Detailed Description
The application provides an expansion device and electronic equipment, which can realize the expansion of GPIO interfaces, so that a control chip can support more expansion functions.
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an expansion device provided by the present application, where the expansion device includes a control chip 01, a data transmission line 02 and an expansion module, and the expansion module includes a GPIO expander 32, a memory 31 and a function expansion module connected to the GPIO expander 32;
the control chip 01 is respectively connected with the GPIO expander 32 and the memory 31 through the data transmission line 02;
the memory 31 is used for storing pin occupation information of the GPIO expander 32 and read-write address information of the expansion module;
the control chip 01 is used for determining a function expansion module to be called according to the pin occupation information, and performing data interaction with the function expansion module to be called through the data transmission line 02.
In order to solve the limitation that the control chip 01 is limited by the GPIO pin number of the control chip 01 and can not expand various functions in the related art, the application provides an expansion device, which comprises the control chip 01, a data transmission line 02 and an expansion module, wherein the control chip 01 is connected with the expansion module through the data transmission line 02, the expansion module is internally provided with a function expansion module for realizing various expansion functions, and the control chip 01 realizes various expansion functions based on the structure.
Specifically, each expansion module in the present application includes a GPIO expander 32, a memory 31, and a function expansion module connected to the GPIO expander 32. The GPIO expander 32 in the expansion module is connected with a function expansion module, so that the control chip 01 is connected with the GPIO expander 32 through the data transmission line 02, and then the function expansion module is called through the GPIO expander 32. The data transmission line 02 may be an I2C bus or the like, and specifically may be selected according to actual situations, and the present application is not particularly limited; the function expansion module may also be selected according to actual requirements, for example, the function expansion module may include a DO (Digital Output) circuit, a DI (Digital Input) circuit, an LED indication circuit, and the like. The function expansion modules included in each expansion module may be the same, or may be configured adaptively according to different programs in accordance with the design of the electronic device, which is not particularly limited in the present application.
On the basis of the above structure, in order to facilitate the control chip 01 to call the function expansion module, the expansion module is further provided with a memory 31, where the memory 31 is used to store pin occupation information of the GPIO expander 32 in the expansion module, and the pin occupation information may include information such as connection condition of each pin of the GPIO expander 32 and a pin of the function expansion module and function of the connected function expansion module. Therefore, the control chip 01 can determine the extension functions supportable by the connected function extension modules based on the memories 31 in each extension module, and when the control chip 01 needs to realize the extension functions, the function extension module to be called is determined according to the pin occupation information stored in the memories 31; the memory 31 also stores the read-write address information of the expansion module, so that after the control chip 01 determines the function expansion module to be invoked, the control chip 01 can interact with the data of the function expansion module to be invoked through the data transmission line 02 based on the read-write address information, that is, the function expansion of the control chip 01 is realized.
In addition, since the pin occupation information of the GPIO expander 32 is stored in the memory 31 in the expansion module, when the function expansion module in the expansion module is increased or replaced, the pin occupation information of the GPIO expander 32 stored in the memory 31 is updated accordingly, the control chip 01 can use the updated function expansion module without redesigning a program, the operation is simpler, and the problem of error or damage when the function expansion module is called is avoided. In addition, if the expansion is fixed in the expansion position and the expansion is fixed, as is usual for chassis 1 and 2 slots to expand DO functions, and 3 and 4 slots to expand DI circuits, the DI circuits cannot be plugged into 1 and 2 slots. By the measure of the pin occupation information of the GPIO expander 32 of each function expansion module stored in the memory 31 in the application, the expansion position of the function expansion module can be changed, and the control chip 01 can not make errors when calling according to the stored information of the memory 31.
In addition, the control chip 01 can also determine the working state of the function expansion module in the expansion module by reading the read-write address information of the expansion module, if the control chip 01 can normally read the read-write address information of the expansion module, the function expansion module is connected to the GPIO expander 32, and the function expansion module can be normally used, namely is in the working state; if the control chip 01 cannot read the read-write address information of the extension module, it indicates that the GPIO extender 32 is not connected with the function extension module, that is, is in a non-callable state.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an expansion device provided by the present application, the number of expansion modules in fig. 1 can be expanded according to actual needs, a control chip 01 can be an MCU, a data transmission line 02 can be an I2C bus, the MCU is connected with a GPIO expander 32 and a memory 31 in each expansion module through the I2C bus, and the expansion modules include a DO circuit, a DI circuit and an LED circuit. The control chip 01 can arbitrarily expand the functions of the DO circuit, the DI circuit, the LED circuit and the like according to the requirements.
In summary, the expansion device provided by the application comprises a control chip 01, a data transmission line 02 and an expansion module, wherein the expansion module comprises a GPIO expander 32, a memory 31 and a function expansion module connected with the GPIO expander 32; the control chip 01 is respectively connected with the GPIO expander 32 and the memory 31 through the data transmission line 02; the memory 31 is used for storing pin occupation information of the GPIO expander 32 and read-write address information of the expansion module; the control chip 01 is used for determining a function expansion module to be called according to the pin occupation information, and performing data interaction with the function expansion module to be called through the data transmission line 02. The control chip 01 utilizes the data transmission line 02 and the expansion module to realize the expansion of the GPIO interface, so that the control chip 01 supports more expansion functions.
