CL,

Thanks - I've had a look at the site/product - a bit pricey for me as only an occasional/hobby I2C user. The Australian magazine 'Silicon Chip' had an I2C analysis board as a do-it-yourself project about a year ago. It used pretty mendane chips and some free Phillips software; I must give it a go.

Can you run your system at 10MHz and see if that does the trick?

Please let us know when/if you get it going. I spent ages getting familiar with EEPROM I2C and would like to learn what the problem was.

Regards Bill legge
