Hello all,
I'll be attempting to interface with a CCD, and I've been putting some thought into the memory requirements.
I assume I'll be using a 14-bit ADC, and the CCD is linear with 7500 pixels. Considering the data will be stored in 16-bit lengths, about 15kB of memory is needed per line. I'll further assume many lines will be read in a relatively short time, so it'll be impossible to fit everything in the internal SRAM.
What I think I need is external memory which I can use to quickly buffer the data until data acquisition is complete. The data can then be organised and sent to a slower, more permanent storage solution like an SD card.
I have never used any external memory with my microcontrollers, so I'm not entirely sure about what's involved. Does anybody have any thoughts on this?
Thank you!
