NOTE: You no longer need to make the modification in the Parola/MAX72xx Library. In the updated EXAMPLES there is now a line that reads: #define HARDWARE_TYPE MD_MAX72XX::PAROLA_HW And you can change the "PAROLA_HW" to the type of LED Matrix module you are using. For example I use the FC-16 boards so I changed the define to: #define HARDWARE_TYPE MD_MAX72XX::FC16_HW You can find the enum moduleType_t definition in the MD_MAX72xx.h file at around line # 265 to define which module you are using.

I use a lot of dumerals too. Very handy reference video about these modules. Thanks for the help and video!

You ROCK..... Really great bro. I was in search of this configuration and it wastes my whole day but I was unable to point out the bug. Before setting, my 32x8 LED matrix gives inverted alphabets. But now, ALL IS WELL. Thanks alot

I hope this video will help me get the matrix display working. I´ve got one laying around somewhere, but I´ve never had great succes with the dam´n thing... Thanks again Paul! Peace! ;)

this is a very needed video and will help many! something soo small and over looked causing soo many problems..

@magaphoto 6 лет назад

Thank you for your no-nonsense presentations. Hint: Find a chunk of dark-to very dark brown or red plexi. Hold it over the display with the LEDs at full (blinding) brightness. Now the reflected light from your lamps gets absorbed and the LEDs shine through. Hope it works. Best of luck. Thanks again.

Had an issue to display any kind of chars, the only output was lightening rectangles (1 or 2 of the 4 Matrix-Segments). Your advise to figure out via the documentation on github which model the board are fixes the issue. Now it works. Thank you very much.

I would recommend using OBS to record your screen rather than Bandicam. Free, no watermark, and very powerful. Just set it to Display Capture or Window Capture, then record.

@learnelectronics 6 лет назад

I have had no luck with OBS. Just crashes my laptop.

@kali_muon 6 лет назад

learnelectronics I would be happy to help you troubleshoot OBS if you're interested.

Which is the text editor you are using sir .subscribed

@javlontursunov6527 2 года назад

can u tell what is the versions of ur libraries ?

@sohailnadaf3509 5 лет назад

how can you display static text(no scrolling)? is there a code available for this purpose?

@bulk6622 3 года назад

Hi great video, These matrix alway fascinate me. Could you do the video please with 4 or 5 buttons that will dispaly a seperate message for eash button pressed. ie button 1 "Garden gate open" button 2 "It raining" button 3 "Shed door open", that could be dimmerable. My main plan would be to get 4 *cheap 433mhz transmiters and one reciver, and have matrex on the tv unit. That would be really cool, Many Thanks kevin

I’m using Pimoroni.com LED pHATs. I wonder if this library will work with them?

@nelsonproenca6177 4 года назад

Good, I am trying to make a Led panel with 8 modules of max7912, matrix 8 × 8, where it would be possible to pass a message after the click of a button. you would like to press the button and show an information in the panel, click again and another appears and so until you make 4 messages. How can I do this, because I can only scroll messages all together and not separately after the button click. Can anyone give me any tips, would be grateful.

great video do you have any experience with programing a arduino for a 5x8 led maxtrix using a max7219 have some board to try and get working could send you a few if would help thanks keep up the great videos

@learnelectronics 6 лет назад

No I don't

@raveruk72 6 лет назад

learnelectronics would you like some PCB boards to have a play with I can send you a few if you would like to have a look

@jdcalvillo 6 лет назад

what program do you use to open the header file?

@learnelectronics 6 лет назад

Any text editor will work

@8136821 6 лет назад

Thanks Paul for covering this. For those interested in more info about using the Parola library, I have a series of blog posts at my Arduino++ blog site (arduinoplusplus.wordpress.com/). Search for "Parola A to Z".

@richagainfrommichigan3601 6 лет назад

I keep getting the error message. Not used: C:\program files (x86) \ Arduino\libraries\MD_Parolola Exit status 1 Error compiling for board Arduino Nano. Do you have any idea why? All libraries are installed and I'm on the right com and board. I just can't seem to figure it out. Any help would be greatly appreciated.

@mikepanchaud1 6 лет назад

Rich again from Michigan Try MD_Parola. You have MP !!

@richagainfrommichigan3601 6 лет назад

Mike Panchaud I went back and checked and I just misspelled it in my comment. I am using MD_ Parola.

@squalazzo 6 лет назад

is it possible that there's not a better way to do that? I mean, if you update the library (i think both are in library manager, so if you just click UPGRADE you loose your customizations...), you're back at step 1... why not allow to put those defines at beginning of YOUR OWN sketch and override the library defaults? This way YOUR changes would survive the original author releasing new versions...

@learnelectronics 6 лет назад

Yes, you could make those changes.

@8136821 6 лет назад

That would be ideal but the problem is that the Arduino IDE does not respect the order of defines when it mangles the code before compiling. The user defines end up coming after the library. If you can find a way to make that work, let me know as it would be my preferred way as well.

marco_c thanks for the answer Marco :-)
