I am using the lpc1769 board witch is connected to the base board. I want to read out some datas from a device using I2C due to this i connected the device to the base board. I use the lpcopen I2C example for the lpc1769 board. The program debugs well and the main menu is displayed, but when i want to read or write datas to my device, i don't get any response. Actually i tip in the adresse of the device and the register number, and then nothing happens. For Information i have connected the device to the pins PI004 and PI005 (SCL and SDA connection) on the base board. Is this right or lies the failure in the software?
I hope someone can help me.

best regards
