Embodiment
Basic thought of the present invention is: be provided with between CPU and GPIO pin and be connected CPLD, the internal register of being responsible for reading the PHY chip by CPU obtains information and writes CPLD, be shown with the pulse signal of GPIO on the PHY chip of transmitting-receiving bag by CPLD by direct monitoring form and handle, and the indication that comes the driving LED lamp by CPLD, by the control of CPLD, make a LED lamp that is adopted to indicate link setup and transmitting-receiving package informatin by user operation habits.
The device of realization Ethernet link setup provided by the present invention and the indication of transmitting-receiving bag comprises CPU, PHY chip, CPLD and a LED lamp.Wherein, the PHY chip is used to provide link setup information and transmitting-receiving package informatin; CPU is used for reading link setup information from the internal register of PHY chip, and the link setup information of obtaining is write the internal register of CPLD; CPLD is used for obtaining link setup information from CPU, obtains the transmitting-receiving package informatin from the PHY chip, and the indicating status of control LED lamp.Concrete, the address wire and the data wire of PHY chip are connected to CPU, and the part address wire of CPU links to each other with the IO pin of CPLD with data wire; Be used to indicate the GPIO pin of receiving and dispatching bag to be connected to the IO pin of CPLD on the PHY chip, the IO pin of CPLD links to each other with the LED lamp, and the driving LED lamp is indicated.
In the practical application, for link setup information, the PHY chip is kept in the register of self after receiving link setup information, the internal register that CPU reads the PHY chip obtains this link setup information, again the link setup information of being obtained is write the internal register of CPLD, CPLD can obtain described link setup information, the bright link setup of indicating of CPLD driving LED lamp then, and LED keeps bright state.
For the transmitting-receiving package informatin, when the transmitting-receiving package informatin was arranged, the PHY chip just provided the low level pulse of 100us width for CPLD, after CPLD receives the pulse of transmitting-receiving bag, can control the LED lamp and carry out the light on and off flicker, and expression is just at the transceive data bag.
In fact, LED lamp of the present invention relates generally to three states: the state of turning off the light, blink states and bright lamp hold mode, with these three states one to one information state be: not link setup state, transmitting-receiving bag state and link setup but do not receive and dispatch the bag state.Therefore, the present invention has set three state machines in CPLD, as shown in Figure 1, comprising: the state of turning off the light, bright lamp hold mode and blink states.When CPLD is in that the link setup state is not received link setup information, switch to bright lamp hold mode from the state of turning off the light.When CPLD is in bright lamp hold mode,, then switch to blink states from bright lamp hold mode if receive the pulse of transmitting-receiving bag; If receive chain rupture information, then switch to the state of turning off the light from bright lamp hold mode.When CPLD is in blink states,, then switch to the state of turning off the light from blink states if receive chain rupture information; If do not receive the pulse of transmitting-receiving bag at the appointed time, then switch to bright lamp hold mode from blink states.
Here, can set in advance the timer that duration is M for the described fixed time, this timer starts when entering blink states, initialization timing device when at every turn receiving the pulse of transmitting-receiving bag, if timer expiry was not received transmitting-receiving bag pulse, then switching state in illustrating at the appointed time.The described fixed time also can passing threshold be that the counter of M is finished, this counter begins counting when entering blink states, receive the zero clearing of transmitting-receiving bag pulse hour counter, if counter reaches threshold value at every turn, do not receive transmitting-receiving bag pulse, then switching state in illustrating at the appointed time.
Based on state exchange shown in Figure 1, the present invention realizes the detailed process of Ethernet link setup and the indication of transmitting-receiving bag, as shown in Figure 2, may further comprise the steps:
Step 201: during current not link setup, the LED lamp goes out.
Step 202～203:CPU is by reading the internal register of PHY chip, and whether real-time judge link setup, if do not read link setup information, then link setup not return step 202 and continue to judge, and the LED lamp keeps going out;
If CPU reads link setup information, then represent link setup, CPU output low level then writes the internal register of CPLD with the link setup information of obtaining, and after CPLD obtained link setup information, the driving LED lamp was bright.
Whether the real-time detection of step 204～205:CPLD receives the pulse of transmitting-receiving bag, if having, then the driving LED lamp begins or keeps flicker, and step 204 is returned in the clock zero clearing; Otherwise, execution in step 206.
Step 206～208: judge whether to arrive the fixed time, if then the driving LED lamp switches to Chang Liang, returns step 204; Otherwise, increase timing, return step 204.
Here, the fixed time can be that the timer of M or counter that threshold value is M are used as clock by setting duration, and the value of M is than broad, from 2s to 5s all in the scope of considering.
Among the present invention, need take the rate behavior of Ethernet into consideration to the control of LED lamp flicker frequency, such as: when sending the bag of 10M, 1000M speed, if directly transmitting-receiving bag pulse indication is received on the LED lamp, will be owing to pulse frequency is too high, make the user only see that LED is bright, can't reach the effect of flicker; And when the PC ping Ethernet interface, because the LED pulse is narrow, the user also can't see flickering effect.Therefore, can adopt two kinds of flashing modes among the present invention: a kind of is the response flicker, and a kind of is the fixed frequency flicker.Concrete, can set in advance a speed thresholding, for the bag of the transmitting-receiving at a slow speed situation that is lower than threshold value, can be by the FREQUENCY CONTROL LED lamp flicker of reality transmitting-receiving bag; Two-forty transmitting-receiving bag situation for surpassing thresholding can adopt the fixed frequency flicker, just controls the LED lamp and glimmers by some cycles, as long as the pulse duration of control flicker can the driving LED lamp, and can reach the discernmible scintillation time length of human eye and gets final product.
In order to control flicker frequency, the counter that need to preestablish a numerical value be N goes out at the bright half the time of N value time corresponding section inner control LED lamp half the time, and the N value can be regarded flicker cycle length as.To between the 0.5s, because be generally less than 0.2s, human eye just can't be differentiated the N/2 flicker of 0.1s just to the scope of N value at 0.2s; Will feel that greater than 0.5s flicker is too slow.
As shown in Figure 3, concrete LED lamp flicker control flow may further comprise the steps:
Step 301: to Counter Value N zero clearing, here, the initial indicating status of LED lamp is bright.
Step 302: judge whether to receive the pulse of transmitting-receiving bag, if receive, then execution in step 303; If do not receive, return step 302 and continue to judge.
Step 303～304: judge whether N is 0, if, then enabling counting, the LED lamp maintains the original state, and returns step 302; Otherwise, execution in step 305.
Step 305～306: judge whether Counter Value arrives N/2, if equal N/2, then N continues counting, and the LED negate is bright before the LED lamp that is:, becomes this moment to go out; For going out, brighten this moment, returns step 302 before; If less than N/2, the LED lamp maintains the original state, and returns step 302; If greater than N/2, then execution in step 307.
Step 307～308: judge whether Counter Value arrives N, if step 301 is returned in then LED negate; Otherwise the LED lamp maintains the original state, and returns step 302.
In the flicker control procedure, do not accept the pulse of any transmitting-receiving bag.Generally, if Counter Value N is provided with suitably, also can not distinguish fixed frequency flicker and response flicker, because minimum response flicker cycle is N.
The above is preferred embodiment of the present invention only, is not to be used to limit protection scope of the present invention.
