Altairis ESP8266-FC16 Library

Library for using the FC-16 display module (based on MAX72xx) with ESP8266 (NodeMCU) and Arduino IDE.

There is a very nice display module with MAX7219 and four 8x8 matrix displays. And then there is a very nice Arduino-compatible board called ESP8266 or NodeMCU. But there was no nice way to make them work together.

There was a way, using the LedControlSPIESP8266 Library by LABsub, but it was not very nice way, not high-level enough. So I created a new library on top of it.

Disclaimer: I'm web developer by trade, used to luxuries of C# and ASP.NET. Coding in C++ for Arduino is still kind of new to me and this is actually the first Arduino library I ever released.

If you notice some oddities in my code, please let me know, or even better, send a pull request.

Features

• Supports any number of displays (1-8).
• Allows addressing of all displays in one go (for example, 4-matrix block is treated like one display with 8 rows and 64 colums).
• Support for showing bitmaps.
• Support for scrolling text. Not fancy Parola-like effects, but plain right-to-left scroll is good enough.

How to Install and Use

1. Download and intall LedControlSPIESP8266 library, which is prerequisite.
2. Download latest version from Releases as a ZIP file and then use standard ZIP library install process. Or clone this repository into your Libraries folder.

For documentation see examples folder and wiki.

Development Note

I'm using Visual Studio 2017 and the "Visual Micro Arduino IDE" plugin for Arduino projects. There is appropriate .sln in the project folder. You can edit the .ino, .h and .cpp files in Arduino IDE or any other editor of your choice, just ignore the project folder.
