Fernando,
Once again I need your help,since the installation of the last version of Ferduino, I have problem with date and time.
If I try to adjust to correct values, the data are not saved.
I have perform the test code for searching I2C device and the result was 1 device found at 0X20 from what I saw in the forum and in the test code for RTC , it should be 0x68.
In the previous version, it was requested to modify DS1307cpp and Henning H are those modifications still required ?
Could you give me some help
Thanks in advance
Jean-Yves

Hi!
Your RTC is connected on pins 20 and 21 so change this line on code:
On this case you can't use a PCF8575 without change RTC pins to 18 and 19.
Best regards.

Not exactly, all controllers with PCF8575 should use 18 and 19 to RTC.
