Actually I don't think there are 24C00 chips on DDC links. These chips only provide 128 bit (16 bytes) of storage space, which is insufficient to hold EDID data. So I think these are 24C01 chips (1 kb) which behave like the 24C00 as far as I2C addressing is concerned (i.e. answering to all addresses 0x50-0x57.) Apparently Atmel make such chips (the datasheet doesn't mention any I2C address, and the 3 EEPROM pins which are typically used for address selection are labelled "NC".) -- Jean Delvare _______________________________________________ i2c mailing list i2c-GZX6beZjE8VD60Wz+7aTrA@public.gmane.org http://lists.lm-sensors.org/mailman/listinfo/i2c
