Excuse me for this late reaction. No time this week.
This nigth I wake up with a possible solution. I just forget the 2 pullup resistors on the SDCL en SDA pin. I tried it with a 24lc256 EEPROM to test the I2C bus. With 2 pullups its works and also the I2C clock.
Thanks again,
Henk.
Hi hendrikdutje,
The DateTime constructor exception in the netduinohelpers library looks like it is caused by invalid input. Can you step into the code and find the exact line which throws the exception?
