commands over I2c bus
PostPosted: Fri Jul 31, 2009 3:43 am     Reply with quote
Hi

I am new to i2c and have finally got two pic's communicating (one master the other slave). Eventually I want to create an i2c lcd interface.

What I would like to know is receive strings from the master. I can receive bytes but don't know how or if its possible to receive strings.

Strings, _are_ bytes.....
All a 'string' is in C, is a sequence of ASCII bytes, terminated by a '0'. Hence it is commonly referred to as a 'null terminated byte array'.
Such a sequence, can be sent over I2C, just as easily as any other byte sequence.

Best Wishes
