How to modify Teensy core files?

9

Basically it’s high time Custom platform packages per build environment · Issue #1367 · platformio/platformio-core · GitHub get’s implemented so this becomes easier.

You have modified your framework core files. Thus in the PIO architecture, you’ve modified the framework-arduinoteensy package. These sources for these packages and the packages themselves are defined in the platform’s platform.json file.

Example

So the actual clean way would be to fork the platform-teensy repository, modiy the platform.json to point to a different package repository which you control, and in this manifest add a new version of the framework-arduinoteensy and the download link to where you have your modified files.

Example from manifest.json from bintray:

  "framework-arduinoteensy": [
    {
      "sha1": "baa3e3c8e7e411b8f5f7918d11fecce08a7c531b", 
      "system": "*", 
      "url": "https://dl.bintray.com/platformio/dl-packages/framework-arduinoteensy-1.135.0.tar.gz", 
      "version": "1.135.0"
    }, 
    {
      "sha1": "3cc0670966ce4fd855762f30ba05b2cc0541580b", 
      "system": "*", 
      "url": "https://dl.bintray.com/platformio/dl-packages/framework-arduinoteensy-1.136.0.tar.gz", 
      "version": "1.136.0"
    }, 
...

Finally you must instruct your project to use the new platform with the changes pacakges by saying

platform = <git link to your platform-teensy fork here>
