  • Hello All

    I am sorry to post something unrelated to the product post but I need some help. I am trying to write data to alot of 24bit RGB LEDs. currently I am writeing the data from a program on my labtop to an FTDI chip (via usb) and then an ATMEGA328. the ATEMGA328 then coveys the information to the LEDS useing a bit banging method for data and clock.

    So far I have managed to write data every 30ms to 400RGB LEDs at a baud of 500000bps. but a new project that i am involved with I might have to write data for 800 to 1600LEDs, and it looks like I need to go faster.

    What is a faster way to write data to these LEDs. would I have better luck with an ARM instead? please email me with any suggestions, comments starting points thanks

  • Finally the last parts for the huge LED show im building... I mean woof woof...

  • Check out this project my freinds and I did with 2 of these LED strips. We wrapped them around a speaker and programmed them react to music.


  • Check out this project my freinds and I did with 100 of these LEDs. We used them to make a LED screen that reacts to music.


  • ok something is confusing me. the data sheet for it says "Baud rates: 300 bps to 1 Mbits" and the data sheet also says "Baud Rates2 300, 600, 1200, 1800, 2400, 4000, 4800, 7200, 9600, 14400, 16000, 19200, 28800, 38400, 51200, 56000, 57600, 64000, 76800, 115200, 128000, 153600, 230400, 250000, 256000, 460800, 500000, 576000, 921600" in another.

    so here is my question. can this thing do 1Mbps or is the fastest it can go 921600bps.

  • RTFM or I will ravage and plunder!!!!

  • ahh to many captchas

  • baha this is punny

  • Just another slow Monday at SparkFun.

No public wish lists :(
