From 53ff8a31b61952d9675558149d927f7942071df9 Mon Sep 17 00:00:00 2001 From: fredizzimo Date: Thu, 8 Feb 2018 22:07:46 +0200 Subject: Merge ChibiOS and LUFA descriptor support (#2362) * Move lufa descriptor to protocol/usb_descriptor * Try to compile usb_descriptor on ChibiOS * Add lufa_utils for ChibiOS Lufa USB descriptors for ChibiOS * More lufa_util compatibility fixes * First compiling version of shared USB descriptor * Send the usb descriptors * Fix the CONSOLE output on ChibiOS * Add errors for unsupported interfaces * Enable support for vitual serial port USB descriptors * Implement virtual serial port for ChibiOS * Cleanup the lufa_utils Use the default lufa header files * Add raw hid support for ChibiOS This is completely untested * Enable midi compilation on ChibiOS * Move midi functionality out of lufa.c * Don't register sysex callback when not needed * ChibiOS compilation fixes * Update ChibiOS submodule * Fix the Midi USB descriptor It didn't work properly when both Midi and Virtual serial port was enabled. * Add MIDI support for ChibiOS * Fix USB descriptor strings on ChibiOS * Use serial usb driver for raw hid * Generalize the ChibiOS stream like drivers This makes the initialization much more simple and eliminates a lot of the code duplication. * Convert console output to chibios stream driver * Fixes for ChibiOS update * Update the ChibiOS contrib submodule To include the usb data toggle synchronization fixes * Fix duplicate reset enumeration on ChibiOS * Add missing include * Add number of endpoints check for ChibiOS * Enable serial USB driver on all keyboards * Add missing includes when API is enabled withot midi * Add another missing inlcude --- .../protocol/midi/bytequeue/interrupt_setting.c | 15 +- tmk_core/protocol/midi/qmk_midi.c | 184 +++++++++++++++++++++ tmk_core/protocol/midi/qmk_midi.h | 9 + 3 files changed, 207 insertions(+), 1 deletion(-) create mode 100644 tmk_core/protocol/midi/qmk_midi.c create mode 100644 tmk_core/protocol/midi/qmk_midi.h (limited to 'tmk_core/protocol/midi') diff --git a/tmk_core/protocol/midi/bytequeue/interrupt_setting.c b/tmk_core/protocol/midi/bytequeue/interrupt_setting.c index eafef527c0..0ab8b54620 100755 --- a/tmk_core/protocol/midi/bytequeue/interrupt_setting.c +++ b/tmk_core/protocol/midi/bytequeue/interrupt_setting.c @@ -1,5 +1,5 @@ //Copyright 20010 Alex Norman -//writen by Alex Norman +//writen by Alex Norman // //This file is part of avr-bytequeue. // @@ -22,6 +22,7 @@ //implementations of the typedef and these functions #include "interrupt_setting.h" +#if defined(__AVR__) #include interrupt_setting_t store_and_clear_interrupt(void) { @@ -33,4 +34,16 @@ interrupt_setting_t store_and_clear_interrupt(void) { void restore_interrupt_setting(interrupt_setting_t setting) { SREG = setting; } +#elif defined(__arm__) +#include "ch.h" + +interrupt_setting_t store_and_clear_interrupt(void) { + chSysLock(); + return 0; +} + +void restore_interrupt_setting(interrupt_setting_t setting) { + chSysUnlock(); +} +#endif diff --git a/tmk_core/protocol/midi/qmk_midi.c b/tmk_core/protocol/midi/qmk_midi.c new file mode 100644 index 0000000000..d4de6caa7d --- /dev/null +++ b/tmk_core/protocol/midi/qmk_midi.c @@ -0,0 +1,184 @@ +#include +#include "qmk_midi.h" +#include "sysex_tools.h" +#include "midi.h" +#include "usb_descriptor.h" +#include "process_midi.h" +#if API_SYSEX_ENABLE +#include "api.h" +#endif + +/******************************************************************************* + * MIDI + ******************************************************************************/ + +MidiDevice midi_device; + +#define SYSEX_START_OR_CONT 0x40 +#define SYSEX_ENDS_IN_1 0x50 +#define SYSEX_ENDS_IN_2 0x60 +#define SYSEX_ENDS_IN_3 0x70 + +#define SYS_COMMON_1 0x50 +#define SYS_COMMON_2 0x20 +#define SYS_COMMON_3 0x30 + +static void usb_send_func(MidiDevice * device, uint16_t cnt, uint8_t byte0, uint8_t byte1, uint8_t byte2) { + MIDI_EventPacket_t event; + event.Data1 = byte0; + event.Data2 = byte1; + event.Data3 = byte2; + + uint8_t cable = 0; + + //if the length is undefined we assume it is a SYSEX message + if (midi_packet_length(byte0) == UNDEFINED) { + switch(cnt) { + case 3: + if (byte2 == SYSEX_END) + event.Event = MIDI_EVENT(cable, SYSEX_ENDS_IN_3); + else + event.Event = MIDI_EVENT(cable, SYSEX_START_OR_CONT); + break; + case 2: + if (byte1 == SYSEX_END) + event.Event = MIDI_EVENT(cable, SYSEX_ENDS_IN_2); + else + event.Event = MIDI_EVENT(cable, SYSEX_START_OR_CONT); + break; + case 1: + if (byte0 == SYSEX_END) + event.Event = MIDI_EVENT(cable, SYSEX_ENDS_IN_1); + else + event.Event = MIDI_EVENT(cable, SYSEX_START_OR_CONT); + break; + default: + return; //invalid cnt + } + } else { + //deal with 'system common' messages + //TODO are there any more?
