From 7780fd1c01182ab67d899b78d85a0d3b0d89196f Mon Sep 17 00:00:00 2001 From: Mekaniserad Apelsin Date: Sun, 26 Apr 2015 08:08:54 +0200 Subject: [PATCH] Add mouse support to ADB Adding the makefile options ADB_MOUSE_ENABLE and ADB_MOUSE_ACCMAX. Might have gone overboard with comments, and tried but failed at not adding more than necessary outside the converter/adb_usb/ folder. --- converter/adb_usb/Makefile | 4 +++ converter/adb_usb/Makefile.pjrc | 4 +++ converter/adb_usb/matrix.c | 61 +++++++++++++++++++++++++++++++++ tmk_core/common/keyboard.c | 10 ++++++ tmk_core/protocol.mk | 4 +++ tmk_core/protocol/adb.c | 24 ++++++++++++- tmk_core/protocol/adb.h | 4 +++ tmk_core/protocol/pjrc.mk | 4 +++ 8 files changed, 114 insertions(+), 1 deletion(-) diff --git a/converter/adb_usb/Makefile b/converter/adb_usb/Makefile index a16873dc03..2369ee70ac 100644 --- a/converter/adb_usb/Makefile +++ b/converter/adb_usb/Makefile @@ -122,6 +122,10 @@ CONSOLE_ENABLE = yes # Console for debug(+400) COMMAND_ENABLE = yes # Commands for debug and configuration #SLEEP_LED_ENABLE = yes # Breathing sleep LED during USB suspend #NKRO_ENABLE = yes # USB Nkey Rollover +ADB_MOUSE_ENABLE = yes + +# ADB Mice need acceleration for todays much bigger screens. +OPT_DEFS += -DADB_MOUSE_MAXACC=8 # Optimize size but this may cause error "relocation truncated to fit" diff --git a/converter/adb_usb/Makefile.pjrc b/converter/adb_usb/Makefile.pjrc index b54ea142c5..c320c09d25 100644 --- a/converter/adb_usb/Makefile.pjrc +++ b/converter/adb_usb/Makefile.pjrc @@ -57,6 +57,10 @@ CONSOLE_ENABLE = yes # Console for debug COMMAND_ENABLE = yes # Commands for debug and configuration #SLEEP_LED_ENABLE = yes # Breathing sleep LED during USB suspend #NKRO_ENABLE = yes # USB Nkey Rollover(+500) +ADB_MOUSE_ENABLE = yes + +# ADB Mice need acceleration for todays much bigger screens. +OPT_DEFS += -DADB_MOUSE_MAXACC=8 # Search Path diff --git a/converter/adb_usb/matrix.c b/converter/adb_usb/matrix.c index 405391865f..6220ee6e1c 100644 --- a/converter/adb_usb/matrix.c +++ b/converter/adb_usb/matrix.c @@ -27,6 +27,8 @@ along with this program.
