    superbrew got a reaction from reaper7 in [Energia Library] StellarPad EtherCard (enc28j60) library   
    Hi,
    I am able to get the testDHCP example working, but on others I get the following error:
    In function `abort': abort.c:(.text.abort+0xa): undefined reference to `_exit' collect2.exe: error: ld returned 1 exit status How do I fix that?
    I have tried different versions of Energia, I have replaced the 'cores' lm4f library, I have replaced spi.cpp and spi.h.
     
    EDIT: I figured it out, there is a commented section in startup_gcc.c
    __attribute__((weak)) extern void _exit (void) { } I uncommented and it is working fine now.

    superbrew got a reaction from abecedarian in LCD Demo   
    I have been working on some stuff with RobG's LCD backpack.
    Here is a short demo of my progress making a particle system and displaying a pciture. I know they are unrelated, but there is so much to do!

    superbrew got a reaction from bluehash in RGB Matrix slot machine game   
    I have made some updates to this project. I have limited the colors to 3, so that I can 'win' once in a while. Once I figure out to calculate odds and probabilities a little better, I will add some more colors. I also used one of the on board switches to initiate a spin.

    I have started to develop a slot machine based an 8x8 RGB matrix. I intend this to be a learning experience, and I am going to focus on the logic and control of the game.
    Hardware:
    Tiva C Launchpad
    TLC5947 breakout from Adafruit
    8 PNP transistors
    8 1k resistors
     
    As of right now, I have 2x2 sprites in 6 colors representing the symbols on the reels. Each 'spin', I populate an array representing the matrix with randomly chosen colors of sprites and place them in the matrix. Then I set a random number of rotations where the symbols spin and then slow down and come a stop. As of right now, all three reels spin and stop at the same rate, but I plan to update that to be more slot machine like. I also have not implemented any sort of win detection mechanism.
    Here is a short video, but it looks much better in person. The scrolling effect is much smoother and realistic.

    superbrew reacted to Foghorn in [Library] Six Axis or 6 DOF Complementary Filter   
    I've been working on getting the MPU-6050 up and running on the Tiva C and thought I might share the complementary filter library that I created. TI provides a 9 DOF DCM Complementary Filter, but it will not work unless you also have the magnetometer data to go with it. Anyway, hope this helps out anyone who might need to use it.
     
    Enjoy!
