Driver documentation for yealink usb-p1k phones
0. Status
~~~~~~~~~
The p1k is a relatively cheap usb 1.1 phone with:
- keyboard full support, yealink.ko / input event API
- LCD full support, yealink.ko / sysfs API
- LED full support, yealink.ko / sysfs API
- dialtone full support, yealink.ko / sysfs API
- ringtone full support, yealink.ko / sysfs API
- audio playback full support, snd_usb_audio.ko / alsa API
- audio record full support, snd_usb_audio.ko / alsa API
For vendor documentation see http://www.yealink.com
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
5. Sound features
~~~~~~~~~~~~~~~~~
Sound is supported by the ALSA driver: snd_usb_audio
One 16-bit channel with sample and playback rates of 8000 Hz is the practical
limit of the device.
Example - recording test:
arecord -v -d 10 -r 8000 -f S16_LE -t wav foobar.wav
Example - playback test:
aplay foobar.wav
6. Credits & Acknowledgments
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
- Olivier Vandorpe, for starting the usbb2k-api project doing much of
the reverse engineering.
- Martin Diehl, for pointing out how to handle USB memory allocation.
- Dmitry Torokhov, for the numerous code reviews and suggestions.

/*
* This supports simple USB network links that don't require any special
* framing or hardware control operations. The protocol used here is a
* strict subset of CDC Ethernet, with three basic differences reflecting
* the goal that almost any hardware should run it:
*
* - Minimal runtime control: one interface, no altsettings, and
* no vendor or class specific control requests. If a device is
* configured, it is allowed to exchange packets with the host.
* Fancier models would mean not working on some hardware.
*
* - Minimal manufacturing control: no IEEE "Organizationally
* Unique ID" required, or an EEPROMs to store one. Each host uses
* one random "locally assigned" Ethernet address instead, which can
* of course be overridden using standard tools like "ifconfig".
* (With 2^46 such addresses, same-net collisions are quite rare.)
*
* - There is no additional framing data for USB. Packets are written
* exactly as in CDC Ethernet, starting with an Ethernet header and
* terminated by a short packet. However, the host will never send a
* zero length packet; some systems can't handle those robustly.
*
* Anything that can transmit and receive USB bulk packets can implement
* this protocol. That includes both smart peripherals and quite a lot
* of "host-to-host" USB cables (which embed two devices back-to-back).
*
* Note that although Linux may use many of those host-to-host links
* with this "cdc_subset" framing, that doesn't mean there may not be a
* better approach. Handling the "other end unplugs/replugs" scenario
* well tends to require chip-specific vendor requests. Also, Windows
* peers at the other end of host-to-host cables may expect their own
* framing to be used rather than this "cdc_subset" model.

* All known Zaurii lie about their standards conformance. At least
* the earliest SA-1100 models lie by saying they support CDC Ethernet.
* Some later models (especially PXA-25x and PXA-27x based ones) lie
* and say they support CDC MDLM (for access to cell phone modems).
*
* There are non-Zaurus products that use these same protocols too.
*
* The annoying thing is that at the same time Sharp was developing
* that annoying standards-breaking software, the Linux community had
* a simple "CDC Subset" working reliably on the same SA-1100 hardware.
* That is, the same functionality but not violating standards.
*
* The CDC Ethernet nonconformance points are troublesome to hosts
* with a true CDC Ethernet implementation:
* - Framing appends a CRC, which the spec says drivers "must not" do;
* - Transfers data in altsetting zero, instead of altsetting 1;
* - All these peripherals use the same ethernet address.
*
* The CDC MDLM nonconformance is less immediately troublesome, since all
* MDLM implementations are quasi-proprietary anyway.
