From bcb6adc5519801ca4032481aef4f64f0c28ec986 Mon Sep 17 00:00:00 2001 From: Alex Tereschenko Date: Sun, 26 Jun 2016 17:55:14 +0200 Subject: [PATCH] mock: added mraa mock platform infra and GPIO implementation Mock platform allows one to use mraa without having any real HW. This commit makes necessary foundational changes and implements GPIO functionality as well as adds respective tests.
