Hi there,

I have waded through most of the i2c-related application notes, and sifted
through the PICLIST archives and found that all examples of master-mode on
PICmicros (that don't support master mode in hardware) implement the whole
i2c protocol purely in software. There are a million examples of
software-implemented master mode, but if you look at the datasheet,
Microchip says...

"All portions of the slave protocol are implemented in the SSP module's
hardware, while PORTIONS of the master protocol need to be need to be
addressed in the PIC16CXXX software."

This seems to indicate that you can use the hardware to do master mode -
IF - you fill in the gaps with software.

I have all the (hardware-based) code written for the PIC16F877 up and
running, but my application will ultimately be in a 16C73A or smaller
PICmicro. Hence the master mode problem. I also have all the code examples
necessary to do it in software, but I have very little code space left to
use.

My application is just the usual PIC to 24LC256 situation.

Have I missed an app note somewhere?. Has anyone done this?.
