[Lcd4linux-devel] Patch for multiple displays

[Stefan B. <st...@tr...>]

Hi Michael and others,

someone wanted to connect 4 displays at once, but it didn't work.
See here:
http://www.linuxforen.de/forums/showthread.php?t=3D235915

The problem is in drv_HD_goto(int row, int col), file drv_HD44780.c, lin=
e  =

839.
Here is a patch:

-------------------------
     /* handle multiple controllers */
     for (pos =3D 0, controller =3D 0; controller < numControllers;  =

controller++)
     {
         pos +=3D CROWS[controller];
         if (row < pos)
         {
             currController =3D (1 << controller);
             break;
         }
     }

     for (pos =3D 0; pos < controller; pos++)
         row -=3D CROWS[pos];
-------------------------

Greetings, Stefan
