![]() For $50, you could probably get an USB in-system programmer from Atmel. Maybe the more expensive PCMCIA adapters would support I/O, but I don't think it's worth giving $50 for it (this one from eBay did cost $10 incl. To sum it up: the speed of the PCMCIA port is half the speed of a native port, which makes it still usable, pity it doesn't support I/O. ![]() (*) Estimate based on reading of the 512byte data memory - in other words, it just takes forever. SI Prog API takes 30-50 minutes* (20-35 bits per second) Laptop with a Gembird USB-RS232 adapter (identifies as Prolific chip) SI Prog I/O not supported - COM port grays out when selected SI Prog API takes 26 seconds (2520 bits per second) Laptop with a non-brand (eBay from China) PCMCIA-RS232 adapter: SI Prog I/O takes 5 seconds (13100 bps) ![]() SI Prog API takes 13 seconds (5040 bits per second) Here's my final report, all tests were performed by reading the 8kB program memory of ATmega8 and using a stopwatch.
