测试例程
MicroPyhton 开发
BPI:bit 已经完整支持microPyton。固件、开发环境、代码与 wiki 文档已经整理到:
https://github.com/BPI-STEAM/BPI-BIT-MicroPython/wiki
功能提供
- 1. 提供 终端命令行操作工具
- 2. 提供 有线或无线操作板子
- 3. 提供 Pycharm IDE 开发
- 4. 提供 Microbit 函数库
我们现在在测试所有micro:bit 在线文档的例子,我们已经可以让BPI:bit 兼容micro:bit库,这样,microPyton对micro:bit的支持,可以直接在BPI:bit上运行。
下面就是BPI;bit运行:运行:https://microbit-micropython.readthedocs.io/en/latest/tutorials/hello.html 代码的 代码的效果。直接可以用。
