hi


i tried a code of 16*32 dot matrix on 16* 128 dot matrix display.

Code: [Select]

#include "myMATRIX.h"

#define RowA_Pin 2
#define RowB_Pin 3
#define RowC_Pin 4
#define RowD_Pin 5
#define OE_Pin 6 
#define Red_Pin 7 
#define Green_Pin 8 
#define CLK_Pin 9 
#define STB_Pin 10

void setup ()
{
     myMatrix.Init(Red_Pin,Green_Pin,CLK_Pin,RowA_Pin,RowB_Pin,RowC_Pin,RowD_Pin,OE_Pin,STB_Pin);
}   

void loop()
{
 myMatrix.clearScreen();
 myMatrix.printString(5,8,yellow,black,"Demo");
}



it gives me output on the display but it is repeating the displayed text after some pixel again.

is there any other pin configuration and library for 16*128 dot matrix display?


thank you

Use md Parola and md_max  library. Over there you can decide how many modules are in your display like :

#define MAX_DEVICES 12

You can find this libraries here:




And later you can find some examples , in your case that will be zones , because you want to display something in certain space of display:




Good luck !

Is your matrix controlled by the MAX7219 IC? You provide no details of the type of matrix you are using.

With the 7219IC this means that there are more matrices than the software thinks there are. When you update the display, the serial data communications pushed the 'current' data off the end of the 'known' modules into the others, which will show the old display as was previously on the 'known' modules before they were updated.

You need to find somewhere in the library that has the number of modules and change that to be those for your matrix.

If they are not controlled by the MAX7219, then this explanation may not be correct for your matrix.

in this library there is nothing mentioned about the connection for r1,g1 and r2,g2
