Glad to hear; looking forward to see you succeed. Since a have a feeble - or love - for (all kinds of) displays, I could but go forward and order some for me of the sort you reference with the GC9A01/SPI display controller and another kind of using the ILI9391/8..18bit 'paralell' (8080 interface). When I started with displays, Espruino was on slower hardware and the serial communication did not help with speed (many enhancements though came along and made it much better and what it is today). At that time, @Gordon 'cheered' me on to go ahead and add a prallel interface... Espruino Original board had enough pins do do so... but my brain did not have the skills-legs to tackle that. May be now has come the time to do that. (Exploring 2.8" Color TFT Touch LCD by Pacman Game attempt - More what you see published there was going on afterwards, but it never came to full fruition. Speed was one thing. The other one was memory: the definition of the pac man 'board' - even when heavily optimized - landed me in OUT OF MEMORY dungeon... for good... May be I go back and pick it up again).
Some of my other display endeavors you can find in my conversations on this forum, and many posts in other forum members' posts.
Driving LED matrix with shift registers such as 74HC595 DIY LED matrix from 40+ yers ago (that's why it is only one char w/ font size of 3x5, more was just 'not' affordable either by the LEDs or the RAM; it was just to figure the principle...)
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
