Why does the fdc1004 evm breakout board not work when I separate it and wired it back? A screenshot of the GUI is included.

is there anything I am doing wrong?

thanks.

Scolion,

The EVM shows as connected, so you interfacing to the uC.
Please check your solder joints and confirm they are okay.
Also try selecting Autoread with a non-zero sampling rate on the registers page and check the Enable Continuous Multi-channel Measurements box on the Configuration page.
Hopefully that will get you going.

Regards,
John

John,

I notice that the evm keep going online - offline.

After I re-weld I2C interface, then it works. and the sensor plate works too. The i2c cable I used just 5cm, is this too long to occur this?

thanks.

Scolion.

Scolion,

I am not and I2C expert by any means, but I think 5cm should be okay.

John
