Minimalist description: RS-232 byte serial input {4800 baud needed, higher speeds desirable} 10 MByte non-volatile memory Byte serial output {USB preferred, RS232 acceptable} LOW cost
Minimalist operational description: Operator choses record/playback before applying power/start If in: record mode data appended to existing data playback mode all recorded data dumped Operator may chose reset which erases _ALL_ data and resets any internal pointers to "zero"
-- These erasures should occur no more frequently than once or twice per day and presumed unit useful life not presumed to be more than 3 yrs.
What I envisage:
A system with UART and NOR Flash with FPGA for "glue logic" Erasure times of "few" minutes would be acceptable
My personal application: Input would be from a GPS mouse receiver. Once a day I would dump data to my PC, followed by erase cycle. I'm assuming a receiver giving updates once/second.
I've found products that come near (if not close) but they insist on Bluetooth which is *UNACCEPTABLE* to me. Others are too volatile.
Suggestions? Thank you.
