mini 8x8 led matrix - how to scroll?

Post by _alter_ego_ »

Hi guys!
I know, this might be a stupid question but i searched for hours and didnt find anything.
Can anyone tell me, how to scroll objects like in this video at 3:42 https://www.youtube.com/watch?feature=p ... p38A#t=220?
I loaded the 8x8 example sketch to the arduino uno and everything works, but i would like to scroll more than just letters. :wink:
I also found this site http://www.diyode.com/mini8x8/, but still i have no clue how to get things to scroll beside letters.
Any help is appreciated, thank you.

One of the examples for the NeoMatrix does text scrolling: https://github.com/adafruit/Adafruit_Ne ... letest.pde

You can use that as a reference for how our resident blink-stuff expert handles the job.

Re: mini 8x8 led matrix - how to scroll bitmaps NOT text

Post by _alter_ego_ »

Thanks for your help!

I will try to figure it out, although i'm not exactly sure how the example can help me. :roll:
Does that mean i have to tread a bitmap like text?

If i do static const uint8_t PROGMEM
xy_bmp[] =
{ B00111100,
B01000010,
B10100101,
B10000001,
B10100101,
B10011001,
B01000010,
B00111100 },
...matrix.drawBitmap(0, 0, xy_bmp, 8, 8, LED_ON);
matrix.writeDisplay();
the bitmap won't scroll.

So maybe someone can point me to the right direction from here?

HI,

I'm stuck with the same problem. I cant scroll a bmp. Wanted to scroll a bmp or a custom animation alongwith the text, but cannot get it to work.

Please help!
