From 548331bbefc18d8667f9cc168fbe159f2daf1184 Mon Sep 17 00:00:00 2001
From: Nathael Pajani <nathael.pajani@ed3l.fr>
Date: Tue, 27 Sep 2016 23:33:55 +0200
Subject: [PATCH] Updated according to new ADC driver API Updated Comments
 Updated according to new header files Updated use of uprintf and UART*
 instead of snprintf + serial_write(0, ...)
