OK… I know this is a bit backwards, but i’d find it well useful! (and energy efficient!)
Does anyone know how to program say a processing sketch, that will integrate with fastspi, so that what i see on screen will be a good representation of what i would expect on the leds?
my guess is that it would be a bit like reverse engineering fastspi!
at its simplest, you set the number of leds, the type of led, and how long each row is, and then link to the arduino code and code away. what you code is sent to the processing sketch and you see it on screen, and when your happy with it, a couple of lines changed in the arduino code and pow, your leds shine the same way…
am i hoping, or is this actually a possibility?
Sounds like what you’re looking for is some kind of “emulator”, yes?
yeah, im looking at that, or maybe @Justin_Shaw 's little TIM module.
For a portable development rig, I’ve been very happy with an Arduino Uno and an Adafruit NewPixel Shield. http://www.adafruit.com/products/1430
It’s basically the same size as the Uno, and lies very flat on top of it. I keep an Uno with this shield in my bag; very portable. I have some of the TiM modules, and they’re bigger, which is good if you want that, and bad if you don’t. Depends on your work style, project needs, etc.
I used to carry a Rainbowduino with an 8x8 LED shield, but I think the Adafruit shied has pretty much replaced that for me in terms of small, portable LED rig for testing and development.
