Christmas lights using led pixels (totally off topic)

[rsocor01]

Very nice!!! Thank you for posting. These LED pixels are new to me, so now I've got to play with them .

Since all you need to do is to send 24 bits serially per bit, why do you need 200 bytes of RAM? You can hold the bytes information in EEPROM memory or in the program memory.

50 pixels * 4 bytes (long variable 1byte is not used)=200bytes of Ram. The reason I need the ram is because most of the patterns which scroll use memory move commands on the RAM. Of course, you could do similar stuff out of Rom as well, but, I had to get this finished quickly with what I had at hand. I bought the pixels here http://www.aliexpress.com/item/Free-...635065030.html

Thanks Robert, Ioannis. These lights excited me a lot before Christmas, so I decided to get them. Now, I found there are some suited to billboard displays too. They are in the 5050 SMD format, are addressable and come in flexible strips. I haven't been able to locate a source for these yet. Might be interesting work to do a small display using these strips.
