Embedded System

What is Embedded System?

An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system. It is embedded in hardware and mechanical parts.

Embedded system contains processing cores that are either microcontrollers or digital signal processors (DSP).

API specifies a set of functions or routines that accomplish a specific task or allow to interact with a specific software component. For example:

#include <math.h>

double sqrt(double X) / float sqrtf(float X); SYNOPSIS

sqrt computes the positive square root of the argument. ... DESCRIPTION

on success, the square root is returned. If X is real and positive...RETURNS

DLL (Dynamic-link library) containing any combination of code, data and resources is the concept of a shared library in the Win OS. These libraries have file extensions such as DLL,OCX, or DRV.

DLL provides a mechanism for shared code and data, allowing a developer to share code or upgrade data without re-compiling the interlinkage of applications.

CKT_GetDeviceInfo

[Funciton] retrieve device’s system information

[Prototype] CKT_RESULT WINAPI CKT_GetDeviceInfo (int sno,LPDEVICEINFO devinfo)

[Parameter] sno :Device ID,scope:1 —— 99999999

devinfo:Structure pointing receiving system information

[Return] success return1(TRUE)

fail return 0(FALSE)

API Example

• typedef struct CKT_DeviceInfo• {• int ID; // Device serial number• int MajorVersion; // Device firmware version• int MinorVersion; // Device firmware version• int DoorLockDelay; // Lock control delay• int SpeakerVolume; // Speaker volume• int Parameter; //• int DefaultAuth; //• int Capacity; // Capacity for the staffer information• int RealTimeAllow;//Allow to transfer data real-time.• int RingAllow;//Allow to make ringing• int LockDelayTime;//Lock delay time• int FixWGHead;//Fixed wiegand area code

• int WGOption;//wiegand option• int AutoUpdateAllow;//Allow to update the fingerprint template intelligently• int KQRepeatTime;//Options for the repeated clocking• char[8] AdminPassword; // Commuinication password• } DEVICEINFO, *LPDEVICEINFO;

[Sample]• DEVICEINFO devinfo;• if (CKT_GetDeviceInfo(12345678, &devinfo))• {• printf("(CKT_GetDeviceInfo success.\n");• }

[Note]

The returned structure members Parameter, DefaultAuth is no sense, just keeping compatible with OA200.
