Embodiment
Slant type idler wheel mouse circuit of the present invention mainly is to utilize general mouse left, center, right key to give the input end of microcontroller, a control circuit in parallel produces the mode of composite-key, and the firmware (Firmware) in the collocation micro controller detects the compound keys action, under the situation that does not increase micro controller I/O pin, increase the function that tilts, and then realize slant type idler wheel mouse move left and right s function.
See also Fig. 3, it is shown to be slant type idler wheel mouse circuit synoptic diagram of the present invention.This slant type idler wheel mouse circuit mainly comprises: a micro controller 50; This left, center, right push-button unit 22; This vertical moving roller unit 24; This moves horizontally push-button unit 42; An and control circuit 52.Wherein, this micro controller 50 also comprises: key signals input end 504, a right button signal input part 506 in the left button signal input part 502.A wherein end of the left button switch (LB) of this left, center, right push-button unit 22 is connected to the left button signal input part 502 of this micro controller 50; A wherein end of the middle bond switching (MB) of this left, center, right push-button unit 22 is connected to the middle key signals input end 504 of this micro controller 50; A wherein end of the right button switch (RB) of this left, center, right push-button unit 22 is connected to the right button signal input part 506 of this micro controller 50.And the other end of left button switch (LB), middle bond switching (MB), right button switch (RB) all is connected to voltage source (Vcc).
Moreover left bank switch (LTB) all is connected to voltage source (Vcc) with first end of right bank switch (RTB).And this control circuit 52 also comprises: one first diode (D1), one second diode (D2), one the 3rd diode (D3), and one the 4th diode (D4).Wherein, the P of this first diode (D1) and this second diode (D2) is connected to this second end that moves horizontally the left bank switch (LTB) of push-button unit 42 extremely jointly, and the N of this first diode (D1) and this second diode (D2) is connected to the left button signal input part 502 and the middle key signals input end 504 of this micro controller 50 extremely respectively.Moreover, the P of the 3rd diode (D3) and the 4th diode (D4) is connected to this second end that moves horizontally the right bank switch (RTB) of push-button unit 42 extremely jointly, and the N of the 3rd diode (D3) and the 4th diode (D4) is connected to the middle key signals input end 504 and the right button signal input part 506 of this micro controller 50 extremely respectively.
As shown in Figure 3, when user's "Left"-deviationist tilting mouse roller, this left bank switch (LTB) will conducting and with a high level signal via this first diode (D1) and second diode (D2), and then input to the left button signal input part 502 and the middle key signals input end 504 of this micro controller 50 respectively, and this right bank switch (RTB) will be not can conducting make right button signal input part 506 input low levels of this micro controller 50, this moment, micro controller 50 can be according to this left button signal input part 502, key signals input end 504 in being somebody's turn to do, the level (1 that this right button signal input part 506 is received, 1,0) carries out this horizontal left action.
Same, when user's Right deviation tilting mouse roller, this right bank switch (RTB) will conducting and with a high level signal via the 3rd diode (D3) and the 4th diode (D4), and then input to the middle key signals input end 504 and the right button signal input part 506 of this micro controller 50 respectively, and this left bank switch (LTB) will be not can conducting make left button signal input part 502 input low levels of this micro controller 50, this moment, micro controller 50 can be according to this left button signal input part 502, key signals input end 504 in being somebody's turn to do, the level (0 of these right button signal input part 506 received signals, 1,1) carries out the action that moves to right of this level.
Clearly, press and press right bank switch (RTB) and press by middle bond switching (MB) and right button switch (RB) simultaneously, microcontroller all can be received the signal of (0,1,1); In like manner, press and press left bank switch (LTB) and press by middle bond switching (MB) and left button switch (LB) simultaneously, microcontroller all can be received the signal of (1,1,0).For fear of the generation of this situation, this moment can be by defined effective time in the micro controller firmware, section be come judge.
In general, when the user presses two buttons simultaneously, for example when left button (LB), middle key (MB), the left button signal input part 502 of micro controller 50 and middle key signals input end 504 also can't accurately receive high level signal at the same time.That is to say that when the user pressed left button (LB), middle key (MB) simultaneously, the time that the left button signal input part 502 of micro controller 50 and middle key signals input end 504 receive high level signal can differ more than the 100ms.And when the user pressed right bank switch (RTB), the left button signal input part 502 of micro controller 50 and middle key signals input end 504 almost can receive high level signal simultaneously.
Therefore, according to embodiments of the invention, for example utilize the sampling frequency of 10Hz can be in the effective time of every 100ms section the signal level on key signals input end 504, the right button signal input part 506 in this left button signal input part of sampling 502.If the time point gap of right button signal input part 506 and middle key signals input end 504 received high level signals greater than this during section effective time, then the micro controller firmware can judge that right button signal input part 506 and middle key signals input end 504 received high level signals are respectively from the right button switch (RB) and the middle bond switching (MB) of left, center, right push-button unit 22, so microcontroller 50 action that can the output level do not move to right.
Otherwise, left button signal input part 502 receives low level signal if the right button signal input part 506 of micro controller 50 and middle key signals input end 504 receive high level signal, and the time point of the high level signal that right button signal input part 506 is received and the time point gap of middle key signals input end 504 received high level signals less than this during section effective time, then the micro controller firmware can judge that right button signal input part 506 and middle key signals input end 504 received high level signals are the 3rd diode (D3) and the 4th diodes (D4) from control circuit 52, then micro controller 50 action that will the output level moves to right.
As known from the above, by the firmware in the control circuit 52 of the present invention and the micro controller 50 of arranging in pairs or groups, under the situation that does not increase micro controller I/O pin, can realize the move left and right s function of slant type idler wheel mouse, that is to say, utilize control circuit 52 of the present invention can make optical mouse or laser mouse have the function of left and right shifting axle.Certainly, the present invention is not limited to realize the horizontal left action via left button signal input part 502, middle key signals input end 504, also is that the horizontal left action can be reached via left button signal input part 502, middle key signals input end 504,506 arbitrary groups of I/O pins of right button signal input part.Same, the present invention is not limited to via the action that moves to right of middle key signals input end 504, right button signal input part 506 realization levels, also is that the level action that moves to right can be reached via left button signal input part 502, middle key signals input end 504,506 arbitrary groups of I/O pins of right button signal input part.
In sum; though the present invention with the preferred embodiment explanation as above; yet it is not in order to limit the present invention; one skilled in the art; do not breaking away within the spirit and scope of the present invention; when doing various changes and retouching, therefore, protection scope of the present invention is as the criterion when looking accompanying Claim book restricted portion.
