When I try to compile, example of DMD master dmd_demo using arduino 1.8 IDE on the arduino uno chines model, comes following message.
"In file included from /home/namal/Arduino/libraries/DMD-master/examples/dmd_demo/dmd_demo.pde:43:0:
/home/namal/Arduino/libraries/DMD-master/DMD.h:52:2: warning: #warning CHANGE THESE TO SEMI-ADJUSTABLE PIN DEFS! [-Wcpp]
#warning CHANGE THESE TO SEMI-ADJUSTABLE PIN DEFS!"
Is that error?
and not working panel character properly.
Namal
Is that error?
It is a warning, not an error.
That is not to say that the logic and actions of your code are correct. Please post it here.
Ok.
#include <SPI.h> //SPI.h must be included as DMD is written by SPI (the IDE complains otherwise)
#include <DMD.h> //
#include <TimerOne.h> //
#include "SystemFont5x7.h"
#include "Arial_black_16.h"
//Fire up the DMD library as dmd
#define DISPLAYS_ACROSS 1
#define DISPLAYS_DOWN 1
DMD dmd(DISPLAYS_ACROSS, DISPLAYS_DOWN);

not working panel character properly.
What should the program do ?
What does it actually do ?
sir i want to add more p10 board.what are the changes from dmd example

I have no experience of the library but this
DMD dmd(DISPLAYS_ACROSS, DISPLAYS_DOWN);
creates one instance so you could probably create a second one named anotherDmd like this
DMD anotherDmd(DISPLAYS_ACROSS, DISPLAYS_DOWN);
Whether it will work I have no idea !
Whether it works or not, please give the objects better names than in my description.
if u have a sketch......for p10 16x64 or 16x96
pliz that setch
Any one please give me the link or direction to get internal circuit diagram of HUB75 (P6)
Thanks
Hi , I need to use arduino with multi rows P10 LED module can you help me which arduino can be useful for me ansd if I need more components ?
Could you please give us some more clues as to which
multi rows P10 LED module
you are using ?
