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.
