For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0041] For details, please refer to Figure 1 , Figure 1 which is a schematic flowchart of an embodiment of the device display method provided by the present application.

[0042] The device display method of the present application is applied to a device display system. The device display system at least includes a client and an intelligent device. Specifically, the intelligent device involved in the present application is essentially an open-source electronic prototype platform, including but not limited to: Arduino, BeagleBone, Raspberry Pi, etc.

[0043] Among them, Arduino Uno is very common in the Maker community. Arduino has many different sizes and features, but in this application, Arduino Uno is selected as a representative. It is a very easy-to-develop platform, and many developers also choose it as a development environment. Moreover, its design makes it easy to connect to other devices. Compared with Arduino, Raspberry Pi is a relatively new member. It is actually an embedded computer, and it is also a full-featured desktop computer that is not expensive. It is a barebones system, and as a low-cost computer, it is a good platform for many projects. BeagleBone has good compatibility and can be used in many projects. It is a powerful Linux computer and can be installed in an Altoid's container.

[0044] In the subsequent description of the embodiments, the present application continues to introduce Arduino as the intelligent device in the device display system:

[0045] As Figure 1 shown, the specific steps are as follows:

[0046] Step S11: The client establishes a connection with the intelligent device.

[0047] In an embodiment of the present application, a client, such as a handheld terminal, establishes a communication connection with an Arduino smart device. The connection methods include, but are not limited to, wired connection or wireless connection. When connected by wire, the handheld terminal can directly connect to the communication interface of the Arduino smart device, or can be connected through other local terminals, that is, both the handheld terminal and the Arduino smart device are wired to the local terminal, and the local terminal is used as a transfer station for data and signal interaction. When connected wirelessly, the handheld terminal can connect to the same local area network as the Arduino smart device, or can establish a one-to-one hotspot connection with the Arduino smart device.

[0048] Specifically, after the Arduino smart device pre-written with the hotspot program is powered on, it will display the QR code of the hotspot information of the current smart device on the screen. The user can scan the QR code of the hotspot information on the Arduino smart device through the handheld terminal to obtain the hotspot connection information of the Arduino smart device. Among them, the hotspot connection information of the Arduino smart device includes the hotspot account and the hotspot password. After the handheld terminal successfully logs in to the hotspot through the hotspot connection information, it can establish a connection with the Arduino smart device, and the user enters the web management interface of the Arduino smart device through the handheld terminal.

[0049] Step S12: The client compiles the input image into a binary file and sends the binary file to the smart device through the connection.

[0050] In an embodiment of the present application, the user inputs the output content to be displayed on the screen of the Arduino smart device, such as an image, through the client in the web management interface of the Arduino smart device. Then, the client compiles the image into a binary file and sends the binary file to the Arduino smart device through the connection established in step S11.

[0051] It should be noted that at the client side, the source data to be processed can be any kind of data, such as image data, video data, signal input data, etc. The data processed by the client, that is, the data that needs to be transmitted to the Arduino smart device, must be unified into a binary file. In this application, through the computing power of the client, all data is unifiedly processed for the Arduino smart device at the front end. Thus, the Arduino smart device does not need to update the firmware. For all display tasks, the Arduino smart device only needs to have the ability to process binary files.

[0052] For the process of the client in this application compiling the binary file, please continue to refer to Figure 2 , Figure 2 is Figure 1 the specific process schematic diagram of step S12 of the device display method shown.

[0053] As Figure 2 shown, the specific steps are as follows:

[0054] Step S121: The client binarizes the input image to obtain the binarization value of each pixel point in the image.

[0055] In the embodiment of the present application, the client binarizes the image input by the user, and binarizes the image pixels in the pixel range of 0-255 into values of 0 and 1. For example, taking 128 as the binarization threshold, the pixel with an image pixel value of 90 has a binarization value of 0; the pixel with an image pixel value of 130 has a binarization value of 1.

[0056] Step S122: The client compiles the binarization values of each pixel point in sequence according to the pixel point order of the image to obtain a binarization value group.

[0057] In the embodiment of the present application, the client compiles the binarization values of each pixel point according to the pixel point order of the image to obtain a binarization value group. The binarization group of the image pixels {20, 50, 90, 200, 80, 250} is {0, 0, 0, 1, 0, 1}.

[0058] Step S123: The client compiles the binarization value group into a binary file.

