Adapt smartmatrix to Espruino

[B1tb0t]

Hi, I realy love the smartmatrix library for my Esp32. My latest project is based on Espruino, but I want to use smartmatrix with it (there is no libaray for Hub75 led matrix yet). Is it possible to adapt this library to Espruino?

I’m not sure how that would work, and it’s not a trivial project. Is there an APA102 LED library for Esprino?

[B1tb0t]

I found no full libarary for APA102. There is some code to controll APA102 led strips with SPI. I am currently trying to include smartmatrix in the espruino firmware (https://www.espruino.com/Extending+Espruino+1). But it needs the arduino.h file to work, but I found no way to include it yet.

Maybe instead of including Arduino.h, remove the #include and see what definitions are missing and add them directly instead. It might just be a few definitions I use from Arduino, I’m not sure

Ok I removed the Arduino.h including and build again. Now there are a lot of small errors:

s it a version problem ?

Arduino.h probably includes a other required header files, like inttypes.h (not sure if that's the actual name). I can't tell you exactly how to fix this problem, but I'd start by finding Arduino.h in an Arduino install and adding it to your project, or including what's necessary from it.

I dont know mutch about led matrixes, but is it possible to write a matrix driver for the espruino graphics library (https://www.espruino.com/Graphics) ?

It might be possible, but not without a lot of work, which I'm not going to be doing myself. I'm going to close this issue.
