我正在使用 Nordic NRF52 为嵌入式开发设置 VSCode。我注意到在 nrf_sdk 中有几个板和几个软设备的示例。我已经看到可以引用先前在任务、启动和扩展属性中定义的环境变量，例如：c_cpp、stm32-for-vscode。但是在工作区文件中有一个部分定义为 my_vars 以使工作区文件看起来像这样呢？

我尝试了一个 set_env 任务，在我的情况下，因为我在 Windows 中，所以运行一个批处理脚本：
set BOARD_NAME=NRF52840_MDK_USB_DONGLE
set MCU_NAME=NRF52840
set SOFT_DEVICE=S140
set BOARD_VARIANT_PATH=/pca10059/mbr
这将大大简化 SDK 示例的使用，并且可能是 NRF52 VSCode 扩展的潜在工作，如https://marketplace.visualstudio.com/items?itemName=bmd.stm32-for-vscode所做的那样。
