打开页面图
连接开发板的TypeC口到PC，查看设备管理器，确定串口端口号。
进入下载页面，填入需要烧录的 bin 文件和对应的烧录地址，并根据自己实际 需求填入 SPI SPEED、SPI MODE、COM 及 BAUD。
固件对应烧录地址如下。
//out/niobeu4/iotlink/bin/bootloader.bin ----------> 0x1000
//out/niobeu4/iotlink/bin/partitions.bin ----------> 0x8000
//out/niobeu4/iotlink/OHOS_Image.bin ----------> 0x10000
图6 烧录设置页面图
OHOS_Image.bin即可。下载完成后，可以看到如下提示。图7 烧录成功页面图
烧录完成后需要按下复位键复位设备，程序才会启动。
