+yealink - Linux driver for usb-p1k phones
+
+0. Status
+~~~~~~~~~
+
+The p1k is a relatively cheap usb 1.1 phone with:
+ - keyboard full support
+ - LCD full support
+ - LED full support
+ - dialtone full support
+ - ringtone full support
+ - audio playback via generic usb audio diver
+ - audio record via generic usb audio diver
+
+
+1. Compilation (stand alone version)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Currently only kernel 2.6.x.y versions are supported.
+In order to build the yealink.ko module do:
+
+ make
+
+If you encounter problems please check if in the MAKE_OPTS variable in
+the Makefile is pointing to the location where your kernel sources
+are located, default /usr/src/linux.
+
+
+
+2. keyboard features
+~~~~~~~~~~~~~~~~~~~~
+The current mapping in the kernel is provided by the map_p1k_to_key
+function:
+
+ Physical USB-P1K button layout input events
+
+
+ up up
+ IN OUT left, right
+ down down
+
+ pickup C hangup enter, backspace, escape
+ 1 2 3 1, 2, 3
+ 4 5 6 4, 5, 6,
+ 7 8 9 7, 8, 9,
+ * 0 # *, 0, #,
+
+ The "up" and "down" keys, are symbolised by arrows on the button.
+ The "pickup" and "hangup" keys are symbolised by a green and red phone
+ on the button.
+
+
+3. LCD features
+~~~~~~~~~~~~~~~
+The LCD is divided and organised as a 3 line display:
+
+ |[] [][] [][] [][] in |[][]
+ |[] M [][] D [][] : [][] out |[][]
+ store
+
+ NEW REP SU MO TU WE TH FR SA
+
+ [] [] [] [] [] [] [] [] [] [] [] []
+ [] [] [] [] [] [] [] [] [] [] [] []
+
+
+Line 1 Format (see below) : 18.e8.M8.88...188
+ Icon names : M D : IN OUT STORE
+Line 2 Format : .........
+ Icon name : NEW REP SU MO TU WE TH FR SA
+Line 3 Format : 888888888888
+
+
+Format description:
+ From a user space perspective the world is seperated in "digits" and "icons".
+ A digit can have a character set, an icon can only be ON or OFF.
+
+ Format specifier
+ '8' : Generic 7 segment digit with individual addressable segments
+
+ Reduced capabillity 7 segm digit, when segments are hard wired together.
+ '1' : 2 segments digit only able to produce a 1.
+ 'e' : Most significant day of the month digit,
+ able to produce at least 1 2 3.
+ 'M' : Most significant minute digit,
+ able to produce at least 0 1 2 3 4 5.
+
+ Icons or pictograms:
+ '.' : For example like AM, PM, SU, a 'dot' .. or other single segment
+ elements.
+
+
+4. Driver usage
+~~~~~~~~~~~~~~~
+For userland the following interfaces are available using the sysfs interface:
+ /sys/.../
+ line1 Read/Write, lcd line1
+ line2 Read/Write, lcd line2
+ line3 Read/Write, lcd line3
+
+ get_icons Read, returns a set of available icons.
+ hide_icon Write, hide the element by writing the icon name.
+ show_icon Write, display the element by writing the icon name.
+
+ map_seg7 Read/Write, the 7 segments char set, common for all
+ yealink phones. (see map_to_7segment.h)
+
+ ringtone Write, upload binary representation of a ringtone,
+ see yealink.c. status EXPERIMENTAL due to potential
+ races between async. and sync usb calls.
+
+
+4.1 lineX
+~~~~~~~~~
+Reading /sys/../lineX will return the format string with its current value:
+
+ Example:
+ cat ./line3
+ 888888888888
+ Linux Rocks!
+
+Writing to /sys/../lineX will set the coresponding LCD line.
+ - Excess characters are ignored.
+ - If less characters are written than allowed, the remaining digits are
+ unchanged.
+ - The tab '\t'and '\n' char does not overwrite the original content.
+ - Writing a space to an icon will always hide its content.
+
+ Example:
+ date +"%m.%e.%k:%M" | sed 's/^0/ /' > ./line1
+
+ Will update the LCD with the current date & time.
+
+
+4.2 get_icons
+~~~~~~~~~~~~~
+Reading will return all available icon names and its current settings:
+
+ cat ./get_icons
+ on M
+ on D
+ on :
+ IN
+ OUT
+ STORE
+ NEW
+ REP
+ SU
+ MO
+ TU
+ WE
+ TH
+ FR
+ SA
+ LED
+ DIALTONE
+ RINGTONE
+
+
+4.3 show/hide icons
+~~~~~~~~~~~~~~~~~~~
+Writing to these files will update the state of the icon.
+Only one icon at a time can be updated.
+
+If an icon is also on a ./lineX the corresponding value is
+updated with the first letter of the icon.
+
+ Example - light up the store icon:
+ echo -n "STORE" > ./show_icon
+
+ cat ./line1
+ 18.e8.M8.88...188
+ S
+
+ Example - sound the ringtone for 10 seconds:
+ echo -n RINGTONE > /sys/..../show_icon
+ sleep 10
+ echo -n RINGTONE > /sys/..../hide_icon
