Controlling individual pins

[Seggan]

Is there a way to turn individual pins on/off? I thought maybe this would be it: RaspberryPiBoardInfoProvider.lookupByRevision(LocalSystemInfo.getInstance().getRevision()).createMmapGpio().gpioWrite()

Create an instance of com.diozero.api.DigitalOutputDevice (Javadoc). You then have access to on() / off() / toggle() / setValue(boolean) methods.

but what if i want to read and write from the same pin? im creating a class for a 4x4 membrane switch and i need to read value, switch pin modes, and then write

nvm found DigitalInputOutputDevice

4x4 membrane keypads should already be supported - see: https://github.com/mattjlewis/diozero/blob/main/diozero-core/src/main/java/com/diozero/devices/Keypad.java
