2. 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 hardware and mechanical parts. Embedded system contains processing cores that are either microcontrollers or digital signal processors (DSP).

9. SDK
What is SDK?
SDK is abbreviation of Software Development Kit,which is also typical a set of software development tool for:
Creating Applications for Software Package
Software Framework
Operating System/Video Game Console

Sample Code Technical Notes

11. 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

12. DLL(Dynamic-link library) containing any combination of code,data and resources is the concept of 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.

15. API Example CKT_GetDeviceInfo
[Funciton] retrieve device’s system information
[Prototype] CKT_RESULT WINAPI CKT_GetDeviceInfo (int sno,LPDEVICEINFO devinfo)
[Parameter] sno :Device ID,scope:1 ——
devinfo:Structure pointing receiving system information
[Return] success return1(TRUE)
fail return 0(FALSE)

16. 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

17. 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( , &devinfo)) {
printf("(CKT_GetDeviceInfo success.\n"); }
[Note]
The returned structure members Parameter, DefaultAuth is no sense, just keeping compatible with OA200.
