Below with reference to accompanying drawings embodiments of the invention are described in detail.
In Fig. 2, control system 1 comprises a model recognizer 11 and a controller 12.Each hardware 2 in the series is exported a different ID value according to each model.Model recognizer 11 receives from the ID value of hardware unit 2 outputs, discerns the model that this hardware unit 2 has then.Controller 12 specifies a specific model function to give a function pointer, each model of control hardware device then according to the model that identifies.
Fig. 3 a and 3b show the structure of hardware unit 2 of simplification of the method for the hardware unit that is used to illustrate the control embodiment of the invention.Model C and model D have the port 3 of ID value that is used to export its model separately.When the voltage of port 3 was Vcc, when just the voltage of port 3 was corresponding to a system voltage, model recognizer 11 these hardware units of identification were model C, and when port 3 was grounded, model recognizer 11 these hardware units of identification were model D.Remaining hardware unit is identical on structure and the course of work, but they have the different port of the signal that is used for the output drive light emitting diode.Model C is by the signal of port one output drive light emitting diode, and model D is by the signal of port 2 output drive light emitting diodes.
Fig. 4 is the process flow diagram that is used to illustrate the control method of embodiments of the invention.Each step wherein will be described in detail belows.
At first, in hardware unit, distribute an ID (S10) according to each model.When two models are arranged this embodiment, can use a single straight fork to close and distribute the ID of two models simply.If the model number is to be equal to or greater than at 2 o'clock, a model ID can be closed by straight fork and distribute, and as the minimum value in the integer, it is more than or equal to Log
2N.If used mould-number (A/D) transducer, the ID of so various models can be distributed by one of the working voltage bleeder circuit single analog input port.
Then, define a function pointer and a specific model function (S20).In table 1, the processing procedure of function pointer and the function that defines the light emitting diode that is switched on or switched off model C and D is by the C language Symbols.Coding L100 to L106 defined function pointer Fn_LED_On and Fn_LED_Off, function F n_LED_On_C and Fn_LED_Off_C are used to control the light emitting diode (LED) of model C, and the light emitting diode of function F n_LED_On_D and Fn_LED_Off_D definition model D.Grammer " the port1|=0x1 of L103; " be and " port1=port1|0x1; " identical, it is illustrated in not that the data of coordination are sent under the situation of port one, and the light emitting diode that promptly is connected to port one is switched on, and then last quilt " 1 " replaces.Grammer " the port1﹠amp of L104;=～0x1; " be and " port1=port1﹠amp;～0x1; " identical, it is illustrated in not that the data of coordination are sent under the situation of port one, and when the light emitting diode that promptly is connected to port one was disconnected, last quilt " 0 " replaced.L105 has the meaning similar to L100 to L104 with L106.
Table 1
L100?typedef?void(*VFnDef)(void)
L101?VFnDef?Fn_LED_On，Fn_LED_Off；
L102?int?port1，port2，port3；
L103?void?Fn_LED_On_C(void){port1|=0x1；}
L104?void?Fn_LED_Off_C(void){port1＆=～0x1；}
L105?void?Fn_LED_On_D(void){port2|=0x1；}
L106?void?Fn_LED_Off_D(void){port2&=～Ox1；}
……………..
Then, discern a model ID (S30).After the input of port 3 is identified, if the input of port 3 is " 0 ", think that so then hardware unit is model D, if the input of port 3 is " 1 ", think that so then hardware unit is a model C.
Then, a specific model function is assigned to function pointer (S40).In table 2, the processing procedure of function of distributing the light emitting diode be switched on or switched off model C and model D to a function pointer is by the C language Symbols.Coding L200 to L207 partition function pointer Fn_LED_On and Fn_LED_Off give corresponding function.L201 and L202 mean that after the input of port 3 is identified a function pointer Fn_LED_On is assigned to function F n_LED_On_D.Input at port 3 is under the situation of " 0 ", and promptly hardware unit is identified as model D, and when the input of port 3 was " 1 ", when promptly hardware unit was identified as model C, function pointer Fn_LED_Off was assigned to function F n_LED_Off_D.L204 and L205 have the meaning similarly with L200 to L202.
Table 2
L200?switch(port3){
L201?case?0：Fn_LED_On=Fn_LED_0n_B；
L202 Fn_LED_Off=Fn_LED_Off_B；
L203 break；
L204?case?1：Fn_LED_On=Fn_LED_On_A；
L205 Fn_LED_Off=Fn_LED_Off_A；
L206 break；
L207 }
A specific model function is used as recognition function pointer (S50) then.That is, do not consider model C or D, connect light emitting diode, and disconnect light emitting diode with Fn_LED_Off () with Fn_LED_On ().
Therefore, model C can be by software control mutually with D.Under the situation that model quantity increases, to increase function definition process and function assigning process, wherein control procedure is identical only.
As mentioned above, the hardware unit that the present invention's control has a plurality of models, wherein most of controlled variable are identical, it is different having only very little a part of parameter.So the exploitation of software and management afterwards can be carried out effectively.When increasing the new model of making by the existing model of upgrading, can provide effective management of hardware unit.
