Inputs
3.2. PHD50 inputs
The PHD50 has up to 8 analog inputs:
▪
GPIO1 through GPIO8
Analog inputs are typically used to read electrical signals that span a voltage
range.
Analog inputs GPIO1 through GPIO8 can also be configured as digital inputs with
wake-up functionality.
Additionally, inputs GPIO2 through GPIO6 can be configured as high-side, low
voltage/low current outputs.
The different configurations are done in software.
The PHD50 has 2 frequency inputs:
▪
GPIO9 through GPIO10
The frequency inputs are provided for the uses of a rotary encoder as an input
device. Both frequency inputs can also be configured as digital inputs.