[0059] In the embodiment of the present application, the client compiles the binarization group generated in step S122 into a binary file. For example, the binary file data representation of the binarization group {0, 0, 0, 1, 0, 1} is: {0x00, 0x00, 0x00, 0xff, 0x00, 0xff}.

[0060] Further, please continue to refer to Figure 3 , Figure 3 is a schematic diagram of the web interface of the Arduino intelligent device provided by the present application. As Figure 3 shown, the web interface of the Arduino intelligent device at least includes a file selection function, a threshold adjustment function, a file download function, and a size selection function. Users can perform front-end processing on the source data on the client through the above functions.

[0061] As Figure 3 shown, the user uploads a file through the file selection function. At this time, the file can specifically be an RGB format image file. The client binarizes the image file according to the binarization threshold currently set on the web interface. During this process, the user can flexibly set the specific value of the binarization threshold through the threshold adjustment button and view the schematic diagram after binarization processing on the web interface.

[0062] Further, the user can also generate an image file in real time by hand-drawing an image on the web interface. For example, the web interface can provide a graphics tablet or a drawing board. The user can manually draw a signature on the graphics tablet or manually draw on the drawing board. The client generates an image file based on the user's real-time input.

[0063] The user can also perform data preprocessing on the input image file by setting size conditions. For example, as Figure 3 shown, the user sets the width of the image to 100. If the image width of the image file is greater than 100, the client can automatically scale or crop the image file to adapt to the size conditions set by the user.

[0064] Step S13: The intelligent device displays the image based on the binary data in the binary file.

[0065] In the embodiment of the present application, the Arduino intelligent device obtains the binary file from the client through the connection established in step S11, and then updates the output content on the screen in real time according to the binary data in the binary file. For the specific output effect, please refer to Figure 4 .

[0066] Specifically, the Arduino intelligent device pre-writes a dynamic content display program for updating the screen output content in real time. The Arduino intelligent device sets the serial protocol that supports communication between the web browser and the Arduino intelligent device through the Arduino editor and compiles it into a binary file to be burned into the hardware of the Arduino intelligent device. The client uses the web serail API to transfer the binary file to the Arduino intelligent device through the above serial protocol and displays it on the screen of the Arduino intelligent device.

[0067] Specifically, at the display end of the Arduino intelligent device, the Arduino intelligent device can add a marquee display function. For example, before displaying the complete image, the Arduino intelligent device can first display the binarization value of each pixel in sequence according to the pixel position and binarization value in the binary file. After all pixels have been displayed once, the complete image is displayed. Further, in addition to the above marquee effect displayed in the order of pixel points, the Arduino intelligent device can also display the marquee effect in rows or columns, and other display methods are not specifically limited here.

[0068] In an embodiment of the present application, the client establishes a connection with the intelligent device; the client compiles the input image into a binary file and sends the binary file to the intelligent device through the connection; the intelligent device displays the image based on the binary data in the binary file. Through the above device display method, a low-performance intelligent device based on Arduino can utilize the computing power of the user's handheld terminal and the flexibility of web applications to dynamically update the screen output content without updating the firmware.

[0069] Those skilled in the art can understand that in the above method of the specific embodiment, the writing order of each step does not mean a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0070] To implement the above device display method, the present application also proposes an intelligent device. For details, please refer to Figure 5 , Figure 5 which is a schematic structural diagram of an embodiment of the intelligent device provided by the present application.

[0072] The processor 41, the memory 42, and the input / output device 43 are respectively connected to the bus 44. The memory 42 stores program data, and the processor 41 is configured to execute the program data to implement the device display method described in the above embodiment.

[0073] In an embodiment of the present application, the processor 41 can also be referred to as a CPU (Central Processing Unit). The processor 41 may be an integrated circuit chip with signal processing capabilities. The processor 41 can also be a general-purpose processor, a digital signal processor (DSP, Digital Signal Process), an application-specific integrated circuit (ASIC, Application Specific Integrated Circuit), a field-programmable gate array (FPGA, FieldProgrammable Gate Array), or other programmable logic devices, discrete gate or transistor logic devices, discrete hardware components. The general-purpose processor can be a microprocessor or the processor 41 can also be any conventional processor, etc.

[0074] The present application also provides a computer storage medium. Please continue to refer to Figure 6 , Figure 6It is a schematic structural diagram of an embodiment of a computer storage medium provided by this application. In the computer storage medium 600, there is stored a computer program 61, and when the computer program 61 is executed by a processor, it is used to implement the device display method of the above embodiment.
