Specific embodiment
Core of the invention is to provide a kind of method that optical module is compatible with low rate automatically, user can be convenient effectively into
The switching of row optical module rate.
In order to enable those skilled in the art to better understand the solution of the present invention, with reference to the accompanying drawings and detailed description
The present invention is described in further detail.Obviously, described embodiments are only a part of the embodiments of the present invention, rather than
Whole embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creative work premise
Under every other embodiment obtained, shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is compatible with the implementation flow chart of the method for low rate for optical module a kind of in the present invention automatically, it should
Method is applied in the MCU (Micro controller Unit, micro-control unit) of optical module, may comprise steps of:
Step S101: automatic to read the level value that the selection of hardware rate receives foot and the selection of hardware rate sends foot；Its
In, the selection of hardware rate receives foot and the selection of hardware rate sends foot and connect with host.
Wiring schematic diagram between MCU and subscriber's main station can be found in Fig. 2, and in Fig. 2, the RS0 foot of the MCU of optical module is made
It selects to receive foot for hardware rate, the RS1 foot of MCU is selected to send foot as hardware rate.It should be pointed out that in view of existing
Some RS0 feet and RS1 foot are usually idle state, therefore it is selected to be used for the scheme of the application, in other embodiments,
Other pins can be chosen to implement the scheme of the application according to actual needs.
When user needs to carry out the rate switching of optical module, it is only necessary to which sending relevant rate selection instruction to host is
Can, for example, user clicks " receiving velocity is height " this option shown on host, host can get corresponding reception
Rate chooses instruction, and then selects the level value for receiving foot to be set to the first level value hardware rate, while also by receiving velocity
Software register value is set as the first level value.Correspondingly, user clicks " transmission rate is height " this option, host can be obtained
It chooses and instructs to corresponding transmission rate, and then select the level value for sending foot to be set to the first level value hardware rate, simultaneously
Also transmission rate software register value is set as the first level value.
The voltage that the selection of hardware rate receives on foot can be high level, be also possible to low level, when being high level, i.e., firmly
Part rate selects to receive the level value of foot to be 1, and when being low level, hardware rate selects to receive the level value of foot to be 0.Correspondingly,
It may be 1 or 0 that the selection of hardware rate, which sends the level value of foot,.
Step S102: by the communication bus being connect with host, the automatic receiving velocity software register value obtained in host
And transmission rate software register value.
Under normal circumstances, MCU is obtained receiving velocity software register value and the selection of hardware rate receive the level value of foot
It is identical, that is to say, that when user carries out the switching of the receiving velocity of optical module, such as user selects optical mode in host side
The receiving velocity of block is high-speed, and receiving velocity software register value selects the level value for receiving foot just can be equal to hardware rate
First level value.Correspondingly, such as user selects the receiving velocity of optical module for low rate in host side, receiving velocity software is posted
The level value for depositing value and hardware rate selection reception foot just will do it switching, such as be equal to second electrical level value.
Certainly, under normal circumstances, MCU is obtained transmission rate software register value and the selection of hardware rate send the electricity of foot
Level values are also identical.
Receiving velocity software register value in host is commonly stored in register Byte 110, and in bit3, transmission rate is soft
Part register value is commonly stored in register Byte 118, in bit 3.Communication bus can also carry out according to actual needs setting and
It chooses, such as can be as shown in Figure 2, communication bus is chosen for widely used I2C (Inter-Integrated
Circuit, twin wire universal serial bus) communication bus.
Step S103: when receiving velocity software register value and the selection of hardware rate receive foot level value the two numerical value it
In any one be equal to the first level value when, the receiving velocity of optical module is chosen for high-speed automatically, otherwise automatically by light
The receiving velocity of module is chosen for low rate.
MCU can judge that receiving velocity software register value and the selection of hardware rate receive the level value of foot simultaneously, such as front
Description, under normal circumstances, receiving velocity software register value and hardware rate selection receive foot level value be it is identical, i.e.,
The first level value can be equal to or be not equal to the first level value.
The application is it is considered that the business of user is usually under the mode for operating in high-speed, only in client use environment
It changes etc. and just to need to operate under low rate mode in small parts occasion.I.e. customer service usually requires that the reception of optical module is fast
Rate and transmission rate are high-speed, and the application just combines the selection of hardware rate and the selection of software rate, compared to using single
One digit rate selection mode is conducive to avoid interfering, and improves serious forgiveness.
Specifically, under non-failure conditions, when receiving velocity is chosen for high-speed by user, the deposit of receiving velocity software
Value and hardware rate select the level value for receiving foot can be for equal to the first level value.If leading to hardware due to interference etc.
The level value that rate selection receives foot has occurred exception or receiving velocity software register value in transmittance process and sends out in transmittance process
Exception has been given birth to, just will appear receiving velocity software register value and the selection of hardware rate receives among the level value of foot, only one
Numerical value is equal to the case where the first level value.Since customer service is usually under the mode for operating in high-speed, MCU judgement
When any one among the two numerical value is equal to the first level value out, the receiving velocity of optical module is just chosen for high speed automatically
Rate just has bigger probability to meet the desired receiving velocity of user in this way, therefore also just improves serious forgiveness.
