    I've used CCS I2C routines both hardware and bit-banged, master and
slave. Everything worked fine, always.

    Some months ago I've posted a msg on this list saying that I couldn't
made a serial EEPROM work at 400kHz, but found the error this week. I have
both SCL and SDA lines set as output (Me dumb, me dumb!) on the PIC. Setting
both as input solved the problem.

    Best regards,

    Brusque
