Hello,

We need to change the exposure time in libdlpspec.dll, but we can’t compile it.

Can you please send us the link to what we need to download to be able to compile this dll.

We got the below errors messages.

dlpspec_scan.c: In function 'dlpspec_scan_read_configuration':

dlpspec_scan.c:342:5: warning: this 'if' clause does not guard... [-Wmisleading-indentation]

if (pBuf == NULL)

dlpspec_scan.c:345:2: note: ...this statement, but the latter is misleadingly indented as if it is guarded by the 'if'

if(dlpspec_is_slewcfgtype(pBuf, bufSize) == false)

dlpspec_scan.c: In function 'dlpspec_scan_read_data':

dlpspec_scan.c:554:5: warning: this 'if' clause does not guard... [-Wmisleading-indentation]

if (pBuf == NULL)

Thanks.

Hi Christian,

The DLP Spectrum Library is available on https://www.ti.com/tool/DLPNIRNANOEVM page: https://www.ti.com/lit/zip/tidcc49.

Once installed in default directory you should be able to compile the source files using the batch files located at: C:\ti\DLPSpectrumLibrary_2.0.3\src

Regards,

Akhil

Hi Akhil,

Thank you for your email. Our question was which compiler version shall we use to compile the library? We have tested several compilers, and we always got error/warning messages when compiling.

Do you know which compiler to use, which version?

Regards,

Christian

Hi Christian,

The DLP Spectrum library dll file is built using the mingw530_32 compiler installed as part of QT creator installation. You can see the same in "C:\ti\DLPSpectrumLibrary_2.0.3\src\buil_lib.bat" batch file.

Alternatively You can compile the library using Code Composer Studio CCS IDE using TI compiler v5.2.9

Instruction to setup the IDE are mentioned in the NIR Scan Nano EVM User Guide section C.https://www.ti.com/lit/pdf/dlpu030

Akhil

Hi Akhil,

Thank you for your email. We are now able to compile the dll file. However, we are now facing another issue.

We are using NIR sensor api library (nano-api.dll). We want to change the exposure time in configuration which I created in one of the functions that I call from nanoapidll.

I added my value to EXP_TIME enum and changed dlpspec_scan_get_exp_time_us() function (added case with my new exposure time value), built the dlpspeclib.dll but still when I create my config I do not get the expected value.

My guess is that I need to make modification somewhere else and some other switch-case statement returns 0 by default case.

Any suggestions on how to change the exposure time in the dll?

Regards,

Christian

Hi Christian,

Please ensure that the config file you have created is written successfully by doing a read of the same. Also Have you selected this config file to be the active one?

I believe you haven't made it as the active scan config. Hence you could not see your scan config changes.

Akhil

Hi Akhil,

Thank you for your answer. We are now able to change the settings. However, we are still not able to have an exposure time higher than 60 ms. Therefore, I asked a new question on this forum which is "Can you actually use an exposure time higher than 60 ms". I didn't receive any answer yet.

Thank you again for your help, you helped us to resolve 1 of your problems.

Regards,

Christian
