Description

Technical Field

[0001] The present invention relates to the technical field of embedded board cards, and in particular to a method and device for controlling an indicator light of an embedded board card based on software programming. Background Art

[0002] Embedded boards are circuit boards equipped with a processor, various integrated circuits, interfaces, and other key components, all of which are assembled to perform specific functions, such as USB, Ethernet, serial ports, GPIO (general-purpose input / output ports), etc., in order to connect external devices and sensors.

[0003] Embedded boards typically use indicator lights to display the current device operating status or results. Typically, depending on application needs, boards include power indicators, status indicators (such as a network LINK indicator), data indicators (such as a network ACT indicator, serial port data receiving and sending indicators, and CAN port data receiving and sending indicators), switch indicator lights (off corresponds to a switch value of 0, on corresponds to a switch value of 1), and fault indicators (off in normal operation, on in the event of a fault).

[0004] The aforementioned indicators, primarily implemented through hardware control, can intuitively display operational and fault conditions. For example, if the serial port's data transmission indicator is off, problems with the serial port's data transmission can be quickly identified; if the board fault indicator is on, it indicates a board failure. However, in real-world applications, indicators are also needed to clearly indicate whether the system is operating normally, the causes of system failures, or the causes of startup failures. However, due to limited panel space on the board, adding more indicators to display a wider range of operational conditions is not feasible.

[0005] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. Summary of the Invention

[0006] The purpose of the present invention is to provide an embedded board indicator light control method and device based on software programming to solve the problem in the prior art that due to the limited panel space on the board, more indicator lights cannot be set to display more operating states.

Obviously, the drawings described below are one embodiment of the present invention. Those skilled in the art can also derive other drawings based on these drawings without inventive effort:

[0033] The scheme proposed in the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. According to the following description, the advantages and features of the present invention will be clearer. It should be noted that the drawings are in a very simplified form and use non-precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the implementation methods of the present invention. In order to make the purposes, features and advantages of the present invention more obvious and easy to understand, please refer to the accompanying drawings. It should be noted that the structures, proportions, sizes, etc. illustrated in the drawings of this specification are only used to match the contents disclosed in the specification for people familiar with this technology to understand and read, and are not used to limit the limiting conditions for the implementation of the present invention, so they have no technical substantive significance. Any structural modification, change in proportional relationship or adjustment of size, without affecting the efficacy and purpose that can be achieved by the present invention, should still fall within the scope of the technical content disclosed by the present invention.

[0034] The present invention provides a software-programmable embedded board indicator light control method and device. Software-controlled indicator lights are configured to reflect system operating status and fault information by controlling the combination and dynamic display of multiple indicator light positions. Specifically, several software-programmable indicator lights are configured at the hardware level, with customizable light position combinations and meanings. The on / off control of the indicator lights is also implemented at the software level. This is described in detail below.

[0035] like Figure 1 As shown, an embodiment of the present invention provides an embedded board indicator light control method based on software programming, including step S101 and step S102.

[0036] Step S101: detecting the operating status of the embedded board in real time.

[0037] Step S102: When it is detected that the embedded board enters the target operating state, the on / off states of the plurality of indicator lights are controlled by I / O (Input / Output) access, wherein the on / off states of the plurality of indicator lights are different for different operating states.

[0038] Specifically, from the moment the embedded board is powered on, the central processing unit within the board begins real-time monitoring of the board's operating status. To intuitively identify whether the system is operating normally, the cause of system failures, or the cause of failures during the board startup phase, in this embodiment, the embedded board's operating status is monitored in real time during the execution of the BIOS, the BootROM boot program, and the application program.

[0039] Some operating states that require indicator light indication can be predefined as target operating states, for example, one or more of the following: power-on state, BIOS entry state, BIOS fault state, bootrom entry state, bootrom fault state, application entry state, application initialization fault state, application operation fault state, application normal odd cycle state, and application normal even cycle state can be set as target operating states, and a corresponding indicator light on / off state can be set for each state. The BIOS fault state can be further divided into multiple states based on the fault type, such as BIOS fault state 1 and BIOS fault state 2; the bootrom fault state can also be further divided into multiple states based on the fault type, such as bootrom fault state 1 and bootrom fault state 2; the application initialization fault state can also be further divided into multiple states based on the fault type, such as initialization fault state 1 and application initialization fault state 2; and the application operation fault state can also be further divided into multiple states based on the fault type, such as application operation fault state 1, application operation fault state 2, and application operation fault state 3.

[0040] When the board enters the corresponding operating state, the indicator lights are controlled to turn on and off through I / O access. Specifically, the sysOutByte function can be used to write 0 or 1 to the port corresponding to each of the plurality of indicator lights, where one of 0 and 1 indicates that the light is on and the other indicates that the light is off.

[0041] In this embodiment, four indicator lights may be used, and the correspondence between the indicator lights and the control bits for I / O access is defined as shown in Table 1 below.

[0042] Table 1

[0043]

[0044] In this embodiment, the on / off states of the four indicator lights can be pre-combined using BCD (Binary-Coded Decimal) codes (a maximum of 16 combinations can be displayed) and associated with different operating states. Table 2 shows only one example of a light position combination and its corresponding operating state definition.

