That's one way. There are many ways to do something, it all depends on the materials available, on your skill set and what you're used to. Anything that works is a right answer.
I take it these are discrete LED's? Have you looked at LED strips and "intelligent" LED pixels? (WS2811 LEDs and WS2811 LED strips) Those items have PWM drivers built in. Also for BBB, look at LEDscape, it's a software package that runs RGB LED's. http://trmm.net/Category:LEDscape Read/research through all the LEDscape stuff you can. A lot of information is available, just not in a step-by-step format. You'll still need an interface to match the BBB's 3v pins to the 5 volts/12 volts needed for LED strips or Pixels. Making Arduino libraries work on BBB is an exercise for very advanced programmers, not a trivial task. -david On Thu, Jun 19, 2014 at 12:49 AM, <[email protected]> wrote: > Hi, I am programmer and new to electonics and BBB, so please be gentle > with me :) > > I have a project that involves controlling 48 RGB LEDS and want to be > able to control color and brightness and animation of the LEDs based on > other sensory inputs. eg changing colors, brightness and patterns when an > imput sensor detects a change in temperature > > After some searching around I have found the Adafruit 24-Channel 12-bit > PWM LED Driver - SPI Interface > here https://www.adafruit.com/product/1429 > > So I am contemplating getting 6 of these and chaining them together to be > able to control the 144 channels (3 x 48) required to drive the LEDs. > > My questions are : > > Is this the right way to go or is there a better way ?
