thanks I'm reading the errata for the first time ... So there is no way to solve it... and I do not understand how to implement the so called "workaround" re-enabling the I2C clock.
In the other hand I try again with the internal RTC and the VBat pin connected to a 2032 battery and Again it does not maintain the clock. Im using the sketch included on the examples... another problem is that as I see it is not very accurate over time at least not as the DS1307.
So my solution is just do not remap the SPI1 and loose 3 ADCs. I suppose that I can use "4Channel 12-Bit I2C ADC Modules" to add more analog devices.
SPI Remaping and I2C
Post here first, or if you can't find a relevant section!
