Subject: [PATCH, FT32] sim: character input port
Date: Mon, 21 Sep 2015 23:29:00 -0000 [thread overview]
Message-ID: <CA9BBF0458F83C4F9051448B941B57D119614F7E@glaexch1> (raw)
The FT32 simulator has character output, of course. This patch
adds character input, which lets the simulator run interactive
FT32 applications, e.g. language interpreters.
OK to apply?
sim/Changelog:
2015-09-21 James Bowman <james.bowman@ftdichip.com>
