    Hello user, 

    I used web tool to translate into English - hope the following translation is correct:

    "We are developing a small near-infrared spectrometer device, which uses the DLPC3470CZEZ chip to control the DLP2010NIR DMD.

    At present, we have not found the corresponding DLPC3470CZEZ firmware and source code. I hope to provide it, thank you!"

    The spectroscopy functionality is not supported on DLPC3470 controller. It is targeted for structured light application. The companion controller for Spectroscopy application is DLPC150 controller. Please this controller for your product.  The supporting firmware is available on the product page.

    The DLPC150 is pin compatible for DLCP3470, hopefully you may not make any changes to board.

    regards,

    但是DLPC3470的数据手册上有明确说明DLPC3470是支持控制DLP2010NIR DMD的.

    从DLP3470的数据手册书看，DLP3470是完全支持DLP2010NIR DMD的，所以应该有对应支持DLP3470控制DLP2010NIR DMD的固件和源码。你们在和相关的DLP3470和DLP2010NIR DMD的技术负责人再确认一下，谢谢！

    Hi,Vivek Thakur

    I'm very embarrassed about that sorry for sending the customer's Chinese content to the English forum by mistake yesterday because I was too anxious,Sorry for the trouble，thank you for your timely reply, I translate my customer's new reply,

    “However, the DLPC3470 data sheet clearly states that the DLPC3470 supports the control of DLP2010NIR DMD.

    From the datasheet of DLP3470, DLP3470 fully supports DLP2010NIR DMD, so there should be firmware and source code that supports DLP3470 to control DLP2010NIR DMD. Please check with the technical team of the DLP3470 and DLP2010NIR DMD to see if they can provide the information, thank you!

    “

    The above is the content of the customer's response，Please help him, thank you very much~

    Hello user,

    Unfortunately, we don't have firmware that support DLP3470 with DLP2010NIR DMD. Please refer to Vivek's recommendation above.

    我们公司的第一代光谱仪采用过的是DLP150控制DLP2010NIR DMD，但是由于DLP150的刷新速率不够，所以在第二代光谱仪上将DLP150升级为DLP3470；如果你们没有DLP3470控制DLP2010NIR DMD的固件和源码，那里们给我们提供一下DLP150控制DLP2010NIR DMD的源码和DLP3470控制DLP2010的源码以及开发环境，我们自己进行合并改造出DLP3470控制DLP2010NIR光谱的固件，谢谢！

    Hi，Lori

    Thank you for your reply，I translate my customer's new reply,

    ”Our company's first generation spectrometer used DLP150 to control DLP2010NIR DMD, but because the refresh rate of DLP150 was not enough, the DLP150 was upgraded to DLP3470 on the second generation spectrometer; If you do not have the firmware and source code of DLP3470 control DLP2010NIR DMD, can you provide the source code of DLP150 control DLP2010NIR DMD and DLP3470 control DLP2010 source code and development environment, we will merge and transform the firmware of DLP3470 control DLP2010NIR spectrum, thank you!“

    感谢，但是，以下这两个链接中资料，关于DLPC150和DLPC3470芯片本身只提供了编译后的固件，没有提供DLPC150和DLPC3470自身的源代码，现在我们要自己开发DLPC3470控制DLP2010NIR的固件，需要你们提供DLPC150和DLPC3470自身的源代码，以帮助我们完成开发需求，谢谢！

    Thank you for your reply，I translate my customer's new reply,

    Thank you, however,  the information in the following two links, about the DLPC150 and DLPC3470 chip itself only provides the compiled firmware, did not provide DLPC150 and DLPC3470 own source code, now we have to develop DLPC3470 control DLP2010NIR firmware, need you to provide DLPC150 and DLPC3470 own source code to help us complete the development needs, thank you!

    Hi Zhou Ying,

    The source code for DLPC150 is not open source and can not be shared. 

    Please let us know what is it you want to change in firmware and why .

