Embodiment
Shown in Figure 1, be the structural representation of microcontroller programming system of the present invention.The programing system of this microcontroller comprises: server end 1, client 2 and programmable device 3.Server end 1 and client 2 is connected and can communicates for long-range, and client 2 is connected for this locality with programmable device 3 and also can communicates.In one embodiment, this server end 1 can be a PC with client 2, realizes long-range connection by the internet; Realize local the connection by USB interface between client 2 and the programmable device 3.But the present invention does not limit this, can adopt other connection means well known to those skilled in the art yet, for example, realizes that by LAN (Local Area Network), wireless network etc. server end 1 is connected with the long-range of client 2; Perhaps for example serial port, parallel port etc. realize that client 2 is connected with this locality between the programmable device 3 by other interfaces.In addition, programmable device 3 is connected with microcontroller 4 and carries out programming.
An embodiment of programmed method of the present invention as shown in Figure 2, before microcontroller 4 programmings, server end 1 will need programming to carry out data encryption and add to allow the inferior numerical value N (N=100 for example represents that promptly this programmable device at most can 100 microcontrollers of programming) of programming to the HEX code file in the target device (being microcontroller); This encryption back data file is transmitted by client 2 according to predetermined agreement and is saved in the programmable device 3.
In the programming process, programmable device 3 is written to the HEX code file after the deciphering reduction in the microcontroller 4 earlier with the deciphering of HEX code file.After the programming success once, will allow the inferior numerical value N of programming to deduct 1, and the value N after will upgrading notes, whether in order to allow next time programming provides basis for estimation.
The module diagram of programmable device 3 of the present invention as shown in Figure 3, it comprises control module 31, the storer 32, programming interface 33 and the transmission interface 34 that link to each other with this control module 31 respectively.Programmable device 3 is connected with microcontroller 4 by programming interface 33, links to each other with PC as client 2 by transmission interface 34.The encryption HEX code file of downloading by client 2 is kept in the storer 32.Wherein, described storer 32 can be the Flash storer, and programming interface 33 can be 16 common core interfaces, and transmission interface 34 can be USB interface.
In another preferred embodiment, described record judge module 31 can also be controlled the operation of deciphering module 311 and programming module 312 by time parameter.That is, also can add default programming term of validity T in the above-mentioned encrypted data code file.For example, T=30 days, expression finished receiving from data file and allows to carry out programming in 30 days, surpassed 30 days, and then the data code file lost efficacy, even if above-mentioned permission programming limits value N does not allow programming greater than zero yet.
The process flow diagram of this embodiment as shown in Figure 4, its most of step is identical with embodiment shown in Figure 2, difference is, allows also to have added term of validity T the programming number of times limits value N except adding during encrypt file; After judging the step that allows programming time numerical value, judge the step of term of validity T again.That is, allow the programming times N greater than zero prerequisite under, current time and term of validity T are compared, when not exceeding term of validity T, can carry out above-mentioned programming and operate; When exceeding term of validity T, then do not allow to carry out programming.Can further prevent bootlegging like this.
In another embodiment, whether above-mentioned judgement allows the step of programming time numerical value in other words, can judge whether to exceed the term of validity earlier after the step of judging term of validity T, judge to allow the programming times N greater than zero again.
In order to realize the time control function in embodiment illustrated in fig. 4, also need comprise the clock (not shown) in the control module 31 shown in Figure 3, be used for writing time, whether exceed term of validity T so that judge the current time.
As other embodiment of the present invention, above-mentioned permission programming number of times limits value N and term of validity T can set in advance in programmable device 3, and needn't be transferred to programmable device 3 together by data file encryption.
