Has anyone taken a peek at the MD_MAX72XX library? I’m trying to control a series of 8x8 LED displays driven by MAX7219 chips, and this library (combined with the sister FX library called MD_Parola) appear to be offer some great options. Unfortunately, trying to use the MD_MAX72XX library and running “examples/Parola_Test.ino” results in gibberish on the screens. I wonder if it’s a simple matter of initializing SPI correctly or something else trivial? It hasn’t received a Particle port yet afaik.

False alarm. It’s working fine. I had my SS pin connected wrong. Move along, nothing to see here. The library is awesome though, if anyone else is tinkering with these displays.
@jerware I want to use this library with a Photon so thanks for posting this.
Can anyone link me to a step-by-step on how to import a new (i.e. not pre-existing community library) library into the Web IDE?
Thanks.
