greyscale image capture at low resolution

[richarda]

I want to capture greyscale with a Video Experimenter shield on an Arduino Duemillenova at a 25×25 resolution, and then send that to a serial output (perhaps using the SoftwareSerial library)

Is this going to be possible? I don’t mind a bit of C programming but I’m not up to any assembly 🙂

thanks!

I’m afraid you can’t do grayscale without some very significant and complex assembly. And if you want to do serial communication, you need to use the pollserial implementation in TVout.

Ah. that’s a shame. Would it still require complex assembly if I limited my ambition to 2 bits per pixel? (ie. 4 shades)
