Hi,
Thanks very much for the reply.
The analog signal is from a laser scanner, profiling an object in detail, very quickly.
The PIC was going to read, store (in internal flash), read, store, read, store, etc. and then process the data when finished.
What do you reckon is the fastest speed I can get a 48MHz PIC to do this? Is there an ADC that will convert the analog signal at the fastest speed a PIC can realistically read the data (will be alternate clock cycles I guess - one for read - one for write - will the access time of the memory be longer than a clock cycle????)
I hadn't thought of a DSP - thanks very much for that suggestion. I'll research it - but would be very grateful if you could answer these questions as well.
Many thanks again,
Froskoy.
