    The real problem arround here, is the interrupt routines definition in the startup.gcc
     
    I have been fighting for 2 weeks with Energia, trying to enable the timer 0 and the interrupt based ADC. But when I declare the interrupt functions on the startup.gcc file, the code compiles without problem, and its loaded into the stellaris without errors, or freezings, like the ones that brownfox is having.
     
    My code idea was to sample a signal at full speed (1Msps) and have a constant clock signal at 1hz, all interrupt based. Actually Im sampling at 950Ksps, filling a 2048 samples block, without DMA. Im trying to make a DSO like board for my laptop, so its a good start. 
     
    The code, and some explanation (spanish post, so open google translate in a new window  ) is in this url http://patolin.com/blog/2013/05/16/stellaris-launchpad-y-energia-programando-un-cortex-m3-facilmente/
     
    Honestly, using CCS for the stellaris, was not so funny for me. I dont like eclipse, and its pretty slow in my not-so-top-notch laptop, so Energia makes the things more easy for me, and I think that it will help more people to use the launchpads
