I was so impressed with Marco's Parola for Arduino project that I have, with Crossroads invaluable help, designed a PCB that uses the larger 60 mm square LED matrices. Here is the thread where this is developed and once I have done some minor tidying up of the Eagle package Marco has kindly allowed me to put the files up on his Parola site for download. The final version of the Eagle files in reply # 28 of that thread are functional aside from the fact that the drill hole size for the sixteen LED matrix holes are marginally too small. This, along with some other minor cleaning up will be done before they are put up on the Parola site.
Pedro.
EDIT - Marco has moved his Parola project to GitHub and consequently the Bigger Parola files have moved there too
Too true Crossroads,
I have been meaning to fire that guy for ages 8) And that was after a bit of Youtube video stabilisation too. I will have to shout myself a tripod for Christmas, which reminds me, all the best to you and your family for the festive season and stay safe,
Pedro
Thank you Pedro, and all the best to you and yours!

Hello

Download the latest MD_Max72xx library and read the documentation. There is now a library switch that allows the use of these more common displays. You need to change it before compiling the code.
you can define your own character if you want. The current character set does not have your characters.
You need to modify the data file where the font is located (it will have FONT in the name) and replace one of the existing characters with your own. The documentation tells you a bit about the character set definition and if you map out the current data as bits (convert from hex) you should be able to work it out.
