hello benj
is not that you can also find a bug on rs232 (see my post "flowcode v6 rs232 problem with atmega2560") the test you told me to do did not produce a positive outcome

The max baud with software mode is therefore currently fixed at around 500Kbps yet significantly faster than the previous 1.9Kbps.
Tested with same Atmega168 at 8mhz (without CKDIV) and i2C at 1mhz Software mode.
Wrote pages by 128 bytes 4000 times . It took around 60 seconds to write the memory. So it gives me around 68266kbit/s speed. Much faster than it was before, but not close to 500kbps.
I suppose this is because 24lc512 memory is working on 400khz even I set to 1mhz, but not sure.

PS: Will test FAT component soon.
