[分享] Google Protobuf 库

MicroPython 1.17+ 的 Google Protobuf 实现

主要特点：

• KISS 和 ideomatic 代码库
• 嵌入式代码（包括自动生成的）应尽可能小且快
• 纯python代码
• 应该在尽可能多的设备上工作

支持的功能

• Protobuf 2 syntax
• Scalar types encoding and decoding with implicit and explicit defaults
• Nested messages
• Message type fields
• Enums without implicit default value
• Repeated fields (partly implemented)

TODO

• Protobuf 3 syntax
• Repeated fields complete and test (including packed)
• Test message fields
• OneOf fields
• Maps

Groups won't be implemented since they are considered depricated. Required fields check is not implemented for now in favour of efficiency.

已测试的硬件

• PC (Mac)
• ESP32-wroom
• ESP8266 (LoLin V3)

import animal_upb2
animal = animal_upb2.Animal()

animal.name = "Dog"

encoded_message = animal.encode()
animal1 = Animal.decode(encoded_message)

这个好像是第三方序列化接口啥的吧，pbuf 到处能看到应用
