Changing background color

<< < (2/3) > >>

linuxstb:
Your first attempt looks correct to me, but as others have said, looping through all 14 million colours will take a while...

Can you post the entire source to your plugin?  Maybe something else is causing it to fail.

jonashn:
It's just the helloworld plugin with the background-changer code added:

--- Code: ---#include "plugin.h"

PLUGIN_HEADER
static struct plugin_api* rb;


enum plugin_status plugin_start(struct plugin_api* api, void* parameter)
{
    (void)parameter;
    rb = api;

    rb->lcd_set_backdrop(NULL);
    rb->lcd_clear_display();
    unsigned int a,b,c=0;
    for(a=0;asleep(HZ/10);
            }
        }
   
    }

    return PLUGIN_OK;
}

--- End code ---

linuxstb:
You need a call to rb->lcd_update() in there (e.g. just before the rb->sleep() call).

jonashn:
Thanks linuxstb! That works.

Wait .. what?  The original code did have the lcd_update  ..   so how come the original post complained it didn't work?   ???
