The Context
I'm in the process of porting the libraries of Skywriter & Flick I2C gesture sensing boards from python to Java/pi4j. Both boards utilise the MGC3130 chipset.
The Problem
The MGC3130 chipset requires the transfer pin (BCM 27) to be used as both input and output within each polling cycle. At the start of the cycle the library waits for a low transfer line (input). However, the library then reconfigures the same pin (BCM27) as a low output to assert that the MGC3130 does not update data buffers before reading from them.
The Issue
Does pi4j-v2 support Multipurpose GPIO that can be reconfigured to work as input and output?
