#152812 - 6 FPS?
Responding to: ???'s previous message
Hi Andy,

The COMEDIA website quotes the frame rate for the C328R at 0.75~6 fps in preview mode @8bpp. I'm not really sure how that translates in terms of JPEG compressed image frame rate. They do ship a test application with the development board, and that puts out a pretty impressive frame rate connected directly to a PC. It's hardly video, though.

The C328R has a 115Kbps UART, so will go much faster than I run it at. I'm not sure how fast a standard 8052 can be made to communicate, but I could only manage to get 38400bps out of my AT89C51ED2. Thats the second bottleneck with the IP camera project, but is of far lesser impact than the delayed ACK throughput degradation situation. The IP camera actually runs pretty quickly as is with a client that doesn't delay ACK messages.

Thanks for the interest, Andy.

Regards,
Murray R. Van Luyn.
