Post by thread:[PICLIST] Sharing Eeprom & DAC clock line problems

Hi, I have PIC12C671 which drives a 12-bit serial DAC and communicates with a 24LC01 serial Eeprom. Both peripherals share the same clock line. The DAC works ok, but Eeprom communication seems to be not working. I have a 4k7 pull-up resistor on the Eeprom data and the common clock line. Any ideas as to why the Eeprom doesn't like the shared clock ? (Maybe it isn't the clock at fault but i think everythig else is ok - i.e. wiring, control byte etc.) Regards, Darren -- http://www.piclist.com hint: To leave the PICList spam_OUTpiclist-unsubscribe-requestTakeThisOuTmitvma.mit.edu>

I've used this setup in several areas, and it always works. Unless you are using an Atmel I2C EE - they don't work all the time.
