Moreover, the addition of the external device of the pedal plate is to some extent to add extra shortcut key skills to players, the traditional pedal plate is connected with a PC host computer through a USB interface or a wireless form such as bluetooth, and the host computer responds to the operation of the pedal plate, which will occupy part of the resources of the host computer to some extent, and because the host computer is connected with a plurality of external devices, such as: keyboard, mouse and headset, etc. when the game is going on vigorously, the simultaneous operation of multiple peripherals may interfere with each other, and such errors will be fatal to professional competition.

In one embodiment, as shown in fig. 2, the display includes a display body 10 and a peripheral signal input interface 103, a display operating circuit is disposed on the display body 10, and the peripheral signal input interface 103 is electrically connected to the display operating circuit.

In the embodiment of the present application, after the peripheral signal is accessed through the peripheral signal input interface 103, the control circuit 102 of the display body 10 directly outputs the corresponding display signal according to the peripheral signal, so as to directly control the display effect of the display body 10 through the external device 20, and there is no need to implement control through a plurality of keys or a peripheral connected to the host, thereby greatly reducing the time for the display to adjust the image quality effect. Alternatively, the external device 20 may be a foot pedal. Notably, the display signal includes brightness, contrast, saturation, OSD sight icon, and the like.

Optionally, the display operating circuit includes a control circuit 102 and a memory 101 electrically connected to the control circuit 102, and the peripheral signal input interface is electrically connected to the control circuit.

And the display signal of the display and the display signal of the control signal of the host can be separated and do not interfere with each other.

Optionally, the memories correspond to different peripheral signals one to one, and each memory may store the display signal corresponding to the different peripheral signal, so as to further increase the display speed of the display.

Alternatively, the memory may be a general memory type such as a register or a flash memory.

Based on the above circuit, taking the external device 20 as a foot pedal as an example, the following data processing scheme can be adopted to implement the present application:

the foot pedal is connected with the control circuit 102 through the peripheral signal input interface 103, the foot pedal can be used as a shortcut key of an OSD menu key on the outer frame, the foot is placed on the pedal, the front foot pedal is pressed down all the time, the peripheral signal representing the continuous pressing of the front foot pedal is transmitted to the control circuit 102, the control circuit 102 receives the peripheral signal, the attributes of brightness, contrast and the like which are required to be increased at present are known according to the peripheral signal, the control circuit 102 is additionally provided with a display signal in a corresponding memory for outputting the display signal to the function menu at the OSD side, the OSD automatically adjusts the brightness and the contrast of the display attribute at the background, the peripheral signal representing the loosening of the front foot pedal is transmitted to the control circuit 102, the control circuit 102 receives the peripheral signal, the control circuit 102 outputs the display signal in the corresponding memory according to the peripheral signal, and transmits the display signal to the OSD function menu, gradually restoring the previous image quality attribute state; the same rear foot pedal continuously presses the foot pedal, the control circuit 102 outputs a corresponding display signal in the memory according to the external signal, the display signal is transmitted to the OSD function menu, the saturation of the picture is continuously adjusted, and when the rear foot pedal is released, the picture effect is gradually restored to the previous default state. And continuous pressing within 1 second at half sole interval of the lower foot can make the second IO port connected with the rear foot pedal detect two potential changes, can directly pop up the auxiliary gun center for OSD drawing, and the match center called by the keyboard and the mouse is matched, so that the match rate is improved.

Alternatively, the control circuit may be implemented by a chip of model MST9U13Q 1.