Further, it when the first level value is preset as 1 or is preset as 0, and can be set according to actual needs,
To further improve serious forgiveness.
Specifically, when the first level value is preset as 1, it will usually apply: hardware rate receives pin and is easy to appear electricity
The empty low or receiving velocity software register value in position is easy to cause register value to be become from 1 due to interference etc. in transmittance process
In 0 occasion.As can be seen that under non-failure conditions, when receiving velocity is chosen for high-speed by user, receiving velocity software
Register value and hardware rate select to receive the level value of foot be 1, but if there are a data exceptions in the two, such as by
In interference result in software rate selection communication abnormality, the receiving velocity software register value that MCU is got be 0, the numerical value 0 with
The level value 1 that the selection of hardware rate receives foot is different, MCU can logic or by way of carry out operation, i.e. numerical value 0 and numerical value
1 is used as or the input terminal of door, obtains a result as numerical value 1, meeting the first level value is 1, MCU just automatically by the reception of optical module
Rate is chosen for high-speed.That is, receiving velocity software register value and hardware rate selection receive foot level value this two
Among a numerical value any one be 1 when, the receiving velocity of optical module can be chosen for high-speed automatically by MCU.
The level value that receiving velocity software register value and the selection of hardware rate receive foot is not identical, i.e., one of them is 0, separately
One is 1, this illustrates at least one data, and there are mistakes.In this kind of embodiment, it is contemplated that it is frequent that hardware rate receives pin
Appearance potential void is low, is also easy to cause numerical value to be become by 1 due to interference etc. in the transmittance process of receiving velocity software register value
It is 0, therefore, when this error situation occurs, one in 2 data when being equal to the first level value 1, MCU just thinks user's phase
The receiving velocity of prestige is high-speed, the receiving velocity of optical module will be chosen for high-speed automatically.That is, being directed to hardware
Rate receives pin and is easy to appear that current potential void is low or receiving velocity software register value is in transmittance process, is easy due to interference
Etc. reasons cause register value from 1 become 0 occasion, set 1 for the first level value in this kind of embodiment, the optical mode selected
The receiving velocity of block has bigger probability to meet the desired receiving velocity of user, can also further increase failure tolerant rate.
In addition it is also necessary to which explanation, receives the level value of foot different from receiving velocity when the selection of hardware rate has occurred
The case where software register value, MCU can also send fault cues information to host, so that user can notice the feelings in time
Condition.
In another embodiment, the first level value is set as 0.Would generally apply: hardware rate receives pin and holds
Easy appearance potential virtual height or receiving velocity software register value are easy to cause to deposit due to interference etc. in transmittance process
In the occasion that value becomes 1 from 0.Specifically, receiving velocity software register value and the selection of hardware rate receive the level value not phase of foot
Together, i.e., one of them be 0, one of them is 1, in this kind of embodiment, as long as MCU judge it is any one in the two numerical value
A is 0, i.e., any value is equal to the first level value 0, the receiving velocity of optical module will be chosen for high-speed automatically.
For example, user selects the receiving velocity of optical module for high-speed on host, in this kind of embodiment, in positive reason
Under condition, receiving velocity software register value and hardware rate select to receive the level value of foot be 0.In case of abnormal conditions,
Such as since hardware rate selects the current potential virtual height of reception foot, the hardware rate selection for causing MCU to receive receives the level of foot
Value is 1, and since receiving velocity software register value is correct numerical value 0, the receiving velocity of optical module can be still chosen for by MCU automatically
High-speed, the receiving velocity for yet avoiding optical module caused by the hardware rate selection frequent current potential virtual height of foot do not meet user
It is expected that the case where, improve serious forgiveness.
Step S104: when transmission rate software register value and the selection of hardware rate send foot level value the two numerical value it
In any one be equal to the first level value when, the transmission rate of optical module is chosen for high-speed automatically, otherwise automatically by light
The transmission rate of module is chosen for low rate.
Step S104 is referred to the associated description in step S103, is not described in more detail here.
It should be pointed out that in practical applications, the first level value is usually preset as 1, i.e., in practical applications, due to dry
The case where reasons such as disturbing, the numerical value 1 in software communication or hardware communications is caused to become numerical value 0 is more universal, by the first level
Value setting 1 is conducive to improve serious forgiveness.
It should also be noted that, in general, selection of the user for the transmission rate of optical module, meeting and its for
The selection of the receiving velocity of optical module is identical, i.e., transmission rate and receiving velocity can be chosen for high-speed simultaneously by user, or
Transmission rate and receiving velocity are chosen for low rate simultaneously.But in small part occasion, can also there be transmission rate and be chosen for
The case where high-speed, receiving velocity is chosen for low rate or transmission rate are chosen for low rate, and receiving velocity is chosen for height
Rate, the application can be supported.
