Hi,
I'm trying to write a byte to an eeprom chip and read it back to my communication screen on hyperterminal. What I don't understand is that if you're performing a reading subroutine, do you set your PORTC,SDA as input so that the eeprom can send data(through a series of pulses 1s and 0s and so on throught it and communicate with the pic18? My question also being does it do this itself after you've fulfilled all the start conditions and control bytes and so on?
My current problem is that when I read from it(the eeprom), the SDA is always high and I can't figure out why is this?Any help?
and what is the importance of a capacitor on the eeprom chip,i saw some circuits on the net with capacitors ?
thanx in advance
ps; I'm using pic18f45k20 and programming in assembly language
