The download at https://www.mediafire.com/folder/4tov5s500gaif/camera_firmware_upgrade_images#qxwrid4bxkdey for firmware 1.43 does not work.

Can we get a new URL for this firmware? Is there a list of changes made in this firmware?

Thank you

@veye_xumm ok thank you. We'll try generating an external trigger and seeing how things sync up. We will follow up with more questions if we have any.

IMX287 - version is C 01.37 and L 02.04

We have 2 cameras set up for stereo vision. The primary camera triggers the secondary camera. The secondary camera sends a signal to the LED's to strobe.

I believe the triggers are not synchronized the way I expect.
I expect the primary camera and the secondary camera to have equal exposure and LED brightness. It seems the LED pulse is perfect for the secondary camera but does not line up with the primary camera.

My settings
primary: r trigger mode is 0
secondary: r trigger mode is 1
primary: r outIO1 mode is 0 - This is going to the secondary camera
secondary: r outIO1 mode is 0 - This is going to the LED's
primary: r expmode is 0
secondary: r expmode is 0
primary: r manual exp time 70 us
secondary: r manual exp time 70 us
primary: r current exptime is 59 us
secondary: r current exptime is 59 us

When I run the cameras at 500fps it looks close but the secondary is brighter.

At 300 FPS it gets worse

And at 100 FPS the primary camera doesn't capture any LED from the secondary camera

Here's an analyzer showing the trigger from the secondary camera is not equal to the primary camera. Even though the settings show it should be.

Will there be drivers for kernel v6.6 soon? Thank you

@veye_xumm Thank you for the quick fix. This worked perfectly for us. We can now synchronize our 2 cameras and an LED flash.

@veye_xumm said in GPIO Strobe pulled high during Video streaming mode:

k what model of camera you are using?

Thank you for the reply. We are using the 2 IMX287 for our prototype.

We want to sync the cameras in free run while also pulsing an LED during exposure.

We can not run our LED's 100% of the time because of power/heat issues. We only want to pulse them during frame exposure.

We are prototyping different cameras right now.

When GPIO1_OutSelect is Strobe and Trigger Mode is Video streaming, during Image Acquisition the GPIO is pulled high the whole time.

We want to 'strobe' our LED's only during the exposure. How can we achieve this while running at max fps mode?

Thank you

@veye_xumm I sent an email to sales@csoneplus.com. I have purchased an IMX287 for testing our prototype in the meantime.

@veye_xumm Thank you. I will contact the sales team for more information.

Thank you for the quick response to my question about the IMX287.

We are going to prototype a few different sensors. Are either of these sensors (IMX273 or IMX252) planned for the future?

The IMX273 has the same footprint as the 287. We are looking for more resolution than the 287.

Thank you
