Hello,
I'm using an Arduino Uno Ethernet board that has a built in SD card reader. Pin 4 is being used to control the SD reader, pin 10 is used to control the ethernet controller.
Is there a third SS pin available to control a TTL Serial JPEG Camera? If not, is there another possible hardware solution?

Thanks,
Cris

ok this got me curious.
if the camera you described is TTL serial, then why you need another SPI chip select pin? I would think you just need rx,tx and gnd.

you are referring to this camera right?
