Hello Peter,

I've already wrote the C code for the hardware I²C driver. It is tested for 89c66c familly and works fine.
I'm using it to dial with a RTC (DS1307) and an EEPROM (24C32).

Note that I've also wrote the code for EEPROM. Prety simple.

Go on my website to download the I²C code :
http://perso.wanadoo.fr/rs-rey/el...essources/
in the resources pages

and I can send you if required the code for EEPROM which is still not on the website.

If urgent, send me directly a mail.

regards
Stephane
