Slowing Down ShiftIn/ShiftOut Clock Speed

Started by Andy Michalicek April 7, 2003
I am talking to a I2c device that is extremely slow (~20 khz). Is
there a way to slow down the clock used in the ShiftIn/ShiftOut commands?

Not unless you use a slower crystal or something. ShiftIn and
ShiftOut are set for fixed speeds.

If the BasicX is being used as the bus master then it has full control over
the buss speed. Just place some delays in the code.
