So flip the line of modules 1234 to be 4321 and change the mapping in the header file so it works correctly.

Released version 2.6 of the MD_MAX72xx library. Now supports the hardware louwin highlighted in earlier posts (designated FC-16).

Changes from previous version:
- Improvements to HW_Mapper utility
- Added USE_FC16_HW for FC-16 display modules
- Added USE_OTHER_HW for user defined hardware configuration
- Fixed incorrect spelling for HW_REV_COLS in transformbuffer() & corresponding bug
- Added PrintText_ML example

Any problems please let me know.
I just tried the new version of the library, and I confirm the bug I reported in #347 seems to be fixed. Thanks Marco!

Also, I don't have the problem of the text slowing down anymore, so maybe it was a power supply-related issue or something like that.

EDIT: This problem occurs when MAX_DEBUG is set to 1 in MD_MAX72xx_lib.h. I guess this is normal somehow.

MAX_DEBUG turns on lots of messages on the serial port so it would slow it down a lot.

Yes, I saw that. I had set it to 1 when debugging the initial bug. And the old library was still loaded in my environment, instead of the new one. Anyway, everything works fine now, thank you.

Marco, is the problem with Arduino IDE 1.6 solved or not yet?

What problem?

The problem you refer to in post #425.
I didn't try it, but I was wondering if I should wait a bit before upgrading or not.
Thanks

That was an error of a header file missing in the example. Not related to the IDE version.

Where is the Line.P.displayScroll function in library?
I can't find it
