  1. If you have one of those 5050/WS2811 aka WS2812 strips and you want to "wear" it, I have a board for you. Here are the specs: 20pin MSP430G2xx3 5V power supply 0.05" programming header UART input (allows pixel or sequence control) 11mm wide (0.45") 25mm long (1") 32mm long (1.25") - version with memory optional SOIC SRAM or EEPROM 1mm thick There are 4 boards on the panel, 2 with memory option. Assembled boards Board in the sleeve Board attached to 30 LED strip (0.5m)
  2. Those APA-102 leds that are packaged like ws281x pixels but you drive like a ws2801 (clk/data) have hit ebay.com. I ordered a 1 meter length and it arrived today. They look and feel like a ws2811 strip. It has 4 connections. 5V, GND, CLK, DATA. I whipped up a quick test and they seem to be happy: /** * APA-102 - test of 5 leds * * Author: rick@kimballsoftware.com * Date: 09-11-2014 * */ #include <fabooh.h> #include <main.h> #include <spi.h> namespace { typedef spi_attr_t<> SPI_MODE3_A; typedef spi_eusci_b0_t<CS, SCLK, MOSI, NO_PIN, SPI_MODE3_A >
  3. Hello I have get some ws2813 led, it is higher grade than the ws2812b with dual signal and the capacitance and resistance also package inside the led,it is much different, though apa102 also double but they are not the same, where can I get the code for the ws2813,I want to use the arduino to control it? thx for your help WS2813 LED.pdf
  4. Here is some code to drive ws281x strips using DMA driven SPI for the msp430f5529. I hadn't seen any example code showing how to use DMA and SPI. The example also provides some code that shows how to use inline asm that will work with both msp430-gcc and msp430-elf-gcc. The code below was tested with a ws2811 strip and msp430-elf-gcc. https://gist.github.com/RickKimball/9761b8f5a89d46a53939 -rick
  5. Hi, I'm trying to drive 15 ws2812b leds using a g2553 sitting on a Launchpad I'm finding the following behaviour a bit confusing and am wondering if anyone can provide an explanation... The code below is borrowed from RobG's post (http://forum.43oh.com/topic/2680-group-buy-10-o-rgb-smd-led-with-built-in-controller/page-4#entry23841 ) If I try to run at 16MHz the strip does not behave/work as expected BCSCTL1 = CALBC1_16MHZ; DCOCTL = CALDCO_16MHZ; However, if I set DCOCTL to CALDCO_1MHZ and keep BCSCTL1 at CALBC1_16MHZ (see code below) , the strip works fine... Is the clo
  6. WIZpix is an internet enabled RGB pixel controller with built in PoE. WIZpix uses W5500 internet appliance to connect to internet and MSP430F5172 MCU to control RGB pixels. Built-in DC/DC converter allows use of PoE, which eliminates need for directly connected power supply, ability to place controller far away from the outlet, and use of only one inexpensive CAT-5 cable. It
  7. WS2812 driver for Tiva is available here
  8. WS2812B is the new and improved version of the WS2812 LED (a.k.a. 5050/WS2811.) For chip details and differences between WS2812, see attached. I have LED and 30LED/m, 60LED/m strip samples (no, not free ) available on Tindie. WS2812B_preliminary.pdfWS2812B_VS_WS2812.pdf
  9. Created as part of GB#11, this booster pack uses 5050 RGB LEDs with integrated WS2811. Will post code examples later on. BTW, I cannot get a preview of this YouTube video to show up, can you check it out B#?
