AudioScope.sh Version 0.31.40.

Due to the numerous chocies of Linux installs that are now available I have discovered that some do not have 'xterm' installed by default. This has now become a dependency as Linux Mint 17, 64 bit requires that you install 'xterm' if you need to use it.

Also CygWin did not have semi-automatic calibration of the display polarity.
This is now taken care of using the limitations of 'mintty' used in a default install of CygWin.

More done to the Manual including an ultra-simple detector circuit and usage for the display polarity calibration using a MacBook Pro 13 inch ONLY, (in my case circa August 2012). This may or may not work for other platforms but it is NOT intanded for those.
This is in an Appendix at the end of the Manual.

Very soon this code will be able to be used as a fun, calibrated, AC coupled only tool for anyone to use...

As it stands if you have already built the circuits including the Vertical amp then it is a fun, uncalibrated, usable audio OSCILLOGRAPH. ;o)

Calibrating without the kit is ALWAYS the difficult part.

Stas so far:-

PALMAX(4x)																PALMAX(4x)

NAME

       palmax - Palmax (TR88L803) touchscreen driver

SYNOPSIS

       Section "InputDevice"
	 Identifier "idevname"
	 Driver "palmax"
	 Option "Device"   "devpath"
	 ...
       EndSection

DESCRIPTION

       palmax is an XFree86 input driver for the Palmax PD1000/PD1100

       The  palmax  driver  functions  as a pointer input device, and is normally used as the X server's core pointer. It supports positioning and
       mouse buttons using the touchscreen display and lid buttons on the Palmax machines.

SUPPORTED HARDWARE

       Palmax PD1000, Palmax PD1100. In theory also any other system using a TR88L803 wired to a serial port.

CONFIGURATION DETAILS

       Please refer to XF86Config(5x) 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.

       The following driver options are supported

       Option "MinX" "integer"
	      Set the left hand X value from the touchscreen, for calibration.

       Option "MaxX" "integer"
	      Set the right hand X value from the touchscreen, for calibration.

       Option "MinY" "integer"
	      Set the top Y value from the touchscreen, for calibration.

       Option "MaxY" "integer"
	      Set the bottom Y value from the touchscreen, for calibration.

       Option "Screen" "integer"
	      The screen to attach to the touchscreen when running with multiple screens.  The default is screen 0.

       Option "Device" "string"
	      The serial port that is attached to the touchscreen interface. On the Palmax PD1000 and PD1100 this is ttyS0.

       Option "DeviceName" "string"
	      Set the X11 device name for the touchscreen. This defaults to TOUCHSCREEN.

       Option "PortraitMode" "string"
	      Set the display orientation. The default is "landscape" but you can rotate the screen clockwise ("portrait") or anticlockwise ("por-
	      traitCCW").

       Option "SwapXY" "boolean"
	      Swap the X and Y values on the display. The default is false.

       Option "TapButton" "boolean"
	      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.

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.

       Support for a double-tap menu button option would be nice.

       The smoothing algorithm would benefit from real mathematics.

       XFree86 needs a nice calibration tool.
