'USB transfer data lack error' #98

Open hyoooo2 opened 5 years ago

hyoooo2 commented 5 years ago

I tried 'usb2 camera shield' and OV5642 camera. Installation usb driver on windows 8.1 64bits was successfully done. Open device '0 AU2S-1848-0018' / 'Load OV5642_JPEG_QSXGA.cfg' from usbtest.exe had no problem and it showed 'USB camera init success!' in a message box. But Click play button was failed with error message 'USB transfer data lack error'. SDK guide has no further explanation about this error message. I tried 32bit usbtest.exe. Same result. What is this error? How can i fix it?

I uploaded several config files in the guide : http://www.arducam.com/docs/camera-breakout-board/5mp-ov5642/software-guide/ please try it again. Thanks.

Thanks for quick response and configuration files. All of three configuration are working though 'USB transfer data index error' just after 'play'. But frame rate is terribly limited to 2-3 fps under only 'Display' option. I can hardly think my laptop(i7-3720qm, 16GB ram) has no strength to properly handle this streaming data. Any suggestion/help will be appreciated.

The RAW or YUV data is too big for USB2.0 port at full resolution. I am optimize the frame rate now, will keep update soon. Please be patient.

Using OV5642_RAW_2592x1944.cfg , add extra line REG = 0x3011, 0x18 or manually set from the GUI, you can get 8fps@5MP
