Fig. 2 shows according to analogue-key waveform of the present invention.
Fig. 3 (A), (B) reach the master routine that (C) shows respectively according to micromonitor system of the present invention, the counting procedure and second of the first counting module is counted the flow process of the counting procedure of module.
Embodiment
For more understanding technology contents of the present invention, be described as follows especially exemplified by a preferred embodiment:
Fig. 1 shows a preferred embodiment of the electronics specification test macro of button of the present invention, it comprises a micromonitor system 11 and an electronic product 12 to be measured, micromonitor system 11 has a test pin position 111, electronic product 12 to be measured has at least one button 121, and 121 pairs of each buttons should have a button pin position 122.
The test pin position 111 of aforementioned micromonitor system 11 is connected to the button pin 122 of this electronic product 12 to be measured, and this micromonitor system 11 is to produce continuous analogue-key waveform 13 with the time counting of the first counting module 115 and the second counting module 116 in this test pin position, to test the corresponding button 121 of this electronic product 12.
For meet electronic product by bonding electron specification test request, as shown in Figure 2, aforementioned analogue-key waveform 13 is in a sample time S, and high levels that a duration T unclamps with the expression button, and the low level pressed with the expression button of duration S-T are provided.In addition, can also low level represent that button is pressed, high levels represents that button unclamps.Generally speaking, electronic installation is the level estimate with millisecond (ms) and microsecond (us), for example: sample time S=A * 1ms, duration T=B * 128us of unclamping of expression button, wherein A and B are positive integer, it can be adjusted according to the electronics specification.
For producing aforesaid analogue-key waveform 13, (A) of Fig. 3, (B) reach the master routine that (C) shows aforementioned micromonitor system 11 respectively, the counting procedure of the counting procedure of the first counting module 115 and the second counting module 116, in this micromonitor system 11, the counting procedure of the counting procedure of the first counting module 115 and the second counting module 116 is the timing interrupt routine, it interrupts master routine and is triggered and automatically performs after calculating a special time, wherein, the counting procedure of the first counting module 115 is that every 128us is triggered and automatically performs once, and the counting procedure of the second counting module 116 is that every 1ms is triggered and automatically performs once.
As shown in Figure 3, aforementioned master routine is that A and B are initialized as A=4, B=0, and test pin position 111 is initially set high levels, continues afterwards whether detecting A value is 0, and when A=0, A is made as 4 and will to test pin position setting be high levels again.
Be triggered and when carrying out at the counting procedure of the aforementioned first counting module 115, whether its detecting test pin position 111 is high levels, as otherwise return master routine, in this way, the B value is added 1 and detect the B value and whether reached 5, as otherwise return master routine, also will test pin position 111 is made as low level then the B value to be made as 0 in this way, owing to the counting procedure of the first counting module 115 is that every 128us is triggered and carries out once, therefore whether the first counting module 115 is to arrive in order to calculate the duration T that this expression button unclamps as can be known, that is, counting procedure at the first counting module 115 is triggered and after carrying out B=4 time, learn that duration T=4 * 128us arrives, and change the position standard of analogue-key waveform 13 into low level by high levels.
Be triggered and when carrying out at the counting procedure of the aforementioned second counting module 116, whether its detecting A value is 0, as denying, the A value is subtracted 1, then return master routine in this way, owing to the counting procedure of the second counting module 116 is that every 1ms is triggered and carries out once, therefore whether the second counting module 116 is to arrive in order to calculate this sample time S as can be known, that is, counting procedure at the second counting module 116 is triggered and after carrying out A=4 time, learn that sample time, S=4 * 1ms arrived, after returning master routine, change high levels into by low level with the position of analogue-key waveform 13 is accurate.So, just can produce continuous analog button waveform 13 up to specification in the test pin position 111 of this micromonitor system 11 by the counting procedure of aforementioned master routine, the first counting module 115 and the counting procedure of the second counting module 116, and can test the corresponding button 121 of electronic product 12.
By above explanation as can be known, the electronics specification test macro of button of the present invention is the continuous analog button waveform of being given birth to ms and us grade by micromonitor system from movable property, and can very verify the electronics specification of button accurately, also can be as efficient key testing instrument of designer, and can arbitrarily adjust the analogue-key waveform and have suitable elasticity.
The foregoing description is only given an example for convenience of description, and the interest field that the present invention advocated should be as the criterion so that claim is described certainly, but not only limits to the foregoing description.
