DLPNIRNANOEVM: Incompatible Software versions.

Part Number: DLPNIRNANOEVM
Other Parts Discussed in Thread: DLPC150

Dear TI community,

My team recently purchased the DLP NIRscan Nano EVM. During setup we reviewed thoroughly the information outlined in the User Guide and followed its instructions step by step. The latest versions of the GUI, Spectrum Library, Reference Software, and Firmware were downloaded and installed from the device's website. However, when we tried to use the spectrometer an error message informs us that the versions of the programs are incompatible (see the image below).

The procedure was repeated by several of us using different computers, and yielded the same result. Even though all the software packages were obtained from the appropriate links, and the installer files have the correct names, the Tiva SW and the DLPC Flash versions are not the newest ones. This problem is made stranger by the fact that the downloaded files have names that should correspond to the latest versions. In the following table I have summarized the names of the links that were followed, the names of the zip files, and the names of the installers. All seem to be correct, and yet we run into the same issue.

Name of the Link

Name of the zip file

Name of the installer file

DLP Spectrum Library Installer

DLPSpectrumLibrary-2.0.3-windows-installer

DLP NIRscan Nano GUI

tiidcc 47a

DLPNIRscanNanoGUI-2.1.0-windows-installer

DLP NIRscan Nano Reference Software

tidcc48a

DLPNIRscanNanoSoftware-2.1.0-windows-installer

DLPC150 Configuration and support Firmware

dlpc100

DLPR150PROM-2.0.0-windows-installer

That summarizes the first problem we encountered. To bypass it, we tried to instead use older versions of all the programs, so that at least they would be compatible and we could use the device.

We used the spectrometer on many different types of materials (ice, soil, aluminum, wood) and obtained nearly the same graph for all of them:

The shape of the graph (with varying levels of noise) was the same for all the samples analyzed, which clearly shouldn't be happening. To determine whether something was wrong, we used the spectrometer on a mirror to analyze Reflectance. We obtained values of Reflectance of less than 0.01, which also seems wrong. We assume that these issues are a consequence of using old versions of the programs.

In summary, we were unable to install the latest versions of the required programs, and when we used old versions the results were wrong. Does anyone know how to address any of these problems? Any guidance would be helpful.

Thank you for your time.

  • Hello User,

    Thanks for your interest in our DLP products, and welcome to the E2E forums.

    I'll take some time to figure out whether there is any issue with our latest installers and get back to you within a couple days. Thanks for your patience.

    Best Regards,
    Philippe Dollo
  • User,

    Thanks for your patience. I have had some time to investigate your issue.

    It sounds like you need to update the firmware on the EVM hardware itself, rather than downgrading the GUI software. Has the firmware update process in the Utilities section been successful on your end? Please refer to the NIR scan Nano EVM User's guide for assistance with this process.

    Let me know if you still need assistance.

    Best Regards,
    Philippe Dollo
