接上文| # 【开鸿智谷NiobeU4开发板免费试用体验】Demo例程； |
感谢开鸿智谷研发人员依然小烨哥和 大佬们的支持指导。
想用开鸿智谷NiobeU4开发板资源 （GPIO02、GPIO27）输出，（ADC1_CH0上有SW4和SW5两个按键）模拟输入，板（GPIO02控制双色LED的红色、GPIO27控制双色LED的蓝色）LED，板（ADC1_CH0上有SW4和SW5两个按键）button，来通过光耦中间继电器控制加热设备。
程序根据厂家提供资料 ，想采用鸿蒙LiteOS系统。
开发自己的应用程序，
方法1：
- 需要在menuconfig中关闭 use openvalley niobeu4 application选项，然后在niobeu4_src/vendor/openvalley/niobeu4/demo/BUILD.gn文件中modules选项中填入自己的应用程序目录名，目录下内容可参考其它示例程序。
方法2：
- 拷贝一份demo 案例目录重新命名新案例目录名，
- 修改niobeu4_src/vendor/openvalley/niobeu4/demo/Kconfig.liteos_m.applications
- 修改新案例目录名下.application_config
- 修改新案例目录名下BUILD.gn
- 修改新案例目录名下程序
准备采用 方法2。
控温程序（1）
起动系统及MobaXterm，
1. 新案例目录
拷贝一份niobeu4_src/vendor/openvalley/niobeu4/demo/002_system_los_thread
重新命名 niobeu4_src/vendor/openvalley/niobeu4/demo/301_user
2. 修改Kconfig.liteos_m.applications
在MobaXterm右侧
在niobeu4_src/vendor/openvalley/niobeu4/demo/目录
下打开Kconfig.liteos_m.applications文件，在最后的位置添加default "301_user" if NIOBEU4_APPLICATION_301:

构建源码
- 进入源码根目录，执行hb set命令并选择openvalley下的iotlink。
hb set
- 执行hb build –f脚本构建产生固件。
hb build –f
- 如图所示，编译成功，并查看生产的固件。
构建成功会提示类似如下信息。
[OHOS INFO] iotlink build success
[OHOS INFO] cost time: 0:03:28
- 查看生成的固件。
ls /home/lst/niobeu4_src/out/niobeu4/iotlink/bin/
| 固件名称 | 用途 |
| ---------------- | ------------------------------- |
| OHOS_Image.bin | OpenHarmony内核及应用镜像文件 |
| bootloader.bin | 启动引导镜像文件 |
| partitions.bin | 分区表镜像文件 |
烧录镜像
- 通过MobaXterm软件ssh登录服务器，将生成的文件Download到Windows系统下，如图所示。
Windows下可以使用Flash_Download_Tool工具进行烧录，点击这里开始下载。
- 在windows下解压flash_download_tool_3.9.2.rar。
- 双击解压后得到的烧录工具flash_download_tool_3.9.2.exe，chipType选择 ESP32, workMode选择 develop，进入主界面。
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。
图5 设备管理器图
- 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
-
点击 START 开始下载。下载过程中，下载工具会读取 flash 的信息和芯片的 MAC 地址。我们可以通过勾选框选择是否烧录该文件，一般我们在首次烧录时会全部烧录，为了加快开发效率，调试时只需烧录
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
运行镜像
烧录完成后需要按下复位键复位设备，程序才会启动。
推荐使用xshell进行串口调试，点击这里进行下载。
达到预期状态。
