- * GPS Plugin for lcd4linux, by michael vogt / http://www.neophob.com
- * contact: michu@neophob.com
- *
- * based on nmeap by daveh, http://www.dmh2000.com/ or http://sourceforge.net/projects/nmeap/
- * you need a compiled libnmeap to compile this plugin.
- *
- * History:
- * v0.1 -initial release
- * v0.2 -fix include files, include <termios.h> and <asm/fcntl.h> (embedded devices)
- * -fixed emulation mode (read only x bytes instead of the whole emulated nmea data)
- * -improved error handling (if there are no parameters defined, lcd4linx will display "GPS ARG ERR")
- * -display raw nmea string from the gps receiver
- * -added support for gps device with 9600 baud (env. variable)
- * -added the option that the widget graps data from the buffer and not from the gps device (usefull for multible widgets)
- * v0.3 -improved nmea parsing
- * -improved gps-emulator
- * -time is now updated with rmc and gga sentence
- *
- * TODO:
- * -update direction only when speed > 5 kmh
- * -add more data fields
- * -dump nmea string to external file
- *
- * Exported functions:
- * int plugin_init_gps (void) - default plugin initialisation
- * void parse(SHOW-OPTIONS, DISPLAY-OPTIONS)
- * display option define, what the plugin should display
- *
- * OPTION: EXAMPLE:
- * ------- --------
- *
- * PARAMETER 1:
- * #define SHOW_ALTITUDE 0x000000001 alt:500
- * #define SHOW_SPEED 0x000000010 spd:30
- * #define SHOW_COURSE 0x000000100 dir:NO
- * #define SHOW_SATELLITES 0x000001000 sat:4
- * #define SHOW_QUALITY 0x000010000 qua:1
- * #define SHOW_STATUS 0x000100000 sta:V
- * #define SHOW_TIME_UTC 0x001000000 utc:113459
- * #define SHOW_DATE 0x010000000 dat:190204 (19.02.2004)
- *
- * PARAMETER 2:
- * #define OPTION_NO_PREFIX 0x000000001 disable prefix (example, instead of "alt:500" it displays "500"
- * #define OPTION_SPEED_IN_KNOTS 0x000000010 when use the SHOW_SPEED option, display speed in knots instead in km/h
- * #define OPTION_RAW_NMEA 0x000000100 outputs the parsed nmea string, only valid when EMULATE is not defined!
- * #define OPTION_GET_BUFFERDATA 0x000001000 when you define more than 1 gps widget
- * each widget will get updates and cause some ugly side effects, specially when you display the time
- * by enabling this option, the widget will not read any nmea data from the serial port.
- * KEEP IN MIND that there must be ONE widget which get buffered data (means read data from the port)
- *
- * #define SHOW_NMEA_STATUS 0x010000000 OK:0033/Error:0002/Incomplete:0002
- *
- *
- * Examples:
- * - gps::parse('0x011','0') will display the altitude and speed -> alt:500 spd:43
- * - gps::parse('0x01100','0') will display the course and the numbers of satellites -> dir:NO sat:3
- * - gps::parse('0x01','0x01') will display the speed without prefix -> 50
- * - gps::parse('0x01','0x01') will display the speed in knots without prefix -> 27
- *
- * ENV VARIABLES
- * To finetune plugin_gps you may define some env variables:
- * GPS_PORT gps device, default value is /dev/usb/tts/1
- * GPS_9600 serial port speed, default is 4800 baud, if you define this var speed will be 9600 (export GPS_9600=dummy)
