At a minimum you should be telling us what code you are using, if you are using a library and which one, what type of hardware you have, etc.

i have ardouino uno and the libraries is MD_MAX72XX-master/MD_MAX72xx_Test





tnx for help

Then you have probably not set the library to the right hardware type. Please read the documentation in the docs folder of the MD_MAX72xx library, especially the section about setting up the hardware. You need to tell the library what hardware you have so that it can compensate for the different ways that it is wired up.

We can't give examples if we don't know what you have.

Look here http://forum.arduino.cc/index.php?topic=514669.0 or here http://forum.arduino.cc/index.php?topic=515087.0, these are in the same forum you put this post into.

YOUNESTSFE

Hello ! thanks for help but there is no change in my problime whit matrix 32x8 +ardouino uno
Look i was gone to : Arduino/libraries/MD_MAX72XX-master/src/MD_MAX72xx
And i make 0 instead of 1(#define   USE_PAROLA_HW   1)

/**
 \def USE_PAROLA_HW
 Set to 1 (default) to use the Parola hardware modules. The
 software was originally designed to operate with this hardware type.
 */
#define   USE_PAROLA_HW   1

And  1 instead of 0 (#define   USE_FC16_HW   1)
#define   USE_FC16_HW   1
  The lettres oposet  like  b--- d
Pleas look at the video to see


marco_c

Seems like you made the right change but if there is no difference then check you only have one copy of the library installed.

How do you know that those are fc16? Post a link to where you got them from.

These modules are probably FC-16.

The video is pretty bad and hard to see what is going on.

Please make sure the following:
1. The DATA IN for the modules is on the right hand side of the display
2. Confirm that you only have one version of the libraries installed.
3. Recheck the MD_MAX72xx.h to make sure that the FC-16 HW is the only one selected.
