    OppaErich reacted to brainwash in TV Out   
    I had this idea after finding out there are no TV Out libraries for the Stellaris Launchpad. Well, after two days of hair pulling I can almost imagine why. It's very hard to do timing accurate things on this uC and a lot of unknown stuff gets in your way.
    I got pretty far with the implementation, I'll have to see if I will do some more with it. Rather, I'm hoping that the community will chime in and support this feature, so if there is enough interest and able coders we might set up some some source community project (google code / github / sourceforge / ...).
    Problems:
    - some white streaks on the sides, caused by some peripherals. I'm using only two resistors as "the hardware" so they might pick up some noise from uC.
    - slight vertical jitter. This is kind of expected because I did not want to do loop counting
    - oscilloscope loses sync sometimes, this means that timing is off
    - no double buffering. I'm using a large array (~21k) as a buffer and it's not packed at all
    - code style: I'm pretty new to the embedded world so I appreciate any kind of feedback you have to offer. I might have reinvented the wheel in some places
     
    It's a flickering bouncing box.
     
     
    Any contribution is appreciated, I can provide the hex file if someone wants to try it. It has only been tested with a small beamer.

    OppaErich reacted to Rickta59 in CCS V5.2 Linux and Stellaris Launchpad .. interesting find   
    I came across this post on the e2e.ti.com forums:
     
    http://e2e.ti.com/su...486.aspx#680486
     
    It talks about another TI eval board that seems to have the same USB PID/VID as the Stellaris launchpad.
    (1cbe:00fd Luminary Micro Inc.)
     
    So hoping for the best, I created a file named:
     
    /opt/ti/ccsv5/ccs_base/common/targetdb/connections/Stellaris_ICDI_Connection.xml
     
    and stuffed this into it:

    <?xml version="1.0"?> <connection id="Stellaris In-Circuit Debug Interface" class="31040"> <connectionType Type="LM_ICDI"/> <property Type="hiddenfield" Value="No" id="dataFileRequired"/> </connection>
     
    (/opt/ti) is my installation directory, you might have to change the location if you installed someplace else.
     
    I followed the hints in that e2e post and ended up with a working CCS V5.2 under ubuntu 11.04. I restarted CCS as root and saw that there was a new connection type "Stellaris In-Circuit Debug Interface" in the General section of the project properties. I had to install and monkey around with the libraries mentioned in the post. Once it stopped complaining about missing libraries, I imported the workbook labs and was able to compile, download and debug on linux. Yay! I probably should add a udev entry so I can run as a regular user.
     
    I'm still very interested in a command line openocd interface to the stellaris launchpad. Until that appears, at least I don't have to run windows or a virtual machine to get a working linux development environment for my Stellaris Launchpad.

    R2, R7, and R9 are shorted. If you want to use memory HOLD or backlight resistor, cut the traces.
    J3 is also shorted for use with USCI (P1.7 MOSI, P1.6 MISO.)
