  1. Some time ago, I wrote about WS2812D, an 8mm RGB LED with built-in controller (WS2811.) However, that LED was killed off after very short run. Since then, APA Electronics came out with it's own version, APA-106, which is compatible with WS2811. I have 2 versions available in my store right now, 5mm and 8mm. They are perfect for any breadboarding or through hole project. I will be using them in updated versions of my clocks (Geek & Gear.)
  2. Hello! I know I've been posting loads of problems which you have all been very helpful with and I appreciate it. I'm at the last stage in my project where I have to send an image as a byte array (values from 0-255) via serial communication, use H/W UART to receive bytes and map them onto my RGB LED display to create the image. I've configured the UART at 115200 BAUD, clock at 18MHz, I'm using the UCA0 ISR routine to map the received bytes into a 3D array "image[8][8][3]" where the 1st, 2nd, and 3rd terms are row, column, RGB component, respectively. I am seeing results on the display whe
  3. Hi everybody, Hopefully someone will be able to help. The aim of this project is to send an image from my laptop over a serial port to the MSP430G2553 where the data will be processed and then the image will be shown on my RGB LED display. At present I'm looking at methods of converting an image into an RGB array. I found that using GIMP, a file can be exported as a ".c" source code file which converts the image into an array. - Although the syntax is unlike any I have seen before. Anyways, i am using a program I found on the web to do the sending of the data over the serial po
  4. Hi people! Basically I'm writing a function to control a 16x16 RGB LED matrix with serial communication. The function I'm writing requires an array of size 16x16 ( hueBuffer[16][16] ) and of type 'short' since the max value of hue is 359. However, I keep getting an error: "program will not fit into available memory. run placement with alignment fails for section "DATA_GROUP" size 0x23d" but there is plenty of memory on the G2553. I need the values of hue to go up to 360 so i cant use unsigned chars. Anyone know of a solution to this problem? I'll post the code if you wa