Based on the above circuit, taking the external device 20 as a foot pedal as an example, the peripheral signal input interface 103 includes a first IO port and a second IO port, as shown in fig. 5, the following data processing scheme may be further adopted in the present application:

s1, acquiring an electrical signal of the external device 20 and encoding the electrical signal to acquire a digital signal;

the front pedal of the pedal is connected to the first IO port GPIO1, the rear pedal is connected to the second IO port GPIO2, and the first IO port GPIO1 and the second IO port GPIO2 are both in a pulled-up (i.e., high level) state by default, which is denoted as state 1, and it is assumed that the port address of the first IO port GPIO1 is 0x01, and the port address of the second IO port GPIO2 is 0x 02. When the current pedal plate is stepped on, a continuous electric signal (voltage analog signal) can be provided for the port of the first IO port GPIO1, after the first IO port GPIO1 receives the voltage signal, the state of the first IO port GPIO1 is pulled down (low level state), which is recorded as state 0, when the current pedal plate is loosened, the voltage analog signal disappears, the state of the first IO port GPIO1 is pulled up again, and the state 1 is recorded. Similarly, when the rear foot pedal is stepped on, a continuous electric signal (voltage analog signal) is provided to the port of the second IO port GPIO2, the voltage analog signal is different from that provided to the first IO port GPIO1 by the front foot pedal, after the second IO port GPIO2 receives the voltage analog signal, the state of the second IO port GPIO2 is pulled down, and we remember the state 0, when the rear foot pedal is released, the voltage analog signal disappears, and the state of the GPIO2 is pulled up again, which is recorded as the state 1.

The control circuit 102 converts the change of the analog voltage signal monitored by the GPIO port into a digital signal, which may be a bit simple, for example, the electrical signal at the port of the second IO port GPIO2 is default to be high potential 1, the rear foot pedal is stepped on twice within 1 second, when the second IO port GPIO2 detects the input of the electrical signal (voltage analog signal), the second IO port GPIO2 is pulled down to low potential 0, when the foot is released for the first time, the input voltage disappears, the second IO port GPIO2 changes from the low potential 0 state to the default high potential 1 state, when the rear foot pedal is stepped on for the second time, the port of the second IO port GPIO2 changes from high potential 1 to low potential 0, when the foot leaves the rear foot pedal again, the potential reverses once again, and changes from low potential 0 to high potential 1, and the repeated change process of the potential can be converted into a string of digital signals 0x100x 010x100x 01. The first IO port GPIO1 is set to be at a high potential of 1 by default, becomes at a low potential of 0 when a voltage analog signal is input, and then keeps the first IO port GPIO1 at a low potential of 0 all the time when the foot pedal is not pressed, so we can simply regard the action of pressing the front foot pedal not pressed as transmitted digital signal data 0x100x 000x00, and the port address of the first IO port GPIO1 which we default is 0x01, so we can convert the action of pressing the front foot pedal into a string of digital signals 0x010x100x 000x 000x 00.

Similarly, when the rear foot pedal is stepped on, the port of the GPIO2 is defaulted to be high potential 1, and becomes low potential 0 when a voltage analog signal is input, then under the condition that the foot pedal is not stepped on, the port of the GPIO2 is always kept at low potential 0, so that the action of stepping on the rear foot pedal can be simply regarded as transmitted digital signal data 0x100x 000x00, the port address of the GPIO2 is 0x02, so that the action of stepping on the rear foot pedal can be converted into a string of digital signals 0x020x 100x 000x00, and by adding head-to-tail verification, the action of stepping on the rear foot pedal can be converted into an actual digital signal 0xaa 0x020x 100x 000x 000 xff; if the rear foot pedal corresponding to the GPIO2 port is stepped on twice within 1 second as described above, the digital signal corresponding to the two successive steps is 0xaa 0x020x 100x 010x100x 010 xff.

S2, determining the corresponding memory address according to the digital signal and reading the prestored numerical value;

because the memory address can change along with the change of practical application, here, only need define the memory address that different digital signals correspond in advance, regard the numerical value size of predetermineeing as the numerical value of prestoring and store in the memory, can confirm the corresponding memory address and read the prestoring numerical value wherein according to the digital signal, for example: a pre-stored value of 50 saturation is stored in the memory at address 11111111, and when the digital signal represents a command to adjust saturation, i.e. the corresponding memory address is 11111111, the pre-stored value is 50. The pre-stored values may be the brightness, contrast, and saturation values commonly used by the user.

