Hi and thanks again!
I had been considering the use of Mikal Hart's Flash abstraction layer... Doesn't this use flash memory? It seemed like a pretty elegant way to store a lot of data without much trouble.
My worries re: the size of the data packets eing transmitted has to do with my experience with serial communications pre 1.0 IDE. There, I could discern performance differences as a function of transmission speeds. What is the buffer size for hardware serial?
Thanks again for your thoughtful responses, I really appreciate them.
