OpenVG examples for IMXRT1160

[simenga]

Hello,

I created a SDK with the IMXRT1160 and OpenVG. The header files for OpenVG and the respective libraries are there, but I can't find any example code. I'm specifically wondering how to create a context to start utilising OpenVG. From googling, I can't seem to find any examples on how to use the API on a microcontroller setting.

Thanks

Hi @simenga ,

The OpenVG example is at \SDK_2_12_0_MIMXRT1160-EVK\boards\evkmimxrt1160\openvg_examples.

It only has IAR and gcc project.

API document can be downloaded from https://www.khronos.org/registry/OpenVG/specs/openvg-1.1.pdf

Thank you. Do you know if there is any possibility to utilize OpenVG for drawing directly to a frame buffer without a display? My use case is that I want to do gaussian blur and convolution on a image placed in RAM without necessarily writing it to a display. I just want to use the GPU to accelerate image processing.

Seems like the library also is tightly coupled with FreeRTOS, with linker errors occurring if it isn't linked during compilation. Is there a way to circumvent this?

Hi @simenga ,

Sorry I don't know.

Are there any application notes or documentation out there for this specific case, or someone I can contact? There must be someone who've worked on the chip who knows.

Hi @simenga ,

The official is to ask Vivante for these materials like Vivante OpenVG API, source code, etc.
