From 8053629c99f157e716a4560ef8d1e194d569d960 Mon Sep 17 00:00:00 2001 From: Scott Murray Date: Thu, 3 Jan 2019 01:10:01 -0500 Subject: libqtappfw: Add radio binding support Add initial support for the radio binding. At the moment, everything required for the current demo radio application is in place. Further development will be required to fill in support for changing bands and the stereo mode.
