From 5925d146bc0457ad0955a939e50eff4c5fe131f8 Mon Sep 17 00:00:00 2001 From: px4dev Date: Sun, 21 Oct 2012 17:51:21 -0700 Subject: Move the tone_alarm driver out of the NuttX configs area and add it as an stm32-specific driver in the PX4 apps space. Add a new tone_alarm command that can be used to start/stop alarm tones from the shell. --- apps/drivers/drv_tone_alarm.h | 128 ++++++++++++++++++++++++++++++++++++++++++ 1 file changed, 128 insertions(+) create mode 100644 apps/drivers/drv_tone_alarm.h (limited to 'apps/drivers/drv_tone_alarm.h') diff --git a/apps/drivers/drv_tone_alarm.h b/apps/drivers/drv_tone_alarm.h new file mode 100644 index 000000000..27b146de9 --- /dev/null +++ b/apps/drivers/drv_tone_alarm.h @@ -0,0 +1,128 @@ +/**************************************************************************** + * + * Copyright (C) 2012 PX4 Development Team.

Patterns are ordered by + * priority, with a higher-priority pattern interrupting any + * lower-priority pattern that might be playing. + * + * The TONE_SET_ALARM ioctl can be used to select a predefined + * alarm pattern, from 1 - . Selecting pattern zero silences + * the alarm. + * + * To supply a custom pattern, write an array of 1 - tone_note + * structures to /dev/tone_alarm. The custom pattern has a priority + * of zero. + * + * Patterns will normally play once and then silence (if a pattern + * was overridden it will not resume). A pattern may be made to + * repeat by inserting a note with the duration set to + * DURATION_REPEAT. This pattern will loop until either a + * higher-priority pattern is started or pattern zero is requested + * via the ioctl. + */ + +#ifndef DRV_TONE_ALARM_H_ +#define DRV_TONE_ALARM_H_ + +#include + +#define _TONE_ALARM_BASE 0x7400 +#define TONE_SET_ALARM _IOC(_TONE_ALARM_BASE, 1) + +/* structure describing one note in a tone pattern */ +struct tone_note { + uint8_t pitch; + uint8_t duration; /* duration in multiples of 10ms */ +#define DURATION_END 0 /* ends the pattern */ +#define DURATION_REPEAT 255 /* resets the note counter to zero */ +}; + +enum tone_pitch { + TONE_NOTE_E4, /* E4 */ + TONE_NOTE_F4, /* F4 */ + TONE_NOTE_F4S, /* F#4/Gb4 */ + TONE_NOTE_G4, /* G4 */ + TONE_NOTE_G4S, /* G#4/Ab4 */ + TONE_NOTE_A4, /* A4 */ + TONE_NOTE_A4S, /* A#4/Bb4 */ + TONE_NOTE_B4, /* B4 */ + TONE_NOTE_C5, /* C5 */ + TONE_NOTE_C5S, /* C#5/Db5 */ + TONE_NOTE_D5, /* D5 */ + TONE_NOTE_D5S, /* D#5/Eb5 */ + TONE_NOTE_E5, /* E5 */ + TONE_NOTE_F5, /* F5 */ + TONE_NOTE_F5S, /* F#5/Gb5 */ + TONE_NOTE_G5, /* G5 */ + TONE_NOTE_G5S, /* G#5/Ab5 */ + TONE_NOTE_A5, /* A5 */ + TONE_NOTE_A5S, /* A#5/Bb5 */ + TONE_NOTE_B5, /* B5 */ + TONE_NOTE_C6, /* C6 */ + TONE_NOTE_C6S, /* C#6/Db6 */ + TONE_NOTE_D6, /* D6 */ + TONE_NOTE_D6S, /* D#6/Eb6 */ + TONE_NOTE_E6, /* E6 */ + TONE_NOTE_F6, /* F6 */ + TONE_NOTE_F6S, /* F#6/Gb6 */ + TONE_NOTE_G6, /* G6 */ + TONE_NOTE_G6S, /* G#6/Ab6 */ + TONE_NOTE_A6, /* A6 */ + TONE_NOTE_A6S, /* A#6/Bb6 */ + TONE_NOTE_B6, /* B6 */ + TONE_NOTE_C7, /* C7 */ + TONE_NOTE_C7S, /* C#7/Db7 */ + TONE_NOTE_D7, /* D7 */ + TONE_NOTE_D7S, /* D#7/Eb7 */ + TONE_NOTE_E7, /* E7 */ + TONE_NOTE_F7, /* F7 */ + TONE_NOTE_F7S, /* F#7/Gb7 */ + TONE_NOTE_G7, /* G7 */ + TONE_NOTE_G7S, /* G#7/Ab7 */ + TONE_NOTE_A7, /* A7 */ + TONE_NOTE_A7S, /* A#7/Bb7 */ + TONE_NOTE_B7, /* B7 */ + TONE_NOTE_C8, /* C8 */ + TONE_NOTE_C8S, /* C#8/Db8 */ + TONE_NOTE_D8, /* D8 */ + TONE_NOTE_D8S, /* D#8/Eb8 */ + + TONE_NOTE_SILENCE, + TONE_NOTE_MAX +}; + +#endif /* DRV_TONE_ALARM_H_ */ -- cgit v1.2.3
