From 6bf8000e6322da88f91f7eb53f510c2ba72743e5 Mon Sep 17 00:00:00 2001 From: Robin Haberkorn Date: Sun, 27 Jul 2014 16:23:23 +0200 Subject: added serial mouse driver for Microsoft and Mousesystems mice * Both drivers use the interface defined in serial_mouse.h * They should work with any UART implementation (hardware/software UART) * The Microsoft driver is currently untested. The Mousesystems driver is confirmed to work. --- protocol/serial_mouse_mousesystems.c | 140 +++++++++++++++++++++++++++++++++++ 1 file changed, 140 insertions(+) create mode 100644 protocol/serial_mouse_mousesystems.c (limited to 'protocol/serial_mouse_mousesystems.c') diff --git a/protocol/serial_mouse_mousesystems.c b/protocol/serial_mouse_mousesystems.c new file mode 100644 index 000000000..ec708c911 --- /dev/null +++ b/protocol/serial_mouse_mousesystems.c @@ -0,0 +1,140 @@ +/* +Copyright 2011,2013 Jun Wako + +This program is free software: you can redistribute it and/or modify +it under the terms of the GNU General Public License as published by +the Free Software Foundation, either version 2 of the License, or +(at your option) any later version. + +This program is distributed in the hope that it will be useful, +but WITHOUT ANY WARRANTY; without even the implied warranty of +MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
