Today we'll be turning it up a notch and controlling 64 separate LEDs. Ok, there ARE 64 LEDs, but the Pi's GPIO doesn't actually have enough output pins to control that many pins individually. What's a hardware hacker to do?? https://pi.bradwood.com/blog/neo-the-led-matrix-has-you Sat, 18 Apr 2015 05:08:00 GMT brad@bradwood.com (Wood Brad) ColdFusion CommandBox GPIO Raspberry Pi https://pi.bradwood.com/blog/neo-the-led-matrix-has-you I know I promised to blog some more about how I set this blog up, but I've been too excited to to get playing with the GPIO (General Purpose Output)pinson my Pi. The input/output pins are what make the Pi really similar to my Arduino. They're the glue that allow hardware and software to really meet. Except on my Arduino, I must use C that's compiled to machine code and loaded onto a basic microcontroller. My Pi runs an actual operating system, so I can use whatever high-level language I fancy and bring whatever syntax and productivity I want along for the ride. https://pi.bradwood.com/blog/programming-the-raspberry-pis-gpio-with-cfml Sun, 12 Apr 2015 18:56:00 GMT brad@bradwood.com (Wood Brad) ColdFusion CommandBox GPIO Raspberry Pi https://pi.bradwood.com/blog/programming-the-raspberry-pis-gpio-with-cfml