[0047] The following Figure 2 Taking the board card operation process shown as an example, the solution of the present invention is described in detail.

[0048] Figure 2"Start" in the code indicates that the board is powered on. The card is detected to be in the powered-on state. At this point, the data to be written to the indicator light ports in the sysOutByte function is set to 0000 (as shown in Table 2), thereby controlling all four indicator lights to light up. The board then enters the BIOS state and detects that it has entered the BIOS state. At this point, the data to be written to the indicator light ports in the sysOutByte function is set to 1011, thereby controlling only light2 to light up, while the other indicators are all off. The BIOS then performs two key checks. If the check results in the first BIOS fault state, indicating that BIOS fault state 1 has been detected, the data to be written to the indicator light ports in the sysOutByte function is set to 1001, thereby controlling light2 and light3 to light up, while light1 and light4 are off. If the check results in the second BIOS fault state, indicating that BIOS fault state 2 has been detected, the data to be written to the indicator light ports in the sysOutByte function is set to 1100, thereby controlling light3 and light4 to light up, while light1 and light2 are off.

[0049] If both key points in the BIOS are checked normally, the system runs to the bootrom, and it is detected that it has entered the bootrom state. At this time, the data to be written to the indicator port in the sysOutByte function is set to 1010, so that light2 and light4 turn on, and light1 and light3 turn off. Then two key points are checked in the bootrom. If the check result is the first bootrom fault state, it means that bootrom fault state 1 is detected. At this time, the data to be written to the indicator port in the sysOutByte function is set to 1110, so that light4 turns on, and the other indicators turn off. If the check result is the second bootrom fault state, it means that bootrom fault state 2 is detected. At this time, the data to be written to the indicator port in the sysOutByte function is set to 0011, so that light1 and light2 turn on, and light3 and light4 turn off.

[0050] If both key points in the bootrom are checked without exception, the system runs to the application program and detects that it has entered the application state. At this time, the data to be written to the indicator port in the sysOutByte function is set to 1111, and all the indicators are turned off. Then, two key points are checked during the application initialization phase. If the check result is the first application initialization failure, it means that application initialization failure state 1 has been detected. At this time, the data to be written to the indicator port in the sysOutByte function is set to 0111, and light1 is turned on, and the other indicators are turned off. If the check result is the second application initialization failure, it means that application initialization failure state 2 has been detected. At this time, the data to be written to the indicator port in the sysOutByte function is set to 1101, and light3 is turned on, and the other indicators are turned off.

[0051] If there are no abnormalities in the two key point checks of application initialization, the system runs to the application cycle processing, and the application performs an operation status check during the cycle. If the first application operation failure is detected, it means that application operation failure state 1 is detected. At this time, the data to be written to the indicator port in the sysOutByte function is set to 0110, so that light1 and light4 are on, and light2 and light3 are off. If the second application operation failure is detected, it means that application operation failure state 2 is detected. At this time, the data to be written to the indicator port in the sysOutByte function is set to 0010, so that light3 is off and the other indicator lights are on. If the third application operation failure is detected, it means that application operation failure state 3 is detected. At this time, the data to be written to the indicator port in the sysOutByte function is set to 1000, so that light1 is off and the other indicator lights are on.

[0052] If there is no abnormality during the cycle, the normal odd cycle state or the normal even cycle state is set according to the parity attribute of the current cycle. If the normal odd cycle state is applied, the data to be written to the port of the indicator light in the sysOutByte function is set to 0100, so that light2 is turned off and the other indicator lights are on. If the normal even cycle state is applied, the data to be written to the port of the indicator light in the sysOutByte function is set to 0001, so that light4 is turned off and the other indicator lights are on, thereby realizing dynamic changes in the odd and even cycles of the indicator lights.

[0053] This embodiment provides several software-programmable indicator lights at the hardware level, allows for custom light position combinations and their meanings, and enables software-level control of the indicator lights. This invention is suitable for embedded boards where limited panel space makes it difficult to use digital tubes. By using software-programmable indicator lights and light position combinations, the invention provides intuitive display of system status and fault information.

[0055] The detection module 201 is used to detect the operating status of the embedded board in real time;

[0057] Furthermore, during the execution of the BIOS program, the bootrom boot program and the application program, the detection module 201 detects the running status of the embedded board in real time.

[0058] Furthermore, the target operating state includes one or more of the following operating states: power-on state, entering BIOS state, BIOS failure state, entering bootrom state, bootrom failure state, entering application state, application initialization failure state, application operation failure state, application normal odd cycle state, and application normal even cycle state.

[0059] Furthermore, the control module 202 is specifically configured to write 0 or 1 to the port corresponding to each of the plurality of indicator lights through the sysOutByte function, wherein one of 0 and 1 indicates that the light is on and the other indicates that the light is off.

[0060] Furthermore, the number of the indicator lights is 4, and the on and off states of the 4 indicator lights are pre-combined using BCD codes and bound to different operating states.
