The 18F4550 has I2C feature. So i want to ask anyone know how to call th library provided for the chip? I want to interface it to 3 and more I/ expander. The I/Os are keypads (Input) and some output devices. Anyone ca help me please?
To call a library function, you must have a compiler.
How does _your_ compiler call library functions ??
There is I2C code on the MicroChip web site, but its in assembly code.
Good luck
