Further, an embodiment of the present disclosure provides a test circuit project output module 250 and an online program development-compilation module 260.

Another purpose of the present disclosure is to provide a method of implementing an online integrated microcontroller development tool. The method is implemented through the online integrated microcontroller development tool system 200. Refer to FIG. 2, which is a flowchart of a method of implementing an online integrated microcontroller development tool according to an embodiment of the present disclosure. In step S201, the client logins the online integrated microcontroller development tool system 200 via the computer device 100, and the client inputs the pin requirement information. Next, in step S202, the pin required module 210 selects the suitable model number from the database 220 according to the pin requirement information.

Taking a first example for further explanation, refer to FIG. 3, which is a schematic diagram of a first example of a pin requirement information and a functional component of the online integrated microcontroller development tool system according to an embodiment of the present disclosure. A client wants to make a microcontroller for a temperature sensor, and data of the temperature sensor can transmit to the computer device 100 (such as a computer or a mobile phone, etc.) via Wireless fidelity (WiFi). Hence, as shown in Table 1 below, the client selects a flash memory 128 Kb in the online integrated microcontroller development tool system 200 according to the requirements. The client inputs the pin requirement information, that is, requiring a serial peripheral interface bus (SPI) pin, a universal asynchronous receive/transmitter (UART) pin, a serial communication bus (such as an inter-integrated circuit (I2C)) pin, and so on.


Next, after the pin required module 210 receives the mentioned pin requirement information, the pin required module 210 selects a suitable model number (eg, MCU-300, but the present disclosure is not limited to this model number) from the database. Also, the pin required module 210 automatically arranges the pins on the microcontroller block corresponding to the suitable model number (MCU-300). The functional component module 230 selects the corresponding functional components, such as a temperature sensor 310, a WiFi module 320, a serial peripheral interface flash memory 330 (SPI flash), and other functional components. Then, the functional component module 230 makes the abovementioned functional components be connected to the microcontroller block with arranged pins to generate the corresponding circuit structure.


Describing in more detail, the 13th and the 14th pins are connected to the WiFi module 320. The 13th pin is a transmit data (TXD) pin of the UART, and the 14th is a receive data (RXD) pin of the UART. The 17th and the 18th pins are connected to the temperature sensor 310. The 17th pin is a serial clock (SCL) pin of the I2C to start or stop transmission and transmit a clock sequence, and the 18th is a serial data (SDA) pin of the I2C for transmission data. The 41st to 44th pins are SPI pins, and the 41th to 44th pins are connected to SPI flash 330. The 41st pin is a slave select (SS) pin of the SPI, the 42nd is a serial clock (SCLK) pin of the SPI, the 43rd is a master input, slave output (MISO) pin of the SPI, and the 44th is master output, slave input (MOSI) pin of the SPI.


It is understood that the suitable model number (MCU-300) of the first example has other functional pins. As shown in FIG. 3, the 1st to 6th, 47th and 48th pins are analog-to-digital signal pins, which can convert an analog signal collected by the temperature sensor 310 into a digital signal.


Alternatively, the client also reserves pins for future functions to be develop. For instance, if the client wants that temperature sensor 310 has an audio function, the client can reserve the SPI pins to connect to an audio module.

In an embodiment of the present disclosure, a microcontroller development combination kit (not shown in figures) is also provided. The microcontroller development combination kit includes a non-transitory storage media (not shown in figures) and the mentioned development board 300. The non-transitory storage media stores a plurality of description codes. The non-transitory storage media is configured to execute the method for implementing the online integrated microcontroller development tool via the online integrated microcontroller development tool system 200.


Additionally, in an embodiment of the present disclosure, when the client connects the development board 300 online to test the microcontroller application circuit, in order to ensure that the development board 300 of the client is consistent with description codes, a driver, etc. stored in the non-transitory storage media, the codes comprise a verification program to verify the development board 300. After the development board 300 is verified, the computer device 100 is allowed to communicate with the online integrated microcontroller development tool system 200 to perform subsequent testing of the microcontroller application circuit.


However, the hardware description compiled code generated above is an idealized case. In the practical test, the test results may not meet the client's expectations, because, for example, the circuit routings are too close (may cause inductive coupling), clock of the function implementation is not synchronous, or the specification of the microcontroller do not meet the requirements, etc. Therefore, by testing, the client is able to understand whether the data output by the developed microcontroller meets the expectations, especially for the power consumption, performance (accuracy) and area test. The client can re-select the suitable model number which is more in line with the actual requirement. Then, the pin required module 210 re-arranges the pins according to the pin requirement information, and regenerate the application circuit to implement the microcontroller application circuit, or to optimize the microcontroller application circuit.


