I'm developing a library that can output vga graphics using the ZX Spectrum color attribute model for arduinos.

The structure of that project is not very friendly to users of the Arduino IDE. Would you consider a pull request that restructures it according to the Arduino Library Specification (https://github.com/arduino/Arduino/wiki/Arduino-IDE-1.5:-Library-specification)? That specification is 100% compatible with PlatformIO but PlatformIO also allows project structures that don't follow the specification.
Yes, i'll do it soon.
I have updated the github repository.
For now it works on the atmega328p mcu boards.
The example prueba runs.
The schematich for nano on breadboard is ok, the schematich for uno is not tested but i guess is ok.
There are a couple of links to example videos.
