  1. Also important, yeah. If one attempt times out, chances are the AVRDUDE process will still be running, and it'll need to be killed.
  2. You'll soon get a better answer from one of our chipKIT experts, but I'll chime in and say I had this same problem on my Macbook. From what I understand, it has to do with the somewhat odd way OSX works with the USB ports, the end result being that MPIDE wasn't able to send a reset signal to the board. My first workaround was to manually reset the board when programming. I'd tell MPIDE to upload, wait for it to compile, and as soon as it comes back with "Binary sketch size: ####" I'd manually reset the board (in my case, a Max32). That would leave the board in the right state at the right time and I could at least get it to program. Keith Vogel at Digilent & some of the folks at chipKIT looked into it, and all I can say is that as of the last time I grabbed a fresh copy of MPIDE the problem was solved, and I can now program my Max32 with no problems. Looks like I have MPIDE 0023 if that helps. -Norman
  3. Greetings! This is a project that I've been working on for a little while now, and now... well, it's dressed up for Halloween! I've been playing around with the (utterly awesome) WS2812 LED strips for a while now, with an eventual goal of semi-permanent lighting for the classier portions of my already classy abode. Using a Max32, a Basic I/O Shield, and MPIDE, I've been playing with various techniques & routines in order to control the lights as well as I'd eventually like. The first challenge was to get my sketch working with HSB instead of RGB. As a guy who plays with colors all the time, the idea of defining a color in RGB seems needlessly complex, but that's how the hardware works. My first efforts at doing on-the-fly HSB to RGB conversion are here: http://blog.digilentinc.com/index.php/controlling-led-strips-with-chipkit/ Once that was in place, I could focus on making cool colors, waves, etc. At this point I have a number of routines that look quite nice, and the below video shows one of my favorite. Yes, he's wearing a hat. What if it rains while trick-or-treating? https://www.youtube.com/watch?v=u4XjqhxhSx4
