One guy's notes on his exploration of the Arduino open-source electronics prototyping platform
Will the library work with MCP79400 thru MCP79412
I believe so. If you try other devices in the family, I'd be very interested to know how they work out.I took a quick spin through the datasheets. MCP79410/11 should be no problem as the only difference is unique ID format. MCP79400/01/02 do not have EEPROM so of course those functions will not work. MCP7940M/N do not implement the unique ID and MCP7940M does not have the power-fail timestamp.
