* you need a compiled libnmeap to compile this plugin. - * - * History: - * v0.1 -initial release - * v0.2 -fix include files, include and (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 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) - */ - - -/* define the include files you need */ -#include "config.h" - -#include -#include -#include -#include -#include -#include //used for serial port flags -#include -
