The firmware loading method of following explanation electronic installation of the present invention.Refer to Fig. 8, it is that the firmware loading method of electronic installation of the present invention is in the method flow diagram of a preferred embodiment.The firmware loading method of electronic installation comprises:
Step P1: the identification pin 514 that a high level voltage gives General serial bus socket 51 is provided, in order to open the first on-off element 551 and second switch element 552, and then make conducting between the first bus data transfer pin 512 and the first chip data transmission pin 521, and make conducting between the second bus data transfer pin 513 and the second chip data transmission pin 522; And
Step P2: make firmware data transmit entered function chip 52 after sequentially via the first bus data transfer pin 512 and the first chip data transmission pin 521.
In detail, refer to Fig. 9, firmware to be loaded into the schematic diagram of the functional chip of electronic installation by it for method shown in application drawing 8.External jig plate 8 (even an electronic installation) deposits the firmware data needed for electronic installation 5, and there is General serial bus socket 81 and a shift knob 82, when the research staff of electronic installation 5 or user for firmware is inputed to functional chip 52 or for upgrading the firmware in functional chip 52 time, first by the plug 71,72 at universal serial bus 7 two ends is plugged in the General serial bus socket 51 of electronic installation 5 and the General serial bus socket 81 of external jig plate 8 respectively, be connected with external jig plate 8 to make electronic installation 5.
Moreover, research staff or user make external jig plate 8 provide high level voltage by trigger switch button 82, make high level voltage via the identification pin 514 transferring to General serial bus socket 51 after universal serial bus 7, thus, first on-off element 551 and second switch element 552 just can be triggered unlatching, and then make conducting between the first bus data transfer pin 512 and the first chip data transmission pin 521, and make conducting between the second bus data transfer pin 513 and the second chip data transmission pin 522, its step P1 as described in Figure 8, and due to switched between the first bus data transfer pin 512 and the first chip data transmission pin 521, the firmware data S3 that deposits of external jig plate 8 just can after sequentially via universal serial bus 7, first bus data transfer pin 512 and the first chip data transmission pin 521 transmission entered function chip 52, its step P2 as described in Figure 8.
What remark additionally is, because electronic installation 5 shown in Fig. 9 is in the process being loaded into firmware, second bus data transfer pin 513 and the second chip data transmission pin 522 are not all utilized, therefore the step P1 of method shown in Fig. 8 can simplified design be: when the identification pin 514 of General serial bus socket 51 is provided a high level voltage, the first on-off element 551 is only had to be unlocked; Again furthermore, electronic installation 5 shown in Fig. 4 also can simplified design for not comprise second switch element 552, and the second bus data transfer pin 513 is only in floating or ground state, and is not connected with the second chip data transmission pin 522.
Refer to Figure 10, it is that the firmware loading method of electronic installation of the present invention is in the method flow diagram of another preferred embodiment.Method shown in Figure 10 is roughly similar to person described in Fig. 8, is namely no longer repeated at this, and difference is, method shown in Figure 10 also comprises a step P between step P1 and step P2:
The inquiry message S4 that external jig plate 8 is exported is sequentially via transmission entered function chip 52 after universal serial bus 7, first bus data transfer pin 512 and the first chip data transmission pin 521; Wherein, if functional chip 52 has a return information S5 of output and makes this return information S5 in time sequentially transmitting back external jig plate afterwards via the second chip data transmission pin 522, second bus data transfer pin 513 and universal serial bus line 7 after receiving this inquiry message S4, just perform step P2.
According to above explanation, as long as research staff or user are connected by the external jig plate 8 universal serial bus 7 being made electronic installation 5 and deposit firmware, just firmware can be inputed to the functional chip 52 of electronic installation 5 or the firmware in functional chip 52 is upgraded, solving research staff or user in prior art must, first by the complicated procedures of wire bonds between functional chip and external jig plate etc., be also an invention having industry applications in fact.
What will illustrate in addition is, from the explanation of Fig. 2 and Fig. 3 in prior art, the General serial bus socket 11B of electronic installation 1C only for the interface being used as charging, therefore General serial bus socket 11B the first bus data transfer pin 112, second bus data transfer pin 113 and identify pin 114 former be three pins not having function; Be with, the present invention is designed the first bus data transfer pin 512, second bus data transfer pin 513 of electronic installation 5, the circuit connecting relation between identification pin 514 and functional chip 52, and make the General serial bus socket 51 of electronic installation 5 not only can be used to as charging interface, also can be used as carry out firmware be loaded into upgrade interface.
Moreover, from the explanation of Fig. 1 in prior art, when electronic installation 1A is connected to computer system 2 by universal serial bus line 3, computer system 2 can carry out communication program between elder generation and functional chip 12A, with so the specification of identification electronic installation 1A, but because the first bus data transfer pin 512 of the General serial bus socket 51 of electronic installation 5 of the present invention is not the first device identification pin being connected to functional chip 52, and the second bus data transfer pin 513 of General serial bus socket 51 is not the second device identification pin being connected to functional chip 52, or even the functional chip 52 of electronic installation 5 of the present invention does not have first device identification pin and the second device identification pin, therefore when if electronic installation 5 is connected to computer system, first bus data transfer pin 512 of General serial bus socket 51 and the second bus data transfer pin 513 be not in floating or in ground state, then can there is the situation that computer system erroneous judgement electronic installation 5 is " device that can not identify ", and then cause computer system cannot charge to electronic installation 5.
Be with, in order to avoid the generation of said circumstances, the present invention utilizes and identifies that the height of voltage level of pin 514 to be used as judging between the first bus data transfer pin 512 and the first chip data transmission pin 521 of functional chip 52 foundation of whether conducting, and as the foundation of whether conducting between the second bus data transfer pin 513 and the second chip data transmission pin 522 of functional chip 52; That is, when electronic installation 5 is connected to computer system by universal serial bus 7 and charges, because the voltage of the now identification pin 514 of universal serial bus is low level voltage, therefore the first bus data transfer pin 512 of General serial bus socket 51 and the second bus data transfer pin 513 are floating or are ground state, therefore computer system can be charged to electronic installation 5 smoothly; And when electronic installation 5 is connected to external jig plate 8 by universal serial bus 7 and carries out loading firmware action, due to the identification pin 514 that external jig plate 8 can provide high level voltage to give universal serial bus, therefore the first bus data transfer pin 512 can be switched on the first chip data transmission pin 521 of functional chip 52, and the second bus data transfer pin 513 can be switched on the second chip data transmission pin 522 of functional chip 52, the firmware data therefore in external jig plate 8 can transmit entered function chip 52.
The foregoing is only preferred embodiment of the present invention, and be not used to limit claim of the present invention, under therefore all other does not depart from disclosed spirit, the equivalence that completes changes or modifies, and all should be contained in the claim of this case.
