i2c question
PostPosted: Tue Nov 27, 2012 10:36 pm     Reply with quote
Hi, all.
First, sorry my poor English.

I have a question about #use i2c.

CCS version is 3.249.
I use PIC (PIC18LF4520) as slave.
I'm working on i2c communication between master(INTEL device) to several slave devices including PIC.

The i2c communication freezes occasionally when there is "SLOW" in #use i2c.
When I remove clock rate, communication is good.
But the checksum of two programs are same.

Doesn't checksum change whether I will remove "SLOW" in #use i2c or not?
Does operation change depending on a setup?

Could anyone tell me?

A _slave_ device, shouldn't have a speed at all.....
It is the master that controls the speed. Selecting a speed for a slave, can result in invalid configurations.

Best Wishes
