Hello sir ,

Actually i am interfacing ov7670 camera module with fx3

board,and for functioning ov7670 it requires external clock in mhz.so, i am

generating pwm on fx3 pin for which i have merged uvc code with that of

complexgpio.But ,the problem is only pwm part is working and a pulse of mhz

is generated on fx3 pin.but in device manager uvc is not appearing.. Below i

have attached my code,can you please tell where i have done mistake.

Thanks

Hello Manisha,

Upon using the descriptor file and the uvc related files that you have shared, I am able to find the device enumerating as a UVC camera. Kindly, recheck.

Best regards,

Srinath S

Hello Manisha,

Please share the descriptor file also. Also, mention if you have made changes to the firmware to suit the image sensor that you are using.

Best regards,
