ST1VAFE3BX vAFE validation against reference signals

[bwilkins]

I'd like to validate ST1VAFE3BX vAFE measurement data against test signals as part of hardware design validation of a custom ECG sensor design based on ST1VAFE3BX.

I intend to input reference signals (differential or single ended) into the two bio channels of the ST1VAFE6BX, capture the raw ADC data, convert to mV, and then compare to the reference signals.

- Conducting this test will help validate the data processing, especially reading and interpreting vAFE data from the FIFO, which is different than if reading from registers.

Are there any documents or guides for how to do such tests?

Currently the vAFE waveforms I capture look correct except for the amplitude.

Hi @bwilkins ,

You can refer to our official examples on Github.

Hi @Federica Bossi ,

Thanks for the reply. I have seen the code. I'm after other details such as: description of test setup, input signals, ST1VAFE3BX configuration and expected results.

Other information:

- configure device in signal-ended configuration, or differential configuration?

- should I attach a signal generator to the electrodes directly, or via ECG pads?

Thank you!
