Beacon using 16 LED Neopixel ring and CY8CKIT-059 with DMA

thingiverse

I've included all of the files with this message. A beacon using an FC-102 Rainbow LED ring as light source that is made up of 16 NeoPixel LEDs. Print Combined.stl in a dark color, but print Diffuser.stl in a translucent material. I used a 0.4 mm nozzle and 0.2 mm layer height for the prints. Minimal infill (12.5 %) is included for Combined.stl through Skienforge 47, however, I recommend 100% for Diffuser. I also include the project file to run NeoPixel ring using a PSoC 5 on CY8CKIT-059 development kit that includes CY8C5888LTI-LP097 chip. This project uses custom UDB component incorporating DMA to remove typical CPU overhead, allowing up to 1000 NeoPixels in chain (provided you have necessary amps to power it). This UDB includes basic API with Start and Update functions and performs a DMA transfer from Cortex M3 RAM framebuffer whenever the update function is called, making this more general purpose where you might want to use NeoPixels. It also uses very little CPU time copying the frame buffer to the LEDs. I've added documentation to include it all for reference. Printer Settings Printer: CTC Replicator Dual Rafts: Yes Resolution: 0.2 mm Notes: Supports are not required in diffuser and should print it with 100% infill. The top section of the beacon (in combined.stl) has the inner cone surface coated in tinfoil to reflect the LED light to diffuser. How It Was Designed Very quickly put together in Moray for Windows, and exported to OpenSCAD through my export plugin that you can get by checking other "things" or sending a message.
