Grove RTC & Lego NXT

Hello,



I recently purchased a Grove RTC and I am encountering difficulties in communicating with this device.

I have installed the recommended 3 volt CR1225 Battery.

I have confirmed my wiring, tried with and with out 82k pull-up resistors.

I have tried wiring the RTC by itself and also with a pcf8574.

I am receiving an I2c bus error from the NXT -35 specifically.

The i2c address I have found on line or 104 or 0x68, is this correct?

The programming language I am using is Next Byte Codes.

I would appreciate any hardware suggestions you may have as this is the first Grove I2C sensor I have used.

Thanks Rick

Hi,



The I2C address is 0x68 , The problem is solved or did you still facing the problem?
