From 36df1979f5c11d4e4dbe144b63f42390b6088f76 Mon Sep 17 00:00:00 2001 From: Matt Spinler Date: Thu, 25 May 2017 10:23:05 -0500 Subject: Add GPIO class This class is used for accessing a GPIO via the /dev/gpiochipX interface. It requests a GPIO line handle from the GPIO device to do the actual operation on. The GPIO number to use, for AST chips at least, is the actual GPIO number, such as GPIOA0 = 0 and GPIOA7 = 7. The class currently only supports writes.
