PT-90 Mobile Computer SDK Programming Manual 2
Overview
The Argox PT-90 Mobile Computer Software Developer Kit (SDK) Programming Manual is
prepared to assist programmers on developing application programs using Argox PT-90 Mobile
Computers under Microsoft® Windows® CE6.0 Operating System. It gives all the details needed
to call functional subroutines controling the devices on the Argox PT-90 Mobile Computer or
access value-added devices on board such as Scanning and Wireless module.
This Programming Manual is organized as two major sections, one for the system related functions
and the other for value-added scanning functions with the following information:
Argox Mobile Computer standard Application Programming Interface (API) Definitions
for system related functions:
Audio
Display
Keypad
Led and Vibrator Indicators
Battery Status
System Settings
Bluetooth
WLAN
Argox Scanning module Application Programming Interface (API) Definitions
API definitions illustrate how to call a given functional subroutine. The API definitions are
structed with information including: prototypes, parameters, return values, examples, and
requirements of each API. The “Requirements” section gives information on whether or not a
device supports a specific API function and the files to be included.
PT-90 Mobile Computer SDK Programming Manual 3
SDK Functions
When using SDK to develop their own application program, the programmer should link DLL file
or LIB file, then, include header file SYSAPIAX.H.
The following two examples are given to show how to use LIB file and DLL file while developing
an application program. We will use Visual Studio 2005 to illustrate.
Example 1: Using LIB file.
First, programmer should include sysapiax.lib in the application project.
#include "Sysapiax.h"
main()
{
. . . . .
SetBacklightPWM(100, 100);
. . . . .
}
Example 2: Using DLL file.
HINSTANCE dllHandle = NULL;
typedef DWORD (_stdcall *pfnSetBacklightPWM)(int nACPowerPercent, int
nBatteryPercent);
pfnSetBacklightPWM m_SetBacklightPWM;
main()
{
dllHandle = LoadLibrary(L"SYSAPIAX.dll");
m_SetBacklightPWM = (pfnSetBacklightPWM) ::GetProcAddress(dllHandle,
_T("SetBacklightPWM"));
m_SetBacklightPWM(0, 0);
FreeLibrary(dllHandle);
}
PT-90 Mobile Computer SDK Programming Manual 4
SYSAPIAX.DLL
In PT-90 SDK, we provide SYSAPIAX.DLL which includes several functions to allow
programmer to control device drivers and system functions. Programmer can use WINCE develop
tool like Visual Studio 2005 to develop application programs. Descriptions of all these functions
