A MAX7219 and ESP8266 based cryptocurrency display
These instructions will get you a copy of the project up and running on your local machine for development and testing purposes. See deployment for notes on how to deploy the project on a live system.
!! CAREFUL !! At the time of writing (22/05/18), the Arduino Board Manager has the v2.4.1 of ESP8266. This version is known to have a memory leak problem and I was struggling alot with this version ! The solution is to manually add the board with the lastest Git version. Follow the link to do it : https://github.com/esp8266/Arduino/blob/master/README.md#using-git-version
If the Arduino Board Manager version is > 2.4.1 or that you don't mind the memory link, follow these steps :
First thing is to add board support to your board manager. Inside the Arduino IDE, click on "Preferences". Under "Additional Boards Manager URLs, add :
http://arduino.esp8266.com/stable/package_esp8266com_index.json
Next, by going to "Boards Manager" you should be able to add "esp8266" by ESP8266 Community.
After that, you want to install three libraries :
ArduinoJson 5.13.2 by Benoit Blanchon
MD_MAX72XX v2.10.0 by majicDesigns
MD_Parola v2.7.4 by majicDesigns
There's only one thing that you need to do in order for the libraries to work.
Inside Arduino > libraries > MD_MAX72XX > src > MD_MAX72xx.h, you need to choose the right hardware your display is using.
Put a 1 to the corresponding line.
Example : For FC-16 based display :
#define USE_FC16_HW 1
