I2C EEPROM addresses conflict #66

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
The recommended I2C address table for the module EEPROMS is wrong.

It says that the UART is on the left bus, whereas it is on the RIGHT.

It says that the Ethernet/RTC is on the right bus but it is on the LEFT.

Their I2C address assignments give them the correct slave addresses but, being 
on the wrong buses, the UART conflicts with the LCD (right 81), while the 
Ethernet/TC conflicts with the VGA (left 82)

Suggested fix: re-assign UART to 82 and Ethernet to 81 and advise any users who 
have UARTs and Ethernet boards in the field of the new solder pad connections 
to make if they want to use the EEPROMs.

... and 81 cannot be used because t conflicts with the PCF8563 RTC chip ..
