Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description.
Before describing embodiments of the present invention in detail, a description is first given of a current method for enabling a communication controller.
Referring to fig. 1, a flowchart illustrating steps of a method for enabling a communication controller in the prior art is shown, where the electronic device may be an electronic device integrated with an embedded real-time operating system, such as a vxWorks operating system, and the electronic device may be integrated with an OTG controller for USB communication. In the starting process of the electronic device, the electronic device needs to perform an initializing operation on the OTG controller, after triggering the initializing operation on the OTG controller, the electronic device may reset a port physical layer (Port Physical Layer, PHY) clock of the OTG controller first, and then may set a depth of a receiving first-in first-out queue (First Input First Output, FIFO) and a depth of a transmitting FIFO of the OTG controller, write a depth value of the FIFO into a receiving capacity register, write a depth value of the FIFO into a transmitting capacity register, and clear a buffer of the receiving FIFO and a buffer of the transmitting FIFO. After the receive FIFO buffer and the transmit FIFO buffer are cleared, an enable operation to the OTG controller may be triggered, writing an enable value to an enable bit in a characteristic register of the OTG controller to enable OTG control. After writing the enable value into the enable bit, continuously reading the characteristic register to acquire the state value of the enable bit, and when the state value is consistent with the enable value, determining that the enabling operation of the OTG controller is successful, and starting the OTG controller, wherein the detection can be ended to end the enabling operation of the OTG controller. In contrast, when the state value is detected to be inconsistent with the enabling value, the characteristic register is continuously read until the state value is consistent with the enabling value, the detection is ended, and the enabling operation is ended.
As shown in fig. 1, when the state value of the enable bit is always inconsistent with the enable value, the enabling operation of the OTG controller fails, the electronic device may cycle through the characteristic register, acquire the state value of the enable bit, and compare the acquired state value with the enable value. At this time, the electronic device cannot end the enabling operation, and other steps after the enabling operation cannot be continued, so that the electronic device cannot be started normally.
One of the core concepts of the embodiments of the present invention is that an end time is set for an enabling operation, after an enabling value is written into an enabling bit, a timer is started, when the timer time reaches a preset end time, if the enabling operation fails, the enabling operation is directly ended, so that other steps after the enabling operation can be continued, and the electronic device can be started normally.
It should be noted that, the enabling operation is one step in the initializing process of the OTG controller, and before the enabling operation, the initializing steps such as resetting the PHY clock, setting the depth of the receive FIFO, setting the depth of the transmit FIFO, clearing the buffer of the receive FIFO, clearing the buffer of the transmit FIFO, and the like may be set, and at the same time, after the enabling operation is finished, other initializing steps may also be performed on the OTG controller continuously. After the initialization of the OTG controller is completed, the initialization of other devices such as a display, a network card, a keyboard and the like in the electronic device may be continued to start the whole electronic device. The initialization process of the OTG controller and the initialization process of the electronic device may be specifically set according to the requirements, which is not limited in this embodiment.
Referring to fig. 2, a flowchart illustrating steps of a method for enabling a communication controller according to the present invention may specifically include the following steps:
step 201, in response to an enabling trigger instruction of the communication controller, an enabling value is written into an enabling bit of the communication controller to start the communication controller, and timing is started.
The enabling trigger instruction is used for starting enabling operation on the OTG controller, and the enabling trigger instruction can be an enabling trigger instruction generated after the buffer memory of the receiving FIFO and the buffer memory of the sending FIFO are cleared in the initialization process of the OTG controller; alternatively, the enable trigger instruction may be generated after writing the depth value of the FIFO into the transmission capacity register. The enabling trigger instruction generating process may be specifically set according to the initializing process of the OTG controller, which is not limited in this embodiment.
Illustratively, the OTG controller's enable bit defaults to 0 and when the enable bit is set to 1, the OTG controller is enabled. The electronic device may write an enable value to the enable bit, i.e., the enable position is 1, in response to the enable trigger instruction. While the enabled position is 1, the electronic device may create and initiate a watchdog (watch) program that controls the watchdog program to start timing from zero. In practical applications, the electronic device may also perform timing in other manners, and the timing manner is not particularly limited in this embodiment.
Step 202, detecting the enable bit of the write enable value continuously to obtain the state value of the enable bit.
