    VirtualEnder reacted to energia in LaunchPad on steroids, if you have a lot of spare time...   
    A huge difference big code space saver is that the LM4F120H5QR on the StellarPad has StellarisWare in ROM. Most of the low level configuration and such will be done using calls to the ROM code.
     
    Energia StellarPad edition is not yet read from primetime but we are getting there...
     
    Stay tuned.

    If you need alpha testers let me know, Energia for Stellaris will be BIG

    VirtualEnder got a reaction from bluehash in TM1638 Display Driver for Stellaris Launchpad   
    Here is a code library for a 7seg display/led/button module available cheaply on dealextreme. Code works well and I've found it useful, though I've had some trouble integrating it into other projects. Credit goes to Dan Oprescu (robotrandi <at> gmail <dot> com)

    VirtualEnder got a reaction from bluehash in Timer based Stepper driver   
    Hi all!
     
    The current project I'm working on with Stellaris is a stepper (step, direction) driver. I have these TB-6560 drivers that I got on eBay for cheap (here), and I've successfully driven the motors using the 32 bit timer. I've been able to set the frequency using a variable, etc, and hoping to implement acceleration, etc. The goal is to eventually write an entire gCode interpreter and be able to drive the CNC via a serial connection that dumps gCode to the Stellaris.
     
    I'm running in to a weird problem though. I'm attempting to add a control panel I got form Deal Extreme that connects via software SPI. I've been able to successfully interact with it using a library developed by Dan Oprescu. Works great in its own CCS project. I can read buttons, update the 7-seg displays, light LEDs, and everything works great. I've moved his library into my stepper project, and all hell breaks lose. As soon as I include the TH1638.h header in my stepper project I get hundreds of build errors. The really weird part is they don't seem to be coming from any of my code files. They are all coming from compiler includes in iosfwd and exception. I looked around on the web and I found something about including pre-compiled headers being a problem, but I'm a bit lost in this. I compared all the CCS project settings between the TM1638 project example, and my stepper project, and nothing seems out of place. I'm sure I'm missing something, but I have no clue how to debug this.
     
    If anyone has any ideas that would be greatly appreciated. I've attached my code so far if anyone has a few minutes to look it over! I'll keep posting here as I progress through the project as well! Suggestions and pointers welcome!
     
    EDIT (10-15-2012)
    Here's (attached) the latest updates to my code with the solutions listed below, if anyone is interested. I'll probably copy it over to github and then post it under the code section before too long here. I want to get it a little further before I do that. I'm sure I'm doing some things wrong here and I may have to change approaches, but this is what I've got so far!
     
    EDIT 2 (10-15-2012)
    Here is a link to the project git repo. Feel free to clone and code! https://github.com/VirtualEnder/Stepper

    It sounds like the battery voltage is not enough to power the MAX232. Try plugging in to a USB wall charger rather than battery power. Unless there is some specific need to use battery, it's much more reliable. I'm assuming since this going right to the printer it will be near an outlet.

    VirtualEnder got a reaction from SeuPay in AccelStepper Library   
    Thought everyone might like to know I got the AccelStepper (http://www.open.com.au/mikem/arduino/AccelStepper/) library working without any hiccups. I'm using a cheap eBay driver with a pretty beefy 3A Nema 23 stepper. Looking to build a CNC eventually. Just playing at this stage but it seems to work well with the launchpad. I'm running at setSpeed(1000) without trouble. I think the opto isolation on these chips is a bit iffy (get what you pay for) so fast acceleration seems to skip some steps, but that's manageable. Thanks again for all the work by the Engia guys!

    Support for StellarPad is on its way.. Give it another couple of weeks and a new release of Energia with StellarPad will be available.

    I like to share some pictures, (useful for your project docs).

    I hope they will be useful.
