In the GPIO APIs, we use the signal names ‘GPIO0’, ‘GPIO1’…etc. to identify the GPIO ports.
LAN Bypass Subsystem
Overview
Two pairs of LAN ports on AR-B5800 implement the bypass function. Users can invoke the
LAN Bypass APIs to control the bypass states of the LAN ports and set up the LAN Bypass
Watchdog timer ( this watchdog timer is different from the system watchdog timer mentioned in the
previous paragraph ).
AR-B5800 Library (Window
platform only)
The released code for Windows platform includes a folder called ‘AR-B5800’. In this folder,
there are header files and source codes of all the APIs of LCM module, GPIO, Watchdog, and LAN
Bypass functions. The source codes in this folder generate the API library ‘AR-B5800.lib’ and
‘AR-B5800.dll’. Users who want to invoke the APIs can include the ‘AR-B5800.h’ in their
application source code and compile their application with the library ‘AR-B5800.lib’ or
‘AR-B5800.dll’.
Besides AR-B5800 libraries, there are WinIo32.sys, WinIo32.lib, and WinIo32.dll in this
directory. These files are indispensable for LAN Bypass application, GPIO and Watchdog
application. Please put these three files with LAN Bypass application, GPIO and Watchdog
application in the same folder. The APIs invoke WinIo32.lib, WinIo32.dll, and WinIo32.sys
implicitly.
