I am developing camera system for a nano satellite (5kg)(a real satellite). I am going to use CMOS image sensor OV6620 for image acquisition
I intend to use USB micrcontroller to interface with this image sensor
1. The first approach: Using SiliconsLab C8051F340 (USB microcontroller):
This USB controller has I2C to control image sensor.
I have used I2C to sucesfully configure image sensor.
But , I am not sure how to capture image data from OV6620.
The output from OV6620 consists of:
- HREF: determine start of a frame
-VSYN: determine start of a line in a frame
-PIXCLK: determine pixel rate(8.8MHz)
-DATA[0-7]: 8 bit image data
The clock rate of OV6620 is 8.8MHz, so i need USB controller to capture these data and send to USB interface to computer(LinuxOS, Debian).
The clock rate of C8051F340 is 48MHz at maximum.
Could you guy address whether my C8051F340 can capture image from OV6620 and send to USB interface? and how to do that?
2. The second approach: using CYPRESS CV7C68013A USB controller:
I have heared that this USB controller is used to interface with image sensor OV6620. But again, could you guys have any experiences on this circuit before?
Thankx
