2010-2014: The First Generation
The project started in January 2010 with the Arduino and the chipKIT boards. Soon were added the Wiring and LeafLabs boards.
The first embedXcode logo took a quarter of the icons from each of the IDEs. When Energia was launched, the rocket of its IDE was added on top to get the second embedXcode logo.
It became quickly clear that there were two kinds of users. Some users wanted to focus on core features while other were looking for more advanced features like external debugging, self-documentation.
This led to the embedXcode+ edition, based on donations. The logo for the embedXcode+ edition just added a plus to the logo of the standard edition.
2015-2018: The Second Generation
With more platforms being added, the logo had to change to suggest this wider choice.
There were as many different IDEs as platforms, customised to the colours of the manufacturer. So changing the targets board meant switching IDEs, while it was just selecting the board on embedXcode.
The second generation of the logo was introduced in September 2015 (forth version) and was refined one year later (fifth version), with some inspiration from flat design.
It conveyed the sense of diversity with 18 squares, which colours were taken from the their IDEs; and of unity with strong eX and eX+ letters.
