Arduino & TimerCameraX - webcam examples just don't work

[jarkman]

I'm trying to use a TimerCameraX with Arduino, with the latest versions of everything.

Both of the Timer-CAM webcam examples (sta and ap) work for a little while, then become very intermittent, then stop delivering frames altogether.

Are these examples meant to work correctly with the TimerCameraX ? Should I be looking somewhere else for decent examples ?

Thanks,
Richard

Hello @jarkman

I assume you already have PSRAM enabled in your build, yes?

BTW: Not sure why but changing the frame_size from FRAMESIZE_QVGA to the camera native FRAMESIZE_QXGA helped a lot.

Thanks

@felmue - thanks. I had PSRAM enabled but perhaps not the right partition scheme.

I now have PSRAM enabled and I'm using the default partition scheme ('default 4MB with spiffs...').

I see it

• working with FRAMESIZE_QVGA (320x200)
• working but frequently blocking for several seconds with FRAMESIZE_SVGA (800x600) as in the original sample
• crashing instantly with FRAMESIZE_QXGA (2048x1536)

Any thoughts ?

thanks,
Richard

Hello @jarkman

I am afraid I am out of ideas at this point in time. Sorry.

Thanks
