Embodiment
The invention provides the method and system realizing Key code robotization burning based on MSComm control, for making object of the present invention, technical scheme and effect clearly, clearly, the present invention is described in more detail below.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Refer to Fig. 1, Fig. 1 is a kind of process flow diagram realizing the method preferred embodiment of Key code robotization burning based on MSComm control of the present invention, as shown in the figure, comprises step:
S101, FCT automated test tool carries out functional test to mainboard, in test by rear, sends burning notification message by a MSComm serial port module to Key code replication tool;
S102, Key code replication tool carries out the burning of Key code to mainboard after receiving burning notification message by the 2nd MSComm serial port module, and by the 2nd MSComm serial port module, burning result is sent to FCT automated test tool.
FCT automated test tool and Key code replication tool are separate originally, realize the integrated of the two, need to set up a kind of contact therebetween and namely intercom mutually, in order to realize the intercommunication mutually between two instruments, the present invention adopts point-to-point serial communication mode, and serial communication is convenient and easy.Concrete, the communication that MSComm control (a MSComm serial port module and the 2nd MSComm serial port module) realizes between FCT automated test tool and Key code replication tool is utilized in the present invention, this control has abundant with the closely-related attribute of serial communication and event, provide the communications command interface of series of standards, utilize control can create signal procedure that is full duplex, event driven, highly effective.
As shown in Figure 2, the communication steps of a MSComm serial port module or the 2nd MSComm serial port module comprises:
S201, initialization the one MSComm serial port module or the 2nd MSComm serial port module;
The initialization of this step has been mainly used in arranging the parameter initialization of serial ports, comprises the port of use, communication baud rate, parity checking, data bit and position of rest.Specifically can realize Initialize installation in based on the program of dialog box.
S202, setting open serial ports;
After initialization completes, need specifically to arrange serial ports parameters, just can open the serial ports setting parameter afterwards.Attributions selection mode can be adopted to arranging of serial ports.The underlying attribute parameter of the MsComm that the present invention uses is: sending/receiving buffer length, serial data obtain manner (text/scale-of-two) etc.
S203, process Serial Port Event;
Serial Port Event process comprises reception/transmission serial data and the process to garble.MsComm control provides two kinds of event handling modes: one is inquiry mode, judges event or mistake by the attribute of the CommEvent checking control; Another kind is event driven manner, and when serial ports generation event or mistake can produce OnComm event, event driven manner reliability is high, and response in time.Key code replication tool is the order of being held by FCT, performs corresponding process, and returns results.
S204, use serial ports after, close serial ports, to discharge serial port resource.
Key code replication tool, after completing the burning of a Key code, need to close current serial ports, otherwise burning next time can not obtain serial port resource.
In the present invention, be exactly increase by a MsComm serial port module at Key code replication tool, intercom mutually with the second serial module of FCT automated test tool, realize the robotization burning of Key code replication tool.Due to the test platform that FCT automated test tool is complete set, by a host computer control two mainboard testing jigs, so Key code replication tool can run on any main frame, Key code replication tool is incorporated into FCT automated test tool by the present invention, solve and produce the problem that after-stage mainboard detects poor efficiency, improve mainboard robotization integrated level
Specifically, the step sending burning notification message by a MSComm serial port module to Key code replication tool specifically comprises:
Order is encapsulated;
Then order is sent;
Carry out time-out to process of transmitting again judge and verify order;
Finally return transmission result.
Such as an instantiation is, as shown in Figure 3:

S302, transmission order;
S303, judge whether time-out, time-out time is 30ms, if then enter step S306, otherwise enters step S304;
S304, judge whether that data return; If words then enter step S305, otherwise return step S303;
S305, judge whether that verification is correct, if words then enter step S307, otherwise enter step S306;
S306, judge that whether transmission times is more than 3 times, if then enter step S307, otherwise returns step S302;
S307, transmission result;
S308, end.
Specifically, the step that Key code replication tool receives burning notification message by the 2nd MSComm serial port module specifically comprises:
Carry out time-out to judge;
Receive order;
Order is verified; ;
Transferring command;
Return state code.
A concrete example is as follows, as shown in Figure 4:
S401, judge that whether receiving course is overtime, such as time-out time is 10ms, if then enter S408, otherwise enters step S402;
S402, reception data;
S403, judge that whether data complete, if words then enter step S404, otherwise return step S401;
S404, judge whether that verification is correct, if words then enter step S405, otherwise proceed to step S407;
S405, transmission data;
S406, judge whether to need return data, if then enter step S407, otherwise return and continue to judge;
S407, return state code;
S408, end.
Said process is provided with transmission and receive time-out clock, improves the accuracy rate transmitted and receive data, and in order to ensure the validity that transmits and receive data, is provided with check bit for checking.
To intercom mutually with Key code replication tool to make FCT automated test tool and carry out action accurately, except utilizing serial ports and communicating, also can use the message that both can identify, can corresponding action be carried out.Because serial ports is that both sides send and the process received, therefore can in advance according to project actual demand, self-defined setting is carried out to the communication protocol of a MSComm serial port module and the 2nd MSComm serial port module, specifically comprises and bag preamble code, packet length, command code, data and check code are arranged.Protocol rule can be arranged shown according to the form below 1:
