Hi,
I am a design enginner working on TCA8418 keypad controller. we have interfaced a pic 24f processor with it . The i2c bus is pulled up with a 3.3 k pullup resistor and 1.5 k series resistor for voltage drop from 5 v to 3.3 v as the TCA8418 is a 3.3V IC and PIC24f is a 5v chip. Can any body help me as i am not possible to interface. Any source codes and design help would be appreciated.
Thanks & Regards
