I'm having a nightmare with these boards. I've got two boards linked together and using the code for the 128x16 matrix posted earlier in this thread. Issue I'm having is that setting inverse to either true or false has the reverse effect for each board. So if I set inverse to 'false' board one will be black text on red background while board two will have red text on black background.

SO my question is - is it possible to switch the boolean statement for inverse after the last column on the first board (columns 0 - 64 inverse true / columns 65 - 128 inverse false) so that both boards will display the same? If so can anyone give me any advice as to which part of the code I should look at. I'm happy to tinker with it, not expecting anyone to do it for me, just need some help getting started.

Many thanks!

Hello,
Im using this panel, 64x16 with promini+hc05 to change the character displayed.
How can i extend it to 128x16?
Thanks

Salve a tutti,

Cosa bisogna modificare al codice 128x16 per far funzionare tre display 64x16 collegate in serie.

Chiedo aiuto

kaziewip mi può dare qualche suggerimento?

Hi , I made it!

Thanks to this tutorial, it works perfectly: http://www.sunspot.co.uk/Projects/displays/LEDmatrix16x64/LEDmatrix16x64.html




I also made a custom case with acrylic.

Thank you for the help

I've been playing around with this display a bit and I agree that the code supplied has limited functionality.
However I've created an interrupt driven version of the code that constantly scans an 8x32 byte array to address each pixel on the board with ease.  Please use any part of this code you guys like.
Thanks, it's work using Arduino Uno, but can't work using Arduino Mega. Can help me?
