marfis 3 Posted November 8, 2013 Share Posted November 8, 2013 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 fading effect: IMG_1090.MOV any comments/extensions are appreciated.
