Not too difficult to get working. *by D***E on Reviewed in the United States on August 4, 2019* I soldered both modules together with very short, stiff jumpers (removed plastic and bent included 90 degree pins) to make 1 long display. It works very well once I figured out how to properly configure everything. I'm adding these to my list of "known good and useful" Arduino accessories for future purchases! The only thing that could make these better is if the seller would just send them for free! :)I used a NANO, so your setup may be a little different... I couldn't find the answers easily out there in Arduino land, so I'm including what I used to get it all working with both the example Ticker sketch and my clock program in case you too are having issues.#include #include #include and for both displays connected together I needed://constants will not change...const int pinCS = 10; // Using Arduino NANO! Attach CS to this pin(10), DIN to MOSI(11) and CLK to SCK(13)const int numberOfHorizontalDisplays = 8; // 2x 4 module panels attached togetherconst int numberOfVerticalDisplays = 1;...and in void setup() matrix.setPosition(0, 7, 0); // The first display is at <0, 0> matrix.setPosition(1, 6, 0); // The second display is at <1, 0> matrix.setPosition(2, 5, 0); // The third display is at <2, 0> matrix.setPosition(3, 4, 0); //... matrix.setPosition(4, 3, 0); //... matrix.setPosition(5, 2, 0); //... matrix.setPosition(6, 1, 0); //... matrix.setPosition(7, 0, 0);// And the last display is at <7, 0> // ... matrix.setRotation(0, 1); // The first display is horizontal matrix.setRotation(1, 1); //... matrix.setRotation(2, 1); //... matrix.setRotation(3, 1); //... matrix.setRotation(4, 1); //... matrix.setRotation(5, 1); //... matrix.setRotation(6, 1); //... matrix.setRotation(7, 1);// The same for the last displayRotation was necessary because the library still expects each 8x8 module to be individual modules with the pins on top and bottom, instead of on the sides like these are. This works only if the incoming data lines are on the right hand side when looking at the LEDsI hope this was helpful! If it was, consider giving it a thumbs up! And don't forget to like and sub... wait, this isn't a YouTube script! Sorry about that! Thanks for watching! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars MAX7219 = GREAT! Using MD_MAX72XX, display mirrored? Add this to your Sketch! *by D***N on Reviewed in the United States on January 12, 2019* This MAX7219 is RED, BRIGHT, Great display and easy to use!If you are using the latest MD_MAX7219 {GitHub MajicDesigns/MD_MAX72XX} you may notice, that, your display looks odd (see my image)! Try adding this to your Arduino Sketch:#define HARDWARE_TYPE MD_MAX72XX::ICSTATION_HWComment or delete any other of the above #defines, ie //#define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW// Arbitrary output pinsMD_Parola P = MD_Parola(HARDWARE_TYPE, DATA_PIN, CLK_PIN, CS_PIN, MAX_DEVICES);Marco Colli has made major changes to his code, so, many of the code examples, that, you find on the Internet will not work, correctly! You no longer need to edit the MD_MAX72xx.h file (can't anyway, totally revised). Many of the YouTube videos suggest, that, you edit this file, this no longer possible with the latest update, available at GitHub.I hope, that, this helps! ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Bright Red LED Matrix Displays *by K***B on Reviewed in the United States on May 1, 2020* Average price. Two 4 character displays included. Very bright. Used as replacement for an existing design with no issues. Manufacturing seems solid. No problem daisy chaining them.
