Hi All,
I'm having trouble with I2C. I am trying to communicate with a MAX6953, which is a 5x7 LED matrix display driver. I have had the device up and running with a Stamp, but can't get it to work with a PIC.
The PIC I am using is the 16F88. I am using the internal OSC at 8mHz. I am using portb.0 for SDA and portb.1 for SCL. I have tried using the DEFINE I2C_Slow.
Any ideas what could be causing the problem?
Thanks,
Jonathan
Defines should all be in UPPERCASE and ensure you check your SPELLINGS of them, as they may not flag errors in any compilation...

I2CREAD and I2CWRITE are really easy to fly with no issues providing you follow the rules in the PICBasic manual...

Please do check the FAQ's...
Melanie,
I had checked the FAQ, your posts and the book. The problem turned out to be (after mucho hair pulling) a bum PIC pin.
Thanks for the help tho!
