Hi everyone, I am having problems communicating to multiple I2C devices on the same bus.

 

Here is the environment:

Windows 8.1 64

VS2013

Netduino 2 (with latest firmware)

NETMF 4.3.1

 

DS1307 RTC Module (VERY similar to this:  http://www.hobbyist....real_time_clock)

 

1602 LCD with I2C Backpack (http://yourduino.com...ct_detail&p=170)

 

I have tried a number of different libraries (sorry - at work atm, and don't have access to them).

 

Does anyone know the libraries I need that will work together to get this working?  Working code would also be perfect.

 

At this point I am considering connecting an Arduino to the LCD and talking from the Netduino to the Arduino when I want to display something (over serial), but that's an extra wire and shouldn't really be necessary.

 

Please note that I have the latest of everything (except VS 2014), and that seems to be the problem.

 

Thanks in advance

 

Dave

 

EDIT: 

The RTC is working by itself

The display and RTC work (together) from Arduino

The RTC has pullups for SDA and SCL

I have ported my 95% working code from Arduino because I have ran out of RAM there
