I am using the STSW-IMG501 software with the STEVAL-EVK-U0I1 evaluation kit and the STEVAL-56G3MAI1 evaluation board for the VD56G3 image sensor. I am trying to capture videos of my target application at high frame rates to assess the sensor propert...

I have the STEVAL-56G3MAI1 evaluation kit for the VD56G3 image sensor and the STEVAL-EVK-U0I1 to connect and take snapshots from the sensor. I have been looking into script generation and register setting and I would like to set the exposure time to...

I have gotten the following code to correctly validate CRC's, so I know I have configured the CRC correctly: uint32_t calcCRC = 0; hcrc.Instance->INIT = 0xFFFFFFFF; calcCRC = HAL_CRC_Calculate(&hcrc, (uint32_t*) pointer, length); calcCRC = HAL_CRC_Ac...

I see. I ran the sensor at a resolution 64x48 (minimizing how much the bandwidth will affect the software speed) and 88 FPS (the maximum limit for the GUI). I saved an image sequence of 10 frames as a .pgm file type and monitored the FRAME_COUNTER ...

Megane,Thank you for your response, this confirms my observations as well. I look forward to the release of your new SDK.Could you elaborate what you mean by using the frame counter in the metadata of the captured images? I tried looking at the Exi...

I think I figured out what it means by line equivalent. You can set the "Line Time" with the "LINE_LENGTH" register in section 13.2 of UM2602. The default and recommended value for the Line Time is 7.69 us, which corresponds to the extrapolated "li...

You were both correct, it has to do with output inversion. Eliminating the inversion prevented me from validating the CRC without also changing the CRC algorithm on the host device, so instead I can invert the output of the first calculate before fe...
