[0033] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0034] In one embodiment, referring to Figure 1 and Figure 2 The micro-control system development platform includes a coding database, a writing module, and a compiling module; the micro-control system development platform can be implemented based on computer hardware and software systems.

[0035] The coding database stores functional information and principle information of multiple software driver modules; and each software driver module is identified by a unique corresponding code.

[0036] The writing module can be used to edit and generate a coding list according to the timeline and / or containing conditional restrictions, which is intuitively represented as executing each software driver module according to the timeline or executing each software driver module according to the conditional restrictions.

[0037] The compiling module compiles the above-mentioned code list into a first execution program, which is a machine language recognizable by the single-chip microcomputer and is used to be burned into the program memory of the single-chip microcomputer for execution.

[0038] The microcontrol system development platform of this embodiment realizes the compilation of the first execution program based on the code as the execution body, realizes the control function of the microcontrol system according to the software driver module in the code list, simplifies the development, and improves the development efficiency.

[0039] In one embodiment, the microcontrol system development platform also includes a simulation module, which is used to simulate the operation of the code list; the simulation module includes input interfaces and output interfaces of each software driver module, and is executed according to the order of the time axis and the conditional restriction relationship.

[0040] The development platform of this embodiment is used for preliminary verification of the functional design of the microcontroller system, which reduces the debugging time on the circuit board, shortens the debugging cycle, and improves the development efficiency.

[0041] In one embodiment, referring to Figure 1 and Figure 2 The microcontrol system development platform includes a time axis variable; the code representing each software driver module in the code list is configured with a time axis variable and the execution order of the software driver module is determined according to the value of the time axis variable. When the time axis variable of the code is 0, the corresponding software driver module is executed without time limit.

[0042] The microcontrol system development platform of this embodiment distinguishes between sequential execution and non-sequential execution of the software driver module, thereby improving the development capability of the first execution program.

[0043] In one embodiment, each code in the writing module in the microcontrol system development platform is also configured with data variables, so as to facilitate the configuration and modification of commonly used data.

[0044] In one embodiment, the coding list is implemented in the form of a table.

[0045] For example, the configuration programming of the electric water heater control circuit board sets the standard hardware circuit board driver module, which is coded as 001; it includes the temperature sensor driver module, which is coded as 123; the relay driver module, which is coded as 155; the set temperature driver module, which is coded as 102; the power switch driver module, which is coded as 115, etc.; the above information is stored in the coding database.

[0046] The code list configured on the microcontroller system development platform is as follows.

[0047] Timeline variables Input trigger module signal (can have multiple modules combined) Output drive module signal (can have multiple modules combined) Notes (mnemonic instructions) 0 001(x)==0 0 123(x)<123(x) 155(x)==0 0 123(x)>123(x) 155(x)==1

[0048] Time axis variable, 0 means no concern about time; other values ​​can represent relative start time offset or execution order.

[0049] The data variables in the brackets after the code are the data variables of the software driver module, which can be directly configured or modified. The actual meaning of the specific value is recorded in the function information of the code. For example, for the relay module class, 0 generally means closed and 1 means open.

[0050] The above configuration is a simple model of an electric water heater that works at a user-specified temperature; when the user powers on, if the measured temperature is lower than the temperature set by the user, the heating relay is turned on to start heating, and if the temperature is higher than the set temperature, the heating relay is disconnected.

[0051] The above coding list is compiled into a first execution program and stored in the first storage area for execution.

When the first storage area stores the first execution program and the second storage area stores the second execution program, the controller 1 can execute each software driver module of the second execution program according to the time axis variable and conditional restriction relationship of the first execution program.

[0054] The microcontrol system development device of this embodiment can develop and debug the microcontrol system by only modifying the first execution program and burning it to the first storage area, thereby improving development efficiency and shortening the development cycle.

[0056] The microcontrol system development device of this embodiment can realize that only the off-chip memory 2 is repeatedly erased during the modification of the first execution program, and the on-chip memory 3 can use a rewritable or non-rewritable type single-chip microcomputer, thereby reducing the cost of the single-chip microcomputer.

[0057] In addition, when the first execution program is modified, only the off-chip memory 2 is repeatedly erased and written, thereby extending the service life of the single-chip microcomputer and saving development costs.

[0058] In one embodiment, the off-chip memory 2 is an EEPROM; of course, the off-chip memory 2 may also be other types of program memory that can be erased and written multiple times and will not be cleared when the power is off.