Based on the above embodiments:
as a preferred embodiment, the function expansion module in the expansion module includes any one or a combination of a plurality of data input module, a data output module and an indication module, wherein the data input module is a module for outputting data to the control chip 01, and the data output module is a module for receiving the data output by the control chip 01.
The function expansion module included in the expansion module in this embodiment includes a data input module, a data output module and an indication module, where the data input module is a module that outputs data to the control chip 01, and the indication module is similar to the data output module, and both are modules that receive data or instructions output by the control chip 01. The control chip 01 can realize a plurality of expansion functions by using the function expansion modules of the above types.
Specifically, when the data output module and the indication module are called, the control chip 01 determines the data output module and the indication module to be called according to the function to be expanded, that is, according to the pin occupation information stored in the memory 31, and then performs data transmission with the data output module and the indication module to be called through the data transmission line 02.
The data input module needs to output data to the control chip 01, and considering that a plurality of data input modules may exist in the expansion device, when the function expansion module is the data input module in the embodiment, the data input module firstly sends an interrupt request to the control chip 01 when the data input module needs to output data to the control chip 01, and then the control chip 01 polls and judges whether each data input module in the expansion device outputs data when receiving the interrupt request sent by the data input module; if yes, the data input module outputting the data is used as the data input module to be called, and the data output by the data input module to be called is read through the data transmission line 02.
As a preferred embodiment, the number of the expansion modules included in the expansion device is equal to or less than the power N of 2, and the read-write address information of each expansion module is different from each other, where N is the number of bits of the read-write address information of the expansion module.
In this embodiment, the control chip 01 achieves the purpose of data communication with the function expansion modules in the expansion modules based on the read-write address information of the expansion modules. In order to ensure that the control chip 01 can accurately communicate with the function expansion module to be called without calling other function expansion modules by mistake, the read-write address information of each expansion module in the embodiment is different from each other, that is, the read-write address information of each expansion module is unique. Based on this, the number of expansion modules included in the expansion device is limited by the number of bits of the read-write address information, and the number of expansion modules included in the expansion device is equal to or less than 2 to the power N.
Based on the above, the control chip 01 determines the target read-write address information corresponding to the function expansion module to be called according to the pin occupation information, and then performs data interaction with the function expansion module with the read-write address information conforming to the target read-write address information through the data transmission line 02, so that the purpose of function expansion is simply and reliably achieved.
As a preferred embodiment, the number of the expansion modules included in the expansion device is arbitrary, and the read-write address information of each expansion module can be changed and the default read-write address information of each expansion module is the same.
In this embodiment, the control chip 01 realizes the purpose of data communication with the function expansion modules in the expansion modules based on the read-write address information of the expansion modules, and in this embodiment, in order to make the number of the expansion modules not limited by the number of bits of the read-write address information, even if the number of the expansion modules included in the expansion device can be expanded to any number, default read-write address information is set for each expansion module, default read-write address information of each expansion module is the same, and the read-write address information of each expansion module is modifiable information, so that the read-write address information of the expansion module to be called by the control chip 01 is modified to be a unique address.
Based on the above, the control chip 01 determines the function expansion module to be called according to the pin occupation information, and modifies the read-write address information of the function expansion module to be called from the default read-write address information to the new read-write address information, so that the read-write address information of the function expansion module to be called is unique, and the control chip performs data interaction with the function expansion module with the read-write address information conforming to the new read-write address information through the data transmission line 02. For example, when the default read/write address information of each function expansion module has bit A0 and the I2C bus reads/writes, the control chip 01 sets the chip select signal of the function expansion module to high, so that bit A0 of the address of the function expansion module becomes 1. I2C bus reads and writes the chip that A0 is 1. After the read-write of the control chip 01 is completed, the chip select signal is released, namely the chip select signal is set low, so that the A0 bit of the address of the function expansion module is 0. The data transmission line does not allow the chip with the A0 bit of the read-write address being 0, and the read-write failure caused by the read-write address information conflict is avoided. For example, the PCA9539 chip has a default address of 0x74, and when the PCA9539 needs to be operated, the address is modified to 0x75, and the address is changed to 0x74 after the operation is completed.
In summary, the present embodiment solves the disadvantages that the number of expansion modules is limited and a fixed function expansion module can only be used at a fixed expansion position by modifying the read-write address information of the function expansion module to be called. The application dynamically changes the read-write address information of the function expansion module, and solves the problem of conflict of the read-write address information of the expansion module. The control chip transmits a chip selection signal through the data transmission line 02, so that default read-write address information of the function expansion module is changed, the read-write address information of the function expansion module needing to be read-written is always unique, and the read-write function is accurately completed.
The application also provides electronic equipment, which comprises any expansion device.
