Bus Pirate Support / problem i2c TIMEOUT!
hello,
i have a big problem using i2c whit the buspirate.
it seems there is a long delay after a start condition and any ACK/NACK.
IT IS ALMOST 2mS long.
and it is getting even longer when the baud rate  of the buspirate is set to a lower rate.
normal i2c devises do not seem to care, sofar i could test it.
but i am trying to talk whit a smbus device, and that one does not like those long timeouts.
here a screenshot from my logic analyzer.

can anyone tel me whats is going on?
i am able to program the pic and i have the sours code open in mplab.
but i do not understand C/C++ completely.
can anyone help me to fix this problem?
