  1. Hi guys, TI/Redhat has released the beta version of CC6 with Gcc 4.8 (as mentioned http://forum.43oh.com/topic/4500-msp430-elf-gcc-red-hat-version-available-in-ccs6-beta/ ) I was not aware if anybody has tried to compile those sources on the OSX platform.. So I tried and followed this path: 1) Download source files and header files from the TI webpage (msp430-130423-272-source.tar.bz2, GCC_RH_20131206) and remove packages that are not yet supported by the platform (GDB): tar xjf ../msp430-130423-272-source.tar.bz2 cd source/tools rm -r gdb tk tcl itcl sim libgui 3) configure
  2. Hi, here is a small project that runs on the MSP4305529 launchpad: https://github.com/hoihu/WS2812 that supports the 800kHz WS2812 LED strips (e.g. http://www.adafruit.com/products/1138 and others) by using the DMA controller rather than a while loop. The idea is based on the SPI approach by RobG: http://forum.43oh.com/topic/3971-wearable-ws2812-strip-controllers/ + work is delegated to DMA, frees foreground application (easier to code color changes etc) - needs app. 8x more RAM, as the LED bits must be deflated in advance in memory The main loop shows a nice looking color
