AFE4490 EVM

Prodigy 140 points
Other Parts Discussed in Thread: AFE4490

Dear all,

I bought a AFE4490 EVM, and try to get SPO2 data by using a AFE44x0SPO2EVM GUI.

I followed the step of quick start guide (http://www.ti.com/lit/ug/slau480c/slau480c.pdf).

Unfortunately, when I clicked Capture button, the message show that "Reading stopped without returning the expected number of samples. Please check the device and the inputs. Other error message show that " Insufficient number of samples for FFT calculation"

Any one have experience like that. Please help me to solve this problem. Thanks
