I need a little help on coding i2c for a '73 it is required to interface with a 24LC01 to hold fixed constants (Havent used i2c before). There is also an RS232 interface required opperation reruired is 32 bytes from PC to PIC (via 232) then after verification to EErom (via i2c) these will be the opperational constants for the program. I can find enough reference material on the RS 232 but very little on the I2C section Any help / pointers / pitfalls would be appreacated....... Thanks Steve..........
