It supports positioning and mouse buttons using +the touchscreen display and lid buttons on the Palmax machines. +.SH SUPPORTED HARDWARE +Palmax PD1000, Palmax PD1100. In theory also any other system using a +TR88L803 wired to a serial port. +.SH CONFIGURATION DETAILS +Please refer to XF86Config(__filemansuffix__) for general configuration +details and for options that can be used with all input drivers. This +section only covers configuration details specific to this driver. +.PP +The following driver +.B options +are supported +.TP +.BI "Option \*qMinX\*q \*q" integer \*q +Set the left hand X value from the touchscreen, for calibration. +.TP +.BI "Option \*qMaxX\*q \*q" integer \*q +Set the right hand X value from the touchscreen, for calibration. +.TP +.BI "Option \*qMinY\*q \*q" integer \*q +Set the top Y value from the touchscreen, for calibration. +.TP +.BI "Option \*qMaxY\*q \*q" integer \*q +Set the bottom Y value from the touchscreen, for calibration. +.TP +.BI "Option \*qScreen\*q \*q" integer \*q +The screen to attach to the touchscreen when running with multiple screens. +The default is screen 0. +.TP +.BI "Option \*qDevice\*q \*q" string \*q +The serial port that is attached to the touchscreen interface. On the Palmax +PD1000 and PD1100 this is ttyS0. +.TP +.BI "Option \*qDeviceName\*q \*q" string \*q +Set the X11 device name for the touchscreen. This defaults to TOUCHSCREEN. +.TP +.BI "Option \*qPortraitMode\*q \*q" string \*q +Set the display orientation. The default is "landscape" but you can rotate +the screen clockwise ("portrait") or anticlockwise ("portraitCCW"). +.TP +.BI "Option \*qSwapXY\*q \*q" boolean \*q +Swap the X and Y values on the display. The default is false. +.TP +.BI "Option \*qTapButton\*q \*q" boolean \*q +Set the touchscreen tap to act as mouse button 1. This allows single handed +operation except when using the menu buttons. The default is false. +.SH "BUGS" +The driver has been tested on the Palmax systems, the defaults reflect the +Palmax hardware and should work out of the box. No testing has been done on +other systems using the same digitizer. +.PP +Support for a double-tap menu button option would be nice. +.PP +The smoothing algorithm would benefit from real mathematics. +.PP +XFree86 needs a nice calibration tool. +.PP +.SH "SEE ALSO" +XFree86(1), XF86Config(__filemansuffix__), xf86config(1), Xserver(1), X(__miscmansuffix__). +.SH AUTHORS +Authors include... + Alan Cox diff --git a/src/xf86Palmax.c b/src/xf86Palmax.c new file mode 100644 index 0000000..b7728d4 --- /dev/null +++ b/src/xf86Palmax.c @@ -0,0 +1,822 @@ +/* $XFree86: xc/programs/Xserver/hw/xfree86/input/palmax/xf86Palmax.c,v 1.1 2002/11/22 03:40:22 dawes Exp $ */ + +#include "misc.h" +#include "xf86.h" +#include "xf86_OSproc.h" +#include "xf86Xinput.h" +#include "exevents.h" +#include "os.h" + +#ifdef XFree86LOADER +#include "xf86Module.h" +#endif + +/* + *************************************************************************** + * + * Default constants. + * + *************************************************************************** + */ + +#define DEFAULT_MAX_X 63104 +#define DEFAULT_MIN_X 8786 +#define DEFAULT_MAX_Y 61592 +#define DEFAULT_MIN_Y 7608 + +#define XI_STYLUS "TOUCHSCREEH" /* X device name for the stylus device */ + + +/* + *************************************************************************** + * + * Protocol constants. + * + *************************************************************************** + */ + +#define PMX_REPORT_SIZE 3 /* Size of a report packet. */ +#define PMX_BUFFER_SIZE 256 /* Size of input buffer. */ +#define PMX_PACKET_SIZE 5 /* Maximum size of a command/reply *including* */ + +static const char *reqSymbols[] = { + "AddEnabledDevice", + "ErrorF", + "InitButtonClassDeviceStruct", + "InitProximityClassDeviceStruct", + "InitValuatorAxisStruct", + "InitValuatorClassDeviceStruct", + "InitPtrFeedbackClassDeviceStruct", + "RemoveEnabledDevice", + "Xcalloc", + "Xfree", + "XisbBlockDuration", + "XisbFree", + "XisbNew", + "XisbRead", + "XisbTrace", + "screenInfo", + "xf86AddInputDriver", + "xf86AllocateInput", + "xf86CloseSerial", + "xf86CollectInputOptions", + "xf86ErrorFVerb", + "xf86FindOptionValue", + "xf86GetMotionEvents", + "xf86GetVerbosity", + "xf86MotionHistoryAllocate", + "xf86NameCmp", + "xf86OpenSerial", + "xf86OptionListCreate", + "xf86OptionListMerge", + "xf86OptionListReport", + "xf86PostButtonEvent", + "xf86PostMotionEvent", + "xf86PostProximityEvent", + "xf86ProcessCommonOptions", + "xf86ScaleAxis", + "xf86SetIntOption", + "xf86SetStrOption", + "xf86XInputSetScreen", + "xf86XInputSetSendCoreEvents", + NULL +}; + + /* the leading and trailing bytes. */ + +/* + *************************************************************************** + * + * Device private records. + * + *************************************************************************** + */ + +typedef struct _PMXPrivateRec { + char *input_dev; /* The touchscreen input tty */ + OsTimerPtr uptimer; /* Timeout on stream */ + OsTimerPtr polltimer; /* Button poll timer */ + int min_x; /* Minimum x reported by calibration */ + int max_x; /* Maximum x */ + int min_y; /* Minimum y reported by calibration */ + int max_y; /* Maximum y */ + int cur_x; /* Current x */ + int cur_y; /* Current y */ + int button1; /* True if finger button 1 is down */ + int button2; /* True if finger button 2 is down */ + int button3; /* 1 if button3 down, 2 on wait for up */ + int screen_no; /* Screen associated with the device */ + int screen_width; /* Width of the associated X screen */ + int screen_height; /* Height of the screen */ + Bool inited; /* The controller has already been configured ? */ + char state; /* Current state of report flags. */ + int num_old_bytes; /* Number of bytes left in receive buffer. */ + LocalDevicePtr stylus; /* Stylus device ptr associated with the hw. */ + int swap_axes; /* Swap X an Y axes if != 0 */ + int tap_button; /* Tapping is button 0 */ + unsigned char rec_buf[PMX_BUFFER_SIZE]; /* Receive buffer. */ +} PMXPrivateRec, *PMXPrivatePtr; + + +/* + *************************************************************************** + * + * xf86PmxConvert -- + * Convert extended valuators to x and y suitable for core motion + * events.
