I HAVE THIS PROBLIME WHIT THE ORDERE OF LETTRE IN THE MATRIX I DONT NOW WHY
Do you have a question?
Please don't SHOUT.
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.
Hard to give any help from a low resolution video of a screen.
i have ardouino uno and the libraries is MD_MAX72XX-master/MD_MAX72xx_Test
tnx for help
More detail needed.
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.
thank marco_c for your help can you give an example i dont spaek english verey good may be if give an example i will undersend
We can't give examples if we don't know what you have.
Look here MD_MAX72xx strange behavior [SOLVED] - LEDs and Multiplexing - Arduino Forum or here LED matrices and MD_MAX72xx library: need help please - LEDs and Multiplexing - Arduino Forum, these are in the same forum you put this post into.
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)
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
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:
- The DATA IN for the modules is on the right hand side of the display
- Confirm that you only have one version of the libraries installed.
- Recheck the MD_MAX72xx.h to make sure that the FC-16 HW is the only one selected.
