Developing with the ESP-ADF

IDF Version

The following table shows the ESP-IDF versions supported by ESP-ADF at the current time. The label alt text means supported, and the label alt text means not supported.

The ESP-IDF master branch is marked as not supported because the major feature changes it has introduced may cause conflicts with ESP-ADF. Yet, the ADF examples not affected by those feature changes can still run correctly on the IDF master branch.

End of Life IDF branches are removed. See IDF Supported Periods for details.

The Open Source Evaluation Index is derived from the OSS Compass evaluation system, which evaluates projects around the following three dimensions

1. Open source ecosystem

  • Productivity: To evaluate the ability of open-source projects to output software artifacts and open-source value.
  • Innovation: Used to evaluate the degree of diversity of open source software and its ecosystem.
  • Robustness: Used to evaluate the ability of open-source projects to resist internal and external interference and self recover in the face of changing development environments.

2. Collaboration, People, Software

  • Collaboration: represents the degree and depth of collaboration in open source development behavior.
  • Observe the influence of core personnel in open source projects, and examine the evaluations of users and developers on open source projects from a third-party perspective.
  • Software: Evaluate the value of products exported from open-source projects and their ultimate destination. It is also a concrete manifestation of "open source software", one of the oldest mainstream directions in open source evaluation.

3. Evaluation model

    Based on the dimensions of "open source ecosystem" and "collaboration, people, and software", identify quantifiable indicators directly or indirectly related to this goal, quantitatively evaluate the health and ecology of open source projects, and ultimately form an open source evaluation index.
