    Energia Latest Releases

    This is awesome. Works great on my LM4F120XL! The only thing I miss is that Code Composer Studio (and probably other Stellaris Launchpad toolchains) have on-board debugging. Is there any chance this could be implemented in Energia eventually? Alternatively, is there an external tool I can use to do the debugging (breakpoint, step, watch variables) after I build the code with Energia?

    Quadrature Encoder Interface on Launchpad?

    Veimmone, that sounds fantastic! I will PM you my e-mail address. For my purposes I am interested in velocity measurement, but your source code still might be a good starting point.

    Quadrature Encoder Interface on Launchpad?

    Thanks guys, that's very helpful Dexter, if I am interfacing with two quadrature encoders simultaneously (each on their own pins) will interrupts still be okay or will I need to be using a RTOS?
  6. I am thinking of using a Stellaris Launchpad (LM4F120XL) as a robot controller. If I had something like this (http://www.pololu.com/catalog/product/1551) how would I go about interfacing with the quadrature encoders? This TI webpage says "Advanced motion control capability, with up to 16 PWM outputs and two quadrature encoder interfaces" but I cannot find the terms "quadrature encoder" or "QEI" in the Launchpad manual. Am I going to need to learn the gritty details of quadrature encoding and write my own C interface? I am very new to all this, so a gentle shove in the right direction would be awesome.

    What does "stackable" mean for headers?

    Thanks, that makes sense.

    [Ideas] Okay this is cool and now?

    Maybe you could put a Wi-Fi dongle in the Pi, then you can SSH into it and program/debug wirelessly.
  10. Beginner's question here: The Stellaris Launchpad has "stackable headers". What does that mean? Does it mean I can use more than one Booster Pack on the same Launchpad? I would think that each pin could only act as one input/output, so what would be the purpose of "stacking"?

    Hello, World!

    Hey guys! I'm a 21-year-old guy from Washington, USA. When I was about 9 or 10 years old I took a robotics class and a computer programming class at our local home school academy. I found both extremely fascinating! Today I am a programming intern at a software development company, and I love it. But I have not done much in the area of electronics or hardware hacking since those early years, and I would like to get into it as a hobby. Right now I don't have any solid project goals, I just want to learn and tinker. I have a Stellaris LM4F120 and just recently got up and running with the blinking LED example. The on-board debugging feature is really neat! I look forward to asking you guys all sorts of stupid questions Happy hacking!
