Programming a DSP (a newbie question)

Other Parts Discussed in Thread: TMS320LF2406A, CCSTUDIO

Dear people, 

I have a TMS320LF2406A  DSP and Code Composer Studio v3.3, however I do not have any clue where to start. I have watched many tutorials but I cannot find any tutorials to solve my problem. 

I want to code in C language and do it from zero. In all tutorials, people are adding some files to their projects or doing something very different. Generally people using several kits however I do not have. 

I plugged xds510LC to my dsp and selected my dsp model from ccs setup. Then started the ccs and created new project. However, I do not know which configuration files I should load or where to find or what to write at the beginning. I want to make HIGH or LOW some specific gpios. Is not there any tutorials, blinking LED or something for me? I do not even know how to reach a specific output. Please help me.

    Hi Volkan,

    This device is  pretty old and I'm unsure whether the support is still available. Let me forward this to the C2000 team.

    Regards,

    A good source of information is the product page, in particular the Technical documents tab and the Tools & software tab.  There you can find a Getting Started document.  In addition, you will see information on the related evaluation module.  Such evaluation modules are a good intro to a product.  While you may not be interested in purchasing the EVM itself, such products often have examples that can give you ideas on how to get started on the DSP.

    You can refer this link which has sample codes both in C & Assembly:

    Check under: C24x Header Files tab

    I thank you a lot guys, however I cannot solve the problem. I have read the documents you sent but they do not give the knowledge I need or I could not find.

    Volkan, those are the only links available for the device. Also, those documents are enough to get you started. What else are you looking for? Step-by-step procedure? - Not available as this being a very old device.

    I am watching the tutorials for other devices, the closest device is 2407 and they are adding some header files (dsk2407.h) and adding linker and bios files. I do not have these files, how they get these? I am looking tutorials and for example in the code this "do the IO" part (on the screenshot), I do not know how to reach an IO or program IO as input or output. I am feeling like my brain going to explode, I cannot understand anything. Programming DSP is much harder than programming other hardware.

    Keep looking at examples.  For instance the Software Test Bench has a regs240x.h that has a lot of the registers mapped for you.  That might be similar to "dsk2407.h".  Additional examples can be found in your Code Composer 3 installation, e.g. C:\CCStudio_v3.3\tutorial\dsk2407.  You can find example linker command files (.cmd) there.

    If you are unfamiliar with microcontrollers, that is a big topic.  You might review the reference guide for your device.  There you will find a memory map.  The way a lot of micros work are that the various peripherals are "memory mapped".  That is, there is some address (or multiple) that represents a peripheral, and can be used to program that peripheral.  Toggling one of the bit of a certain address might set a GPIO Pin high.  This is what files like "regs240x.h" assist you with, they give names to the addresses so it can be easier to understand what you are programming.
