Dear all,

At GUI of FDC2214, I found 'Channel 0 Unread Conversion' at Device Status all of the time.

How can I cope with this?

Hello Yamamoto-san,

The device is continuously sampling. So shortly after you read the data, the next conversion is ready.

Dear Yibo,

In fact, we can get capacitance from CH0.

However, Device Status show 'Channel 0 Unread Conversion'.

Dear Yibo,

I found this at EVM which does not be redesigned.
So I think this is GUI's error...
Does this problem occur at you PC??

Yamamoto-san,

This is an issue with the GUI periodically requesting the register’s value from the EVM. If you communicate with the device directly (with MSP430 for example) this issue is not present.
