DLP3030Q1EVM: Regarding DLPC120-Q1 Programmers guide

Hello Alex,

Thanks for the response.

Could you please help to share DLP3030-Q1PGU Schematics with us?

Thanks,
Sundar

Hello Alex,

Could you please help to share the document list attached in the image?



Thanks,
Sundar

Hello Alex,

Thanks for the documents.

We have a basic question.

Our understanding is we use SPI to control the brightness of DLP3030 as mentioned below.

PC/SoC-> SPI/USB to SPI->DLP3030 . Is our understanding correct?

Thanks,
Sundar

Hi Sundar,

Here is a quick overview of the connections. The connection between the PC and the EVM include 3 parts.

a.) USB B to USB A cable that goes from PC to Cheetah SPI Box

b.) Cheetah SPI Box which has a USB A port and ribbon cable female pins

c.) Cheetah to SPI cable #7 which connects the Cheetah Box to the Formatter board connector. 

You can use the control program under System Control under Dimming Control you can adjust the backlight value to change the brightness. 

Thanks,

Alex Chan

Hey alex,

Thanks for your reply

Kindly share me the BOM if its possible.

Hello Sundar -

I can answer while Alexander Chan is out of office.

For the DLP3030PGUQ1EVM key optical specifications, please refer to Section 1.3 of the User's Guide.

For the CHUD EVM, this product is being discontinued. Can you remind me what information exactly you are looking for?

Regards,

Ross

Hello Ross,

Thanks for the response.

We need the information as similar to DLP5530 document which is attached in this for DLP3030 as below

Please help to provide those information

Hello Alex,

Sorry, I Need Optical Parameter details of DLP3030, For that, I sent DLP5530 Optical Parameters as a reference in the 3 images.  We need similar information for DLP3030.


Please help to share the Optical Parameter Details of DLP3030.

Thanks,
Sundar

Hi Sundar,

My apologies for misreading the question. 

We provide the specifications in the user guides for the DLP3030CHUDQ1EVM which can be found here:

https://www.ti.com/lit/pdf/dlpu065

For specifications for the DLP3030PGUQ1EVM you can find the user guide here:

https://www.ti.com/lit/pdf/dlpu064

Hello Alex,
Thanks for the quick response.

Could you please help to share the part numbers of RED, GREEN, BLUE LED?

Also please help to share the electrical specification of DLP3030?(This information is not available in the above documents)

Thanks,
Sundar

I am a Chinese engineer. I want to use DLP3030Q1EVM circuit board and DLP3020AFQRQ1 DMD to form HUD. Is this scheme feasible? Is there such a solution on the market at present?

Hi,

I believe the scheme would be feasible I will need to double check but the overall block diagrams are identical between the DLP3030 DMD and the DLP3020 DMD. I do not believe we have a current solution on the market utilizing the DLP3020AFQRQ1 DMD.

What you may need to design is a new dmd interface board compared to what is currently offered on the DLPC3030Q1EVM (https://www.ti.com/tool/DLP3030Q1EVM?keyMatch=DLP3030Q1EVM). I have attached the schematic design of the dmd board as well which you can use as a reference.

Additionally may I ask your name and what company you are with and if you have any other questions please feel free to reach out.

Thanks,

Alex Chan

Helllo,Alex Chan

Yes, I have realized that making HUD with dlp3030q1evm circuit board and dlp3020afqrq1 requires designing an interface circuit. So what problems should we pay attention to when designing interface circuit?

My surname is Wang. You can call me Mr. Wang. I work in a company that produces optical and electronic related products.

Thanks,

Mr.Wang

Hi Mr.Wang,

I am looking into the schematic you had sent and will need some time to look it over. Thank you for your patience.

Have you ensured the DMD is securely connected to the interface of the dmd board. Snowflakes like what you are showing typically mean the DMD isn't properly connected to the socket/PCB. 

Thanks,

Alex Chan

Hello Alex,

Could you please help to provide access to download DLPC120

Hello Alex,

Thanks for the link and we were able to download.

Could you please help to share the display timing parameters of DLP3030? I have searched in documents but not able to find it.

Please help us on this.

Thanks,
Sundar

Hi Sundar,

Please see the following DLPC120-Q1 datasheet specifically sections 6.9 and 6.10.

https://www.ti.com/lit/ds/symlink/dlpc120-q1.pdf?ts=1656430947451&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FDLPC120-Q1%253Futm_source%253Dgoogle%2526utm_medium%253Dcpc%2526utm_campaign%253Depd-dlp-aud-prodfolderdynamic-cpc-pf-google-wwe%2526utm_content%253Dprodfolddynamic%2526ds_k%253DDYNAMIC%2BSEARCH%2BADS%2526DCM%253Dyes%2526gclid%253DEAIaIQobChMIsJv2i77Q-AIVCSdMCh38XwF5EAAYASAAEgIWYvD_BwE%2526gclsrc%253Daw.ds

Hello Alex,

Thanks for the reply.

Please go through this question and its raised by myself.

We have an issue with the setup as mentioned in the above question link.

Could you please help to clarify if we get 800x800 input to DLP will it crop to 800x480? Do you think TCON will do cropping of 800x800 to 800x480 and will work along with DLP 3030?

TCON with DLP3030 is possible? If yes please help to suggest TCON part number.

Thanks,

Sundar

Hi Sundar,

Sorry I am not sure what TCON is and the DLP 3030 will only support whatever video resolutions are listed in the datasheet.

Thanks,

Alex Chan

Hello Alex,

Regarding DLPC120 firmware programming, Is there any way to read the existing firmware from the EVM board using DLPC120 control program?

Thanks,
Sundar

Hi Sundar,

The DLPC120 does not support many options for reading the existing firmware from the EVM board. You are able to read some information like the calibration data but it is in binary format and is not readable.

Is there something specific you are trying to learn or access from the firmware for the EVM. 

Thanks,

Alex Chan

Hello Alex,

We are planning to design our own DLP3030 , for that we need to have provision to read and write the firmware on DLPC controller.

As of now write permission is there we can see.

Suppose if we need to read the exisiting firmware means how to do that? Please suggest.

Also , I believe we have only one firmware for DLPC controller and other components seperate firmware not required. Please clarify.

Thanks,
Sundar

Hi Sundar,

Is this other e2e ticket what you may be interested in. 

https://e2e.ti.com/support/dlp-products-group/dlp/f/dlp-products-forum/1104254/dlp3030-q1-tms320f2803x-piccolo-spi-and-dlpc120-spi-interface

There is a user guide with useful SPI commands that can provide all the necessary interfacing and communication.

Thanks,

Alex Chan

Hello Alex,

Thanks for the link, we will go through it.

Could you please help to suggest what is the minimum and maximum horizontal and vertical blanking period supported by DLPC120?

Because in the below question

https://e2e.ti.com/support/interface-group/interface/f/interface-forum/1112450/ds90ub941as-q1-symmetric-asymmetric-splitting-of-ds90ub941/4126334#4126334

the vertical blanking period is coming around 800-480=320, will DLP3030 accept that much vertical blanking period? Please help to clarify.

Thanks,
Sundar

Hi Sundar,

I am going to have to look into this further sorry for the delay and thank you for your patience.

Thanks,

Alex Chan

Hi Sundar -

The best way to determine if the DLPC120 can handle specific blanking periods is to simply test it with a physical setup. Do you have an existing setup?

The Parallel Interface Supported Resolutions table from the DLPC120-Q1 datasheet only provides typical timing, as this is all that we've tested. You may be able to provide input at timings that do not match the typical values inside this table, but we recommend testing it. Also, please refer to Note 3 from this table:

Ross
