DLP3010EVM-LC: DLP3010 EVM LC - is not recognised by GUI software + question about projection settings

Søren Hansen
Prodigy 10 points
Part Number: DLP3010EVM-LC
Other Parts Discussed in Thread: DLPC3430, DLP471TP, DLPC8445, DLPC6540

Tool/software:

I have a LightCrafter DLP 3010 EVM which has previously been set up by someone else. I want to do a horizontal flip of the image, which I understand from the GUI manual DLP® LightCrafterTm Display EVM GUI Tool Users Guide (Rev. B) (ti.com) should be possible. I have downloaded the LightCrafter GUI, but when I connect it to the device, the GUI just says EVM status: not connected. I don't know what I am doing wrong. Can you provide guidance on how to proceed? The computer desktop is projected by the EVM, so it is connected.

Secondly, I am seeking to do a horizontal flip, which I believe I can achieve under display > short axis flip. I am however also looking to project onto a curved screen, but when I do so, the more peripheral elements on my curved screen are distorted. Are there any 'corrections' I can apply to fix this?

    Hello Soren,

    Thank you for reaching out to us through E2E!

    Let me talk to my team about this, I'm not familiar with this Light Crafter GUI you are using. The guide you are referencing also seems to be a quite a few years old as well.

    Could you advise what version of software / firmware you are running?

    Best,

    Aaron

    Update, I've managed to get the connection going, but I have yet to solve the projection onto a curved screen. Any leads on this would be greatly appreciated.

    I have looked at the keystone mapping options in the GUI, but that seems to be more related to trapezoidal misalignment from angular projection to a flat surface. I'm think about geometric warping as a solution, but do the projector allow for such adjustments?

    Hello Soren!

    That's great to hear that you have it connecting! *Although I might be more confused now!*

    To start, I need to make sure that we're working with the correct board here because the DLP3010EVM-LC as you've linked to this thread is a Light Control (LC) device and has additional features that are not available on that Display version of the GUI.

    Could you please either:

    1.Perform a "Get" on the Information page of GUI and share what controller you are seeing

    OR

    2. Send me a photo of the EVM you are working with

    Additionally, please explain how you are planning to project to your curved screen? Is the projection path straight out or is it at an angle to the curved screen?

    Best,

    Aaron

    Apologies, I was confused about the model - the one I have is this one https://www.ti.com/tool/DLPDLCR3010EVM-G2

    For the projection, I am currently playing with either projecting straight onto the screen (but I would have to find a way to avoid the 'displacement' that is I guess built into the model, since the image is displaced somewhat upward and not straight onto the screen, or project with an angle. I'm playing the vertical offset, but haven't gotten anything that works yet. If you have any suggestions I'd love to hear them, but the curved screen distortion is my main focus Slight smile

    Hello Soren,

    I would recommend looking through the 3.3.7 Write Keystone Correction Control (88h) (link) of the DLPC3430 Software Programmer's Guide. This chipset only allows for 1D keystone correction, if you are in need of 2D and 3D keystone correction I would recommend our DLP471TP chipset (link) or our DLPC8445 chipset(link) (though we have not released an EVM for this chipset yet.

    Hi Maximus,

    Thank you for linking the guide!

    As I understand it, the keystone correction allows for correction if the projector is not aimed straight at the surface it is projecting onto, e.g. if the projector is placed at an angle (if the projector is pointing a bit upwards or downwards). For the 2D keystone correction, would that be if there is an additional angle left/right? And then 3D would that by a matter of depth  (so the projection angle is also dependent on depth - which I guess would be the case in my scenario, where the exact projection surface changes from the middle of the screen to the more peripheral sides of the screen).

    Is my understanding correct? And does that mean my current setup is not suitable for making the adjustments required to attenuate the distortion of the peripheral elements? And if yes, for the chipsets you mentioned, could those be combined with my existing EVM, or would I have to procure a new one (which you have not released yet)?

    Thank you for all your help.

    Cheers

    Hi Soren,

    1D Keystone: allows adjustments in pitch(angle up/down), throw ratio(distance from wall/screen size), vertical offset(offset up/down from projector optics). This is supported by the DLP3010G2-EVM

    2D Keystone: allows adjustments in pitch, yaw(angle left/right), throw ratio, vertical offset, and manual corner adjustment (determining an x/y pixel position for each corner. 

    3D Keystone: allows adjustments in pitch, yaw, roll, throw ratio, vertical offset. 

    In order to properly fit a curved screen you will likely need to use the Warping Features supported by the DLPC6540/DLPC8445 chipset as well. This level of warping/keystoning is not supported in the DLPC343x chipsets.

    Currently we have an EVM for the DLPC6540 which you could procure (link), we do not have an EVM for the DLPC8445 yet- this would require a custom board design to test with.

    Best,

    Max
