Is license MIT?

Hello,

Yesterday, the LICENSE file was added. It is the MIT license. Is it right?

Best regards,

Exactly! 🙂

Nice! 👍

I remember that FreeRTOS changed its license from `Modified GPL license` to the MIT license several years ago.

I think that this is the same impact.

Hello,

I've forked and cloned the repo and I'm looking files. I have a question. This repo has files which have the LGPL 2.1 license statements and non-corporate copyrights. For example:

https://github.com/arduino/ArduinoCore-renesas/blob/main/libraries/EEPROM/src/EEPROM.h

My understanding is that the files in the following folder are the MIT license. Is my understanding right?

Hello,

I'm looking files in the cores/arduino folder. I have a question. Is there any reason that MIT License statements shouldn't be added to each file?

I made a DOS batch file to add the statements to each file and push the updated files to my repo. For example:

Updated:

https://github.com/NoMaY-jp/ArduinoCore-renesas/blob/ArduinoCore-Renesas-explicit-MIT-License-Statements-in-files/cores/arduino/Arduino.h#L1-L25

Original:

https://github.com/arduino/ArduinoCore-renesas/blob/main/cores/arduino/Arduino.h

Best regards,
NoMaY

P.S.

The DOS batch file is the following:

set DST=C:\Renesas\GitHubDesktop\workspaces\work_ArduinoCoreRenesas\branch_1_Add_MIT_licence_to_files_in_cores_arduino\2_upd

I made a DOS batch file to add the statements to each file and push the updated files to my repo. For example:

Well, that's neat, but doesn't really help us. If there are missing license statements then please open a PR adding them.

I'll be closing this PR as the initial question has been answered.
