![]() ![]() Hardware SPI is a little faster, but must be wired to specific pins // (Arduino Uno = pin 11 for data, 13 for clock, other boards are different). Check out the Adafruit Pro Trinket 5v for full stats. Default is DOTSTAR_BRG, so change this if you have an earlier strip. GPIO pins and Power RailsThe Renix Engine Monitor is Open Source and Mod. Your code just uses R,G,B colors, the library then reassigns as needed. The last parameter is optional - this is the color data order of the // DotStar strip, which has changed over time in different production runs.

By limiting the number // and color of LEDs, it's reasonably safe to power a couple meters off // the Arduino's 5V pin. ![]() This is a basic diagnostic tool, NOT a graphics demo.helps confirm // correct wiring and tests each pixel's ability to display red, green // and blue and to forward data down the line. Now that I was able to do that, I found this :D // Simple strand test for Adafruit Dot Star RGB LED strip. The other change I had to make was the configuration definition to BGR, RGB backwards. I had to change the datapin and clockpin, easy to find on the pinout site (. They probably focus on their python stuff more than on the Arduino IDE, which makes sense and all in all the Trinket still works with the Arduino IDE, so hurray :) You need to install the Adafruit_DotStar library, best done with the library installer. Since I couldn't find how to control it, here's my code how I did it. ![]()