S3, continuously acquiring the encoded digital signal of the external device 20, and increasing the value in the memory based on the pre-stored value at a preset speed when the memory address determined by the next digital signal is the same as the memory address determined by the previous digital signal; when the memory address determined by the next digital signal is different from the memory address determined by the previous digital signal, resetting the value in the memory determined by the previous digital signal to a pre-stored value.

In the above embodiment, when the memory a1 determined by the next digital signal is identical to the memory address a2 determined by the previous digital signal, i.e., a1 is equal to a2 is equal to a 11111111111, the value in the memory is increased on the basis of the pre-stored value at a preset speed, for example, the value in the memory is continuously increased on the basis of the pre-stored value of 50, for example, the value in the memory is increased at a speed of 5/s, thereby realizing rapid adjustment of brightness, contrast and saturation, and increasing the relevant value so that the display can rapidly brighten the bright scene and the dark scene in the game picture. When the memory address determined by the next digital signal and the memory address determined by the previous digital signal indicate that the previous parameter does not need to be adjusted, the previous parameter is adjusted to the common value. Thereby avoiding the eye injury of the user caused by the long-time over-strong screen display.

In one embodiment, as shown in fig. 6, after the step of acquiring the electrical signal of the external device 20 and encoding it to acquire the digital signal, the method includes:

and S4, when the digital signal is a preset digital signal, determining a corresponding memory address according to the digital signal, outputting the coordinates of the mouse to a memory corresponding to the digital signal, and displaying the coordinates of the mouse as an OSD sight icon on the display main body.

The OSD sight icon is a bitmap in a bmp format, the bitmap is divided into blocks according to a certain size (such as 12 × 18), each block is an individual pixel, a small pixel block is cut out in the horizontal direction 12 and the vertical direction 18, the pixel blocks are stored in a flash (fast memory) or SDRAM (synchronous dynamic random access memory) memory of a control circuit 102 of the display, when a digital signal converted by continuous treading of a rear foot pedal twice according to the above is triggered, a processing function takes out the stored pixel blocks from the memory, and the pixels are reassembled into the pixel blocks according to the mutual positions of the pixels according to the coordinates of the mouse to form a complete sight picture which is displayed on a picture of the display in a superimposed manner.

In one embodiment, the step of acquiring and encoding the electrical signal of the external device 20 to acquire the digital signal comprises:

encoding the electrical signal according to a preset first rule;

the preset first rule may refer to a digital coding rule, for example, the high level is recorded as 1, the low level is 0, and the collected electrical signal within a period of time is coded into a digital signal with a format of 0x 00. It should be noted that the encoding rule can be set by the user, and the purpose of the invention can be achieved by adopting other encoding rules.

Encrypting the encoded electrical signal in a first preset mode to obtain a digital signal;

the control circuit 102 may encrypt the digital signal just transmitted to the first IO port GPIO1 through a specific verification algorithm, for example: with a simple addition of a leading check bit, a leading check bit of 0xaa and a trailing check bit of 0xff to the actual digital signal, the just-pedaled action may correspond to a simple digital signal of 0xaa 0x010x100x 000x 000 xff. With the verification of the first character and the tail character, the action of stepping on the rear pedal can be converted into an actual digital signal 0xaa 0x020x 100x 000x 000 xff; if the rear foot pedal is continuously stepped on twice within 1 second as described above, and the rear foot pedal corresponds to the second IO port GPIO2, the digital signal corresponding to the two continuous steps is 0xaa 0x020x 100x 010x100x 010 xff. Through the scheme, the data can be checked for missing and omission at the check and acceptance end, and the interference of a circuit on a digital signal in the transmission process can be avoided.

In one embodiment, the step of determining the corresponding memory address according to the digital signal and reading the pre-stored value therein comprises:

decrypting the digital signal in a preset second preset mode;

the second preset mode is to screen out the first character and the tail character used in encryption, the middle section of the first character and the tail character is an encrypted digital signal, and the first character and the tail character are removed after screening to obtain a decrypted digital signal.

And determining a corresponding memory address according to the decrypted digital signal and reading a prestored numerical value in the memory address.

