I developed this UN*X library back in 2005 when I was using the Timex Data Link USB watch to transfer data between my laptop and watch. I do not maintain this library anymore since my watch broke a while ago. There were two projects forked from this library: wxDatalinkUSB (wxWidgets GUI for this library) and libdlusb-0.0.9-mac (a port for Mac OS). This Git repository was imported from the latest version in my local CVS repository for archiving purposes.

libdlusb is a library used to communicate with the Timex Data Link USB watch on various UN*X operating systems. The library can be built with two USB libraries: libusb (OS-independent USB library) and usbhid (USB HID library for *BSD).

The communication protocol was implemented based on "Data Link USB Communication Protocol and Database Design Guide," which is distributed by Timex Corporation.

This software can cause severe damage to your Timex Data Link USB watch. Use at your own risk.

Be prepared to do hard-reset!

1. Create Makefile. The configure script generates Makefile for libusb support by default:

   ./configure --prefix=$HOME
   

2. Build the library and test programs:

   make
   

3. Install programs under $HOME/bin (${prefix}/bin):

   make install
   

4. Edit $HOME/.dlusbrc

Now you have libdlusb.a and several test programs. If you want a shared library, add --enable-shared option to configure (./configure --enable-shared) and run make.

NOTE: Under *BSD, install the libusb port from /usr/ports/devel/libusb and unload the uhid kernel module or disable it from the kernel config.

This applies only to *BSD.

1. As root, you need to add the following lines into the kernel config (/usr/src/sys/i386/conf/MYKERNEL) to support USB and HID:

   device	uhci
   device	ohci
   device	ehci
   device	usb
   device	ugen
   device	uhid
   

2. Recompile the kernel and reboot:

   cd /usr/src
   make kernel KERNCONF=MYKERNEL
   reboot
   

3. Configure libdlusb with usbhid support:

   ./configure --with-usbhid --prefix=$HOME
   

4. Build the library and test programs:

   make
   

5. Install programs under $HOME/bin (${prefix}/bin):

   make install
   

6. Edit $HOME/.dlusbrc

7. Use /dev/uhid0 for the device file. If it doesn't work, you can see which file is linked with the watch by tailing /var/log/message while attaching/detaching the watch (tail -f /var/log/message).

That's it! Add --enable-shared option to configure (./configure --with-usbhid --enable-shared) to build a shared library.

NOTE: When you switch between the two USB libraries, make sure to delete an old library (make clean; rm -f libdlusb.*; ./configure ...).
