Appendix A
Programming Watchdog Timer
Appendix A: Programming Watchdog Timer
A watchdog timer is a piece of hardware that can be
used to automatically detect system anomalies and reset
the processor in case there are any problems. Generally
speaking, a watchdog timer is based on a counter that
counts down from an initial value to zero. The software
selects the counter’s initial value and periodically restarts
it. Should the counter reach zero before the software
restarts it, the software is presumed to be malfunctioning
and the processor’s reset signal is asserted. Thus, the
processor will be restarted as if a human operator had
cycled the power.
For sample watchdog code, see Watch dog and DIO folder
in the Driver and Manual CD
Click the Setup program.1.
The welcome screen appears. Click Next to proceed.2.
Driver Installation
Before you could access or control the operation of the
watchdog and Digital I/O functions, install the the L_IO
driver which is the library and driver needed for Lanner
General Purpose Input/Output interface or functions.
To install the L_IO driver:
Restart the computer, and then log on with 1.
Administrator privilege.
Insert the Drivers and User’s Manual CD to the USB-2.
optical drive.
Browse the contents of the support CD to locate the 3.
file LannerIO v101.rar under the \WD_DIO\ folder and
unzip the file.
Click the Setup program in the unzipped folder.4.
The installation process proceeds. Click Close when the 3.
process completes.

Digital Input/Output Control
Appendix B: Digital Input/Output Control on the GPIO port
The Digitanl I/O on the panel is designed to provide the
input and output operations for the system. For sample
DIO code, see Watch dog and DIO in the Driver and Manual
CD.
Driver Installation
Before you could access or control the operation of the
watchdog and Digital I/O functions, install the the L_IO
driver which is the library and driver needed for Lanner
General Purpose Input/Output interface or functions.
To install the L_IO driver:
Restart the computer, and then log on with 1.
Administrator privilege.
Insert the Drivers and User’s Manual CD to the USB-2.
optical drive.
Click the Setup program.1.
The welcome screen appears. Click Next to proceed.2.
Browse the contents of the support CD to locate the 3.
file LIO.rar under the \Watch dog and DIO\LIO folder
and unzip the file.
From the control panel, click the ADD Hardware 4.
program
The installation process proceeds. Click Close when the 3.
process completes.
Embedded and Industrial Computing
21
Appendix B
Digital Input/Output Control
To verify the GPIO driver installation, do the following
steps:
Right-click on the My Computer icon, and then select 1.
Properties form the menu.
Click the Hardware tab, then click the Device Manager 2.
button.
Select 3. View from the menu and select show hidden
devices .
The Lanner common GPIO driver should be listed 4.
under the Non-Plug and Play Drivers. If not, click the
San for hardware changes button from the tool bar.
Executing the Sample Program:
To test the sample program, execute the F81865_test with
the appropriate parameters.
DIO:
Usage:
F81865_test DIO_In port_number (reads Digital input
port 0, 1, 2 or 3)
F81865_test DIO_Out port_number value (writes
Digital output port 0, 1, 2 or 3; For port description, refer
to Jumper Settings on Chapter3 Board Layout)
You can also write your own program by modifying the
source code F81865_Test.cpp.. The index address is 2EH.
