Part Number: DLPDLCR2010EVM

Hello ! 

I have a few questions about the DLPDLCR2010EVM, if you please could help me, it could be very useful !

-With the graphic interface in this document : is that possible to load images and videos from our computer? In which format ? 1104.dlpu021b.pdf 

-What is the use of the MSP430 HDMI sample code ?

-I would like to blink the LEDs inside. Is that possible to control the LEDs with some commands ?

-Is it possible to save some images or videos in the memory of the EVM, in the aim of using the EVM later, without a computer ?

Thank you for your help,

    Soizic,

    Let me try to answer each of your questions individually:

    Q: With the graphic interface in this document : is that possible to load images and videos from our computer? In which format ? 1104.dlpu021b.pdf 

    A: This is the DLP LightCrafter GUI. As mentioned in the question below, it is possible to swap the splash screens used via the GUI. The system also displays video content received from the HDMI input, but this content is not stored permanently on the system.

    Q: What is the use of the MSP430 HDMI sample code ?

    A: The MSP430 installed to this EVM is used to assist with HDMI connections to most HDMI source devices (such as your computer). The MSP430 sends automatic I2C commands to the EVM chipset in order to configure the input source/resolution in accordance with the input detected from your HDMI source.

    Q: I would like to blink the LEDs inside. Is that possible to control the LEDs with some commands ?

    A: The current output of the RGB LEDs can be adjusted, or even turned on and off via I2C. A full list of available commands is available in the DLPC343x Programmer's Guide [ https://www.ti.com/lit/ug/dlpu020d/dlpu020d.pdf ]. These commands are also available in the DLP LightCrafter GUI, which is compatible with this EVM. You can download the PC GUI here [ https://www.ti.com/tool/DLPLCRD-GUI ].

    Q: Is it possible to save some images or videos in the memory of the EVM, in the aim of using the EVM later, without a computer ?

    A: Yes. Using the DLP LightCrafter GUI, you can swap the splash screens installed to the EVM. You can download the PC GUI here [ https://www.ti.com/tool/DLPLCRD-GUI ].

    Hello,

    Thank you for your help !

    I have a few others questions that come to my mind after your answer.

    -To save splash images, do I need a microSD for a memory on the EVM ?

    -I have seen that we can control LEDs in the GUI, thanks. But do you know if it's possible to turn them off regularly with some loops ? (in order to blink them)

    -In the page of the DLPDLCR2010EVM, I have seen the DLP2010-FW. What is the role of this tool ?

    Thank you for your time,

    Regards,

    Soizic

    Hi Soizic,

    The flash images can be saved onto the EVM memory provided they are not too large.

    We are looking into the ability to turn LEDs on and off. Are you attempting to program in a certain way to isolate certain colors or to flash the image entirely?

    Regards,

    Austin

    Hello ! 

    I would like to blink the three LEDs at the same time in order to flash the image entirely every second for example.

    Do you think it's possible ?

    Regards,

    Soizic,

    Using I2C commands, you can disable/enable all three of the RGB LEDs simultaneously. You would just need a host processor (such as an MCU) managing the timing on these commands. A full list of available I2C commands is available in the DLPC343x Programmer's Guide [ https://www.ti.com/lit/ug/dlpu020d/dlpu020d.pdf ].
