Subject: [PATCH 1/1] Input: ads7846: Add description how to use internal reference (ADS7846)
Date: Tue, 20 Oct 2015 11:05:00 +0200 [thread overview]
Message-ID: <1445331900-4978-1-git-send-email-alexander.stein@systec-electronic.com> (raw)
By simply setting vref-mv to 0 the internal reference will be used.
Document that!
