DLPC300: DLPC300：The DLPC300 uses Multiple Bit Depth and Multiple Color Pattern Sequences

Hello Renzhen,

Welcome to the E2E forum and thank you for your interest in DLP® technology!

Can you say why you are not using a TMS320DM365? Is this due to unavailability?

We will likely not be able to get you the source code for the TMS320DM365 and possibly the FPGA, but we will follow up with what we will be able to support.

Regards,

Austin

Hello Austin Snyder,

Let me explain why I don't use TMS320DM365, because the circuit board in my hand is made by myself, not applicable to the standard sample bought on TI's official website, I do not add TMS320DM365 chip when I make my own sample, so there is no this chip, I only have FPGA, MSP430 and ST company's STM32 chip on the board I made, and I want to achieve Multiple Bit Depth and through these chips Multiple Color Pattern Sequences。

The product I plan to make is for 3D reconstruction, so I will use the function of Multiple Bit Depth and Multiple Color Pattern Sequences, and I will describe the pattern I need to project, and the pattern I need to project is monochrome, that is, blue, green and red are projected separately, and need a high frame rate. You see if there is any other way to meet the needs of the group me, thank you

I don't know if I explained it clearly！

Thank you very much for getting back to me

Hello Austin Snyder,

What country are you? I want to know what country you are in and the time of work, because I am in China, which is different from your working time, and I want to try to communicate with you when you go to work.

Hello Renzhen,

Thank you for the explanation.

The DLP3000 has reached end of life and we are no longer supporting new designs. I recommend that you consider designing around the DLP2010LC using the DLPC3470. 

Additionally, our DMDs are designed to be driven by our DLP controllers. I am unable to support you in the effort in controlling the DMDs by another means.

Kind regards,

Austin

Hello Austin Snyder,

Thank you for your answer! I know that the DLP3000 was discontinued, and my problem was not controlling the DLP3000 through other chips, but controlling the DLPC300 without using DM365 to implement Multiple Bit Depth and Multiple Color Pattern Sequences.
I have two questions for you：
The first question: if I use the template (DLPLIGHTCRAFTER) provided by TI's official website, is there a way to project the same number of different color patterns without DM365?
The second question: can technology explain where these functions can be found (LCR_WriteDLPCRegister(0xFF, 0x1000CC00), LCR_SetDisplayMode(LCR_DISP_MODE_PTN_SEQ), LCR_StartPatternSeq(0), LCR_WriteFPGARegister(0x318, 0x00), LCR_ StartPatternSeq(0x01)), or can you explain these functions to me, these functions I saw in the .lua file, this link mentions these functions :Creating Multiple Bit Depth and Multiple Color Pattern Sequences for the DLP® Li (Rev. A)

hello Austin Snyder,

Thanks for the answer!

 I have another question for you if I don't use DLP LightCrafter Control Software-5.0.0, is there any way to download images to flash. I found that the document only says to load four Splash patterns of 427*270 pixels into the firmware DLPR300PROM_v1.0.bin. Because this method only supports 427*270 pixels, I want to realize the function of Stored Pattern Sequence, so I want to download pictures to FLASH, I would like to ask whether to use DLP

LightCrafter Control Software-5.0.0 if there is another way to implement the Stored Pattern Sequence functionality.

Hello  Austin Snyder,

Thank you very much for your reply. Your reply is helpful to me，

I would like to ask you two more questions:
First question: I need to implement the Stored Pattern Sequence feature. I need to project whether the displayed image can also be downloaded to flash in the above way, because I see that the instruction manual downloads the image to FLASH through DLP LightCrafter Control Software-5.0.0 and then to DLPC300. Because the method you mentioned is to download the firmware to flash, there is no mention of pictures.

Second question: I downloaded .lua file (link:MBMC Sequences - TI.com) with the "MCMB Request" link, I want to guide what this Wenjia is for, what you are doing in making this file, and what the functions and decimal data in it mean (LCR_SetDisplayMode(LCR_DISP_MODE_PTN_SEQ), LCR_StartPatternSeq(1), LCR_ WriteDLPCRegister( 0x82,0x00 )，LCR_WriteDLPCRegister( 0xFD,0x00 )，LCR_WriteDLPCRegister( 0xFE,0x05 )，LCR_WriteDLPCRegister(0xFF,0x1000CC00)，LCR_WriteFPGARegister(0x318,0x00 etc.), and the link to this file mentions (link :Creating Multiple Bit Depth and Multiple Color Pattern Sequences for the DLP® Li (Rev. A)), but there is so little content that I haven't understood yet. So I would like to ask you.

Hello, Austin Snyder,

Thank you very much for your reply. 

You can also send me a link if you find similar forums, or if someone has discussed similar issues. Thank you very much.

Hello, Austin Snyder,

Thank you very much for your reply.

I have a question for you, can I use splash pattern (pixel 427*240) to do sequence mode, can I project as many bit planes as I want.

Hello Renzhen,

The DLPC30controlelr and DLP3000 DMD have been end of life. We strongly recommend switching over to current platform like DLPC3470 & DLP2010 or DLPC3478 &DLP3010.

TI advises against any new product development on discontinued devices and cannot provide /entertain any technical support/question.

Thank you for your understanding.

Vivek

Hello, Austin Snyder,

Thank you for your reply, because I still have chips in stock, so I need to continue to develop, otherwise it will cause waste and economic loss. If you can't help me, I'll think of other ways myself.

Thank you very much

Hello, Austin Snyder,

I was looking at the data manual（link：DLPC300 Programmer's Guide (Rev. B) (ti.com)） and found that the described registers were not complete, some registers were not written out. I would like to ask if there is a more complete manual describing the register operation of DLPC300。

Hello, Austin Snyder,

Thank you for your reply,When I looked at the msp430 routine code, I found some registers listed in the code, which were not specified in the data manual。So I wanted to ask you. For example, the following image is what I saw in the msp430 routine code, but did not find the corresponding instructions in the programming instructions
