Apalis T30, WEC2013, MIPI CSI2 Camera, Capture, Preview

Technical Support

#1

Hello.

I flashed WEC2013 on Apalis T30

T20 / T30 WEC Software

Tegra WinCE Image (2.3 | 2019-07-10 | 61.49 MB)

Analog Camera <–> NEXT Chip N6 <–> MIPI CSI2 <–> Apalis T30 <–> WEC 2013

I confirmed that NEXT Chip N6 works well.(I2C Register read/write)

If I list the devices, there is no device called “CAM1:”

I’m wondering that Windows CE does have the CSI Camera Driver.

Do you have a detailed guide about this?

I need preview and capture camera image(s) with DirectShow or any other method.

Thank you in advance for the response.

Best regards, Bruce

Thank you for the response.

I already check that codes.

Error loading property bag.

I still need help desperately. Please help.

Hi @snswin ,

For Tegra Module there is no real Camera Driver. There is only a generic Capture filter and a customizable Camera Plugin DLL.

Take a looks at the sample code here:
https://developer.toradex.com/software/windows-embedded-compact/toradex-ce-libraries-and-code-samples#Sample_codes

NOTE: you need to adapt the Camera Plugin to match your CSI camera.

#6

Thank you for answer.

Previously, the project failed to load.

Let’s take a closer look at that code.

#7

Hi @snswin ,

Can you share the error you get on project load?

Did you follow all the installation instructions? You need to install the SDK, libraries and copy a folder to the right place before opening the project.

Also: there is a VS2015 specific project

#8

I followed build steps.

    1. Copy \CameraTegra\VSproperty directory files to \wincelib_bin_V2_0bis_2868(Windows CE software library directory).

Where can i find \CameraTegra\VSproperty directory?

#9

This is VS2015 load message. (CameraTegra_VS2015.sln)
It seems like I did not do build steps 4,5,6.

D:\Bruce\test-src\wec2003\camera\camerategra\CameraDemo.vcxproj : error : An exception was thrown while initializing part “Microsoft.VisualStudio.Project.VisualC.VCProjectEngine.VCLegacyEventsTranslator”.

Hi @snswin ,

Sorry, the documentation on the webpage is a bit inconsistent… it was written for an older version of the project where we distributed the vsprop files separately. Now they should be part of the library packet… but i just saw that for some reason they were not included.

Here a download to the missing files in the library package:

https://share.toradex.com/vd6bdtphbdqhxty

just use those files as a replacement to Item 4 in the instructions.

Hope it then works for you.
