Hello, I am developing a biometric sensor prototipe using AFE4900.
The available documentation lacks info on internal registers/settings to select light pulses timing, drivers current and FIFO settings.
Moreover, the output data packets structure is unknown.
Could anybody provide me some further documentation?
Also, what is the LED driver internal structure? According to the datasheet there is a single ILED up to 100 mA, divided over four different output channels, but the maximum current is said to be 200 mA. Does it mean that only two LEDS can be turned on at a time, but EACH channel can sink up to 100 mA? If so, how can the ON sequence be decided?
Thanks a lot
