Control DLP Light Crafter Evaluation Module API with Matlab

Other Parts Discussed in Thread: DLPC300

Dear,

 I am using the DLP lightcrafter EVM. It works fine using the GUI.

I now want to control it through Matlab instead of the GUI. I have successfully compiled (using Matlab command mex)  LCR_CMD_SetDisplayMode( ( LCR_DisplayMode_t )( 0x00 )), so that I can just change the display mode from Matlab. For this, I needed to read the lcr_cmd.cpp file to see the correct function call, then I looked at the DM365 Comand Line Interface Document to see the value description.

So far so good, however....

For more complicated functions such as LCR_CMD_SetPatternSeqSetting, I would need a full description of the API. I want to know the sequence of functions that are called to achieve it, and the arguments that are passed to them.

 I cannot find a full API description or a more complete developer guide

 

Where can I find it?

 

Thanks a lot for your time, Pepe

    Hi,

    Are you currently using the DLPC300 programmer's guide? It can be found here: www.ti.com/.../dlpu004 (from the tech doc page: www.ti.com/.../technicaldocuments)

    You can also take a look at some code developed by another forum community member to interface the LightCrafter with MatLab: e2e.ti.com/.../200078. Please note that this SW is not provided or supported by TI.

    Thanks,
    Clinton

    Hi,

    Thanks for quick reply. I am actually using the DLP LC(TM) DM365 Command Interface Guide (1) TOGETHER with the (downloaded) dmd_interface project in C++ (2). For instance, in (1) section 3.2, I see current display mode and value description, but not the function use. So I then go to (2) and check the function call to realize that LCR_CMD_SetDisplayMode( ( LCR_DisplayMode_t )( 0x00 )) is the way to use it.

    For this simple example all is fine, BUT for more involved actions like projecting a set of recorded patterns, things get very complicated as I don't know the sequences of function calls, or the values they expect etc...

    I will have a look at the Matlab examples you pointed me to, may be things get clearer.

    Thanks for your help, Pepe