    由于我们第一代光谱仪模块采用DLPC150控制DLP 2010NIR DMD模块，但DLPC150的刷新率不够，所以升级为刷新率更高的DLPC3470控制DLP 2010NIR DMD，从DLPC3470数据手册上看出DLPC3470是支持控制DLP 2010NIR DMD，但是从你们的技术哪里得到的回复是目前你们还没有DLPC3470控制LP 2010NIR DMD固件，所以目前要完成我们第二代基于DLPC3470升级版光谱仪的开发主要有两种方案，第一种就是你们定制出一套DLPC3470控制LP 2010NIR DMD固件给我们，第二种就是你们把相关源码给我们，然后我们自己定制开发合适的固件。我们的需求很简单，就是需要一个DLPC3470控制LP 2010NIR DMD固件，希望尽快能提供有效的技术支持方案，谢谢！

    Hi，Akhil Guntumadugu

    Thank you for your reply，I translate my customer's new reply,

    Since our first generation spectrometer module uses DLPC150 control DLP 2010NIR DMD module, but the refresh rate of DLPC150 is not enough, so upgrade to DLPC3470 control DLP 2010NIR DMD with a higher refresh rate, from the DLPC3470 data sheet, it can be seen that DLPC3470 supports control DLP 2010NIR DMD. But where to get the reply from your technology is that you do not have DLPC3470 control LP 2010NIR DMD firmware, so at present, to complete the development of our second generation based on DLPC3470 upgraded spectrometer, there are mainly two solutions, the first is that you customize a set of DLPC3470 control LP 2010NIR DMD firmware to us, the second is that you give us the relevant source code, and then we customize and develop the appropriate firmware ourselves. Our demand is very simple, that is, we need a DLPC3470 control LP 2010NIR DMD firmware, hope to provide an effective technical support solution as soon as possible, thank you!

    Hello Katherine,

    Thank you for your patience. I will summarize the complete response and help address the questions.

    1. The DLP controller along with-it accompanying firmware defines the end application. One DMD could be supported by multiple controllers to enable a different application or use case.  In this case, DLPC3470 along with DLP2010NIR  dmd chipset is designed for structured light application. This DMD combined with DLCP150 is designed for spectra sensing application.

    2. Spectral sensing firmware on DLCP3470 controller will not enable any higher performance. Customer should not compare the video frame rate supported on DLPC3470, which is applicable for displaying a video image.

    3. The 1-bit pattern rate is applicable for spectral sensing application.

    The spectral sensing application is supported only on DLCP150 controller.  Customer can easily reuse the hardware because DLPC3470 and DLCP150 are pin compatible.

    Best regards,

    Vivek

    我们发现DLP2010NIR DMD的接口采用的lvds形式，我们是否可以去掉DLPC3470或者DLPC150控制器，直接采用我们的CPU上集成的lvds显示接口接到DLP2010NIR DMD的lvds接口上，然后我自己在CPU开发应用程序直接驱动DLP2010NIR DMD以实现我们想要的效果，你们帮我评估一下这样操作是否具有技术可行性，谢谢！

    Hello Liuzaixing,

    I used the web translator to translate in English. Hopefully the following is correct translation:

    "We found that the interface of DLP2010NIR DMD adopts the lvds form. 
    Can we remove the DLPC3470 or DLPC150 controller and directly use 
    the lvds display interface integrated on our CPU to connect to 
    the lvds interface of DLP2010NIR DMD, and then I develop 
    the application program directly on the CPU Drive DLP2010NIR 
    DMD to achieve the effect we want, please help me evaluate 
    whether this operation is technically feasible, thank you!"

    The controller is required for reliable operation of DMD chipset.
     The interface between DMD and controller is sub-LVDS interface (proprietary) and we several layers of protocol.
    The controller takes the input pattern and translates them DMD mirror setting along with timing. You cannot replace them.

    Vivek

    "Thank you for your reply, but there is no substantive solution so far, I hope we will obtain the source code of DLPC150 and DLPC3470 by signing an NDA agreement, and we will develop it ourselves as needed, thank you!"

    Hello Katherine,

    TI does not offer source code any of the DLP controllers.  We cannot support this request.

    I would like to this discussion off0line (private) so that they can share their detailed requirement in detail, and we will explore best way to support their application.