In this embodiment, after writing the enable value to the enable bit and starting the timer, the electronic device may continuously read the characteristic register to detect the state value of the enable bit, where the state value is the value of the enable bit in the current state. For example, after writing the enable value, the electronic device may read the characteristic register once every 1 millisecond, acquiring the state value of the enable bit once. After the state value is obtained, the state value of the enable bit may be compared with the enable value to determine whether the enable value and the state value agree. In combination with the above example, if the state value of the enable bit is 1, it may be determined that the state value of the enable bit is consistent with the enable value, and at this time, it may be determined that the enable bit is set, and the OTG controller is normally started; conversely, if the state value of the enable bit is 0, it may be determined that the state value of the enable bit is inconsistent with the enable value, at which point it may be determined that the enable bit is not set and the OTG controller is not enabled. The process of continuously detecting the enable bit by the electronic device may be set according to requirements, which is not limited in this embodiment.
Optionally, before the timing time reaches the preset end time, if the state value is consistent with the enabling value, determining that the enabling operation on the communication controller is successful;
the detection of the enable bit is ended to end the enabling operation of the communication controller.
In this embodiment, before the timing time reaches the preset end time, if it is determined that the state value of the enable bit is consistent with the enable value, the electronic device may determine that the enabling operation of the OTG controller is successful, and the OTG controller is normally started, and may end the detection of the enable bit at this time to end the enabling operation of the OTG controller. In contrast, before the timing time reaches the preset end time, if the state value of the enabling bit is inconsistent with the enabling value, the electronic device can determine that the enabling operation of the OTG controller fails, the OTG controller is not normally started, at this time, the characteristic register can be continuously read, the state value of the enabling bit is obtained, and the state value and the enabling value are continuously compared.
Step 203, when the timing time reaches the preset end time, if the state value is inconsistent with the enable value, determining that the enable operation of the communication controller fails.
Step 204, ending the detection of the enable bit to end the enabling operation of the communication controller.
For example, the preset end time may be 1 second, and in combination with step 101, if the timing time of the watchdog program reaches 1 second, it is detected that the state value of the enable bit is still 0 and is inconsistent with the enable value, it may be determined that the enabling operation of the OTG controller fails, and the OTG controller is not started normally. At this time, the electronic device may stop reading the characteristic register, ending the detection of the enable bit, to end the enabling operation of the OTG controller. After finishing the enabling operation of the OTG controller, the electronic device may continue to perform other steps after the enabling operation, and set other characteristics of the OTG controller to complete the initialization of the OTG controller. And after the initialization of the OTG controller is completed, the devices such as the display, the network card and the keyboard can be continuously initialized so as to start the whole electronic equipment.
In the embodiment of the invention, the electronic equipment responds to the enabling trigger instruction of the communication controller, writes the enabling value into the enabling bit of the communication controller to start the communication controller, starts timing, continuously detects the enabling bit of the writing enabling value to acquire the state value of the enabling bit, determines that the enabling operation of the communication controller fails if the state value is inconsistent with the enabling value when the timing time reaches the preset ending time, and ends the detection of the enabling bit to end the enabling operation of the communication controller. In the process of enabling the OTG controller, if the electronic equipment determines that the enabling operation of the OTG controller fails when the preset ending time is reached, the enabling operation can be directly ended so as to continue to carry out other steps after the enabling operation, the problem that the initialization of the OTG controller cannot be completed due to the enabling failure can be solved, and therefore the electronic equipment can be started normally.
Meanwhile, before the electronic device is preset to end the time, if the enabling operation of the OTG controller is determined to be successful, the enabling operation can be directly ended, other steps after the enabling operation are continued, and the electronic device is started normally.
Referring to fig. 3, a flowchart illustrating steps of another method for enabling a communication controller according to the present invention may specifically include the following steps:
step 301, in response to an enabling trigger instruction of the communication controller, writing an enabling value into an enabling bit of the communication controller to start the communication controller, and starting timing.
Step 302, detecting the enable bit when the timing time reaches the preset detection time, and obtaining the state value.
The preset detection time is smaller than the preset ending time.
In one embodiment, the electronic device may detect the enable bit at a preset detection time to reduce the number of times the enable bit is detected. In combination with the above examples, the preset detection time may be 0.2 seconds, 0.4 seconds, 0.6 seconds, and 0.8 seconds. The electronic device may read the primary characteristic register when the timing time reaches 0.2 seconds, detect the state value of the primary enable bit, and read the primary characteristic register when 0.6 seconds and 0.8 seconds, respectively, to detect the state value of the enable bit during the timing process of starting the watchdog program. The preset detection time may be specifically set according to requirements, which is not limited in this embodiment.
In practical application, after writing the enable value into the enable bit, the OTG controller needs a certain time to enable the enable bit 1, and the electronic device detects the enable bit in a preset detection time, so that frequent detection of the enable bit can be avoided, and power consumption of the electronic device can be reduced.
Step 303, if the status value is inconsistent with the enable value before the timing time reaches the preset end time, the enable value is rewritten into the enable bit to restart the communication controller.
