Hi Evert,
These two lines are just 10 lines under the I2cinit.
If I understand it well, the oscillator is working. By controlling the CH-bit (Bit7 Adres 00h) I can switch the SQW 1 Hz puls on and off
The DS1307 is recognised by the I2C-scanner.
Hope to receive new pcb with DS1307 tomorrow for exchange.
Regards Peter
