ey ey!
I have a question. I am very bad in comparing specifications, but over time I saw that most of you are using Teensy to drive your projects.
Could somebody explain why is Teensy the favorite controller?
With a Teensy you have (compared to Arduino AVRs) more RAM, more Flash, more MHz, more everything… and an ARM architecture.
It´s like comparing a streetfighter motorcycle with a bicycle.
Arduino offers ARM boards too, but they are way more expensive.
Thanks Stefan!
and we need all this power to drive Led´s? Where can I read more about this so I start to learn which are in reality the resources needed by Leds and Fastled Library?
With just a bunch of leds you are fine with an Uno or even weaker hardware (like ATtiny). I would say 256 leds is the limit for an Uno before you spend more time with optimizing code than with writing code.
So it´s basically a question of the amount of leds you are going to drive, the complexity of your animations and the desired fps you want to see.
The Teensy is also much smaller then an Arduino UNO or Mega (for example) so easier to fit into smaller projects. The Teensy is also by an independent developer (a really great guy!) and I’m happy to support his product.
You don’t necessarily need a Teensy to drive LEDs. There’s a variety of options. It really depends on the complexity of your project and what you’re trying to do as to how much controller (or lack of controller) you might need.
excellent guys. thank you very much. it is very clear and helpful.
I started driving addressable led strips with a mega with the “digital light wand” project from Mr ross (http://mrossphoto.com/wordpress32/lpd8806-dlw/). Slowly I am starting to use other arduinos such as flora and even micro, but for very little projects, which seem to be more than enough. But soon I want to start playing with bigger set up´s and it is always very nice to see what is the community on to. I also bought recently a ts1000 controller to check out how it works.