In one embodiment, before the preset end time, if the electronic device detects that the state value of the enable bit is inconsistent with the enable value, the enable value may be rewritten into the enable bit to restart the OTG controller once again. In combination with step 302, if the state value obtained by the electronic device in 0.2 seconds is inconsistent with the enable value, the enable value may be rewritten to the enable bit to restart the OTG controller.
In practical application, before the preset end time, if the state value of the enabling bit is detected to be inconsistent with the enabling value, the enabling value can be written into the enabling bit again, so that the problem that the enabling value cannot be written due to writing errors is avoided.
Alternatively, step 303 may be implemented as follows:
when the timing time reaches the preset writing time, if the state value is inconsistent with the enabling value, the enabling value is rewritten into the enabling bit so as to restart the communication controller.
Wherein the preset writing time is smaller than the preset ending time.
In one embodiment, one or more preset write times may be set before the preset end time, and when the counted time reaches the preset write time, if it is detected that the state value is inconsistent with the enable value, the enable value may be rewritten to the enable bit. For example, the preset writing time may be 0.3 seconds, 0.5 seconds, 0.7 seconds, and 0.9 seconds, and when the electronic device reaches the timing time of 0.3 seconds, 0.5 seconds, 0.7 seconds, and 0.9 seconds, if the state value of the enable bit is detected to be inconsistent with the enable value, the enable value may be written to the enable bit again, so as to restart the OTG controller.
In practical application, in the rewriting process of the enabling value, the enabling value can be rewritten at a preset writing time point, and the enabling value can be prevented from being rewritten for many times, so that the power consumption of the electronic device is reduced. The number of writing of the enable value may be set according to the requirement, which is not limited in this embodiment.
And 304, when the timing time reaches the preset end time, if the state value is inconsistent with the enabling value, determining that the enabling operation of the communication controller fails.
Step 305, ending the detection of the enable bit to end the enabling operation of the communication controller.
In the embodiment of the invention, the electronic equipment responds to the enabling trigger instruction of the communication controller, writes the enabling value into the enabling bit of the communication controller to start the communication controller, starts timing, continuously detects the enabling bit of the writing enabling value to acquire the state value of the enabling bit, determines that the enabling operation of the communication controller fails if the state value is inconsistent with the enabling value when the timing time reaches the preset ending time, and ends the detection of the enabling bit to end the enabling operation of the communication controller. In the process of enabling the OTG controller, if the electronic equipment determines that the enabling operation of the OTG controller fails when the preset ending time is reached, the enabling operation can be directly ended so as to continue to carry out other steps after the enabling operation, the problem that the initialization of the OTG controller cannot be completed due to the enabling failure can be solved, and therefore the electronic equipment can be started normally.
Optionally, the method may further comprise, after step 305:
if the communication controller is detected to be connected to the universal serial bus device, rewriting an enabling value into the enabling bit to restart the communication controller;
upon detecting that the status value coincides with the enable value, it is determined that the enabling operation of the communication controller is completed.
In this embodiment, after finishing the enabling operation of the OTG controller, if it is detected that the OTG controller is connected to the USB device, the enable value may be written into the enable bit of the OTG controller again, so as to restart the OTG controller. For example, after the electronic device is started, the state of the OTG controller may be monitored, if it is monitored that the OTG controller is connected to the USB device, the electronic device may write the enable value into the enable bit of the OTG controller again, so as to start the OTG controller again, and when it is detected that the state value is consistent with the enable value, it is determined that the enabling operation of the OTG controller is completed. The detection method of the USB device may set this embodiment according to the requirement, which is not limited.
In practical application, after determining that the enabling operation of the OTG controller fails, if the USB device is detected to be connected, the electronic device may write the enabling value into the enabling bit of the OTG controller again, restart the OTG controller, and restart the OTG device under the condition that the OTG controller is connected to the USB device.
Optionally, the method may further include:
and when the state value is inconsistent with the enabling value, outputting prompt information to prompt that the enabling operation of the communication controller fails.
In this embodiment, when determining that the enabling operation of the communication controller fails, the electronic device may output a prompt message to remind the user. For example, the prompt information may be text information, and when the electronic device determines that the state value is inconsistent with the enable value, the electronic device may display a character string "OTG controller start failure" through the display screen, so as to remind the user of the OTG controller start failure. The specific type of the prompt information can be set according to the requirement, and the embodiment is not limited to this.
In practical application, when the OTG controller fails to be enabled, the electronic device outputs corresponding prompt information, so that a user can know the state of the OTG controller conveniently, and the user can conveniently adjust the using method of the electronic device.

Further, those skilled in the art will appreciate that the embodiments described in the specification are presently preferred embodiments, and that the acts are not necessarily required by the embodiments of the invention.