Before the step of acquiring the electrical signal of the external device 20 and encoding the electrical signal to acquire the digital signal or before the step of determining the corresponding memory address according to the decrypted digital signal and reading the pre-stored value therein, the memory addresses corresponding to different digital signals need to be defined in advance, and the preset value is stored in the memory as the pre-stored value, that is, the corresponding memory address can be determined according to the digital signal and the pre-stored value therein can be read. In practical application, when we burn programs to a main board of a display, the programs store values of image quality elements such as brightness and contrast at fixed positions on a memory, and record the values and addresses of the elements, when different stepping actions of a foot pedal are converted into different digital data, a program of a cycle detection peripheral signal input interface 103 monitors that data corresponding to a first IO port and a second IO port of the foot pedal enter, a corresponding processing program judges according to information of the data, such as a front foot pedal stepping action, the program finds the memory address corresponding to the brightness and the contrast in the memory and reads the values in the memory, and the values are determined by a user common value (determined by the user common value) which is about a middle value 50 of 0-100 under the condition that the display is shipped by default, then the program will modify the value stored in the memory of brightness and contrast, the program of the display will detect the data change of the first IO port and the second IO port corresponding to the foot pedal all the time at intervals, the data of the first IO port and the second IO port will not change in the time when the foot pedal is stepped on, the program will continue to increase the value of contrast brightness according to the previous judgment until the value increases to the maximum value of 100, the voltage change will transmit a series of data to the first IO port and the second IO port again after the foot pedal is released, the program will reset the value in the memory of brightness contrast to the initialized 50 after monitoring the data, the corresponding processing procedure of stepping on the rear foot pedal and the rear foot pedal is similar.

In one embodiment, the display further comprises a peripheral operating circuit, and an output end of the peripheral operating circuit is connected with the peripheral signal input interface 103.

The peripheral operation circuit outputs a peripheral signal in response to an operation of the external device 20. Taking the pedal as an example, when the front pedal of the pedal is stepped on, the output peripheral signal is a low level signal, and when the front pedal of the pedal is released, the output peripheral signal is a high level signal. When the rear pedal of the pedal is stepped on, the output peripheral signal is a low level signal, and when the rear pedal of the pedal is released, the output peripheral signal is a high level signal.

In one embodiment, when the external device 20 is a foot pedal and the external operating circuit is a key, the following data processing scheme is adopted:

the control chip realizes the interrupt mechanism: and the exception vector table is a specific definition of certain specific addresses in the control chip. When an interrupt occurs, the abnormal vector table is used to inform the control chip to process the interrupt, when the control chip is designed, some specific addresses in the control chip are defined in advance as entry addresses of the specific exception (for example, 0x0000000 address is defined as a reset abnormal vector table address, the control chip automatically jumps to 0x00000000 address to execute an instruction when the reset exception occurs, and for example, the abnormal vector address corresponding to the external interrupt is 0x30000008, after the external interrupt occurs, the control chip automatically jumps to 0x30000008 address by hardware to execute the instruction), and the hardware already determines what the abnormal control chip automatically jumps to which address to execute the memory, and what the software needs to do is to fill the first address of a code for processing the exception into the abnormal vector address. The external interrupt is an interrupt generated by a GPIO port corresponding to the external interrupt through a device outside the control chip.

The peripheral signal input interface 103 comprises a plurality of GPIO ports, each GPIO port corresponds to a single key connection, and the control chip actively reads the level of each GPIO port at intervals so as to obtain key information; the interrupt mode is that the control chip realizes the setting of an interrupt handler ISR corresponding to the interrupt which is triggered by the GPIO, and when the external is pressed or bounced off, the external interrupt corresponding to the GPIO is automatically triggered, so that the interrupt handler ISR is executed, and the key information is automatically processed.

The key is implemented in the control chip using an external interrupt. The specific implementation method comprises the following steps: connecting the key circuit on the GPIO of the external interrupt, and then configuring the GPIO into an external interrupt mode. At the moment, a person presses a key to change the voltage of the key circuit, and the voltage can trigger external interruption corresponding to the GPIO so that the control chip executes an interruption processing program.