Further, taking a second example, refer to FIG. 4, which is schematic diagram of a second example of a pin requirement information and a functional component of a microcontroller of the online integrated microcontroller development tool system 200 according to an embodiment of the present disclosure. If the client wants to make a microcontroller with gravity sensing, the functions required by the client are a communication module communicated with the computer device 100 by means of WiFi or Bluetooth, a gravity sensor (G-sensor), a function of a universal serial bus (USB) for charging or transmitting data to the computer device, as well as a function to connect a display screen.


Therefore, the client selects the specification as Flash 256 Kb in the online integrated microcontroller development tool system 200. As shown in Table 2 below, the microcontroller block at least has pins such as UART pins, I2C pins, SPI pins, USB pins and so on.

As shown in FIG. 4, after the pin required module 210 confirms the pin requirement information input by the client, the pin required module 210 starts to select the suitable model number (eg, MCU-1000, but the present invention is not limited to this model number) from the database 220. Then, the pin required module 210 performs the pin arrangement on the microcontroller block of the microcontroller (MCU-1000). The functional component module 230 selects an appropriate communication module 410, a G-sensor 420, a display screen module 430, an electrically-erasable programmable read-only memory 440 (EEPROM) and other functional components, and the functional component module 230 generates the corresponding circuit structure.


As shown in FIG. 4, the 9th and 10th pins are the pins of the VC, and the 9th and 10th pins are connected to the EEPROM 440 to store all information for a certain period of time. The 13th and 14th pins are the UART pins, and the 13th and 14th pins are connected with the communication module 410 (for example, a WiFi module or a Bluetooth module). The 17th and the 18th pins are the VC pins, and the 17th and the 18th pins are connected to the display screen module 430. The 41st to 44th pins are the SPI pins, and the 41st to 44th pins are connected to the G-sensor 420. Besides, the 33rd to 36th pins are the USB pins which are utilized for charging and transmitting data.


Based on the above, the circuit structure is generated by the functional component module 230, and the description code project output module 240 generates the microcontroller application circuit hardware description code based on the circuit structure. Next, the test circuit project output module 250 forms and outputs the test circuit hardware description code. Then, the online program development-compilation module 260 generates the hardware description compiled code, so that the microcontroller can execute the functions of sensing the gravity and presenting the data on the display screen.


Next, the hardware description compiled code generated by the online program development-compilation module 260 can be provided to the client to download to the development board 300 for testing. The application circuit of the microcontroller (MCU-1000) can be tested after the development board 300 of the client is connected to the computer device 100 and verified successfully.


Moreover, the microcontroller (MCU-1000) may be configured in devices such as a pedometer, a dashcam, or exercise intensity detectors. Although the devices are related to the application circuits of the G-sensor, the accuracy requirements of the G-sensor for corresponding devices are different from each other. For instance, the accuracy requirement of the dashcam is higher than that of the pedometer, and the accuracy requirement is related to the data processing capability, filtering out noise and so on of the microcontroller. As a result, different accuracy of the G-sensor has different application circuit structure. Thus, after the hardware description compiled code is tested on the development board 300, it may happen that the selected suitable model number does not meet the client's expecting accuracy requirements due to the different bit requirements of the analog-to-digital converter, and the appropriate model number is re-selected.


As the stated as above, the circuit structure is an important part of developing microcontroller. As the mentioned two examples, if the circuit structure of the second example involves the amplification and filtering of the gravity signal to improve the accuracy of the gravity signal, and the hardware description compiled code must be able to control peripheral units (such as the screen display), the circuit structure involved in the second example becomes rather complicated. The online integrated microcontroller development tool system of the present disclosure can provide the clients with examples of the circuit structures, so that the clients do not need to design circuits from scratch by themselves. Moreover, the clients can modify the existing examples of the circuit structures online, so as to develop microcontrollers that meet the needs of the applications.


Furthermore, for the clients, the clients do not need to install any software, and the online platform can generate microcontrollers for different applications based on the client's own needs. Also, various circuit hardware description codes can be automatically generated, and the circuit hardware description codes can be tested with the development board. In this way, the clients can obtain related product resources simultaneously, so as to achieve the technical effects of speeding up the development process and reducing development cost. Moreover, the client's inputs and operations in the online platform are not complicated, so that a platform for diversified learning and development of microcontrollers is provided.


In addition, for developers who develop microcontrollers, because of the inputs and operations from other clients in the online integrated microcontroller development tool system, customer information and market requirements can be obtained. In this way, the embodiments of the present disclosure can provide developers with the planning direction of future products. Moreover, better digital services, more cost-effective products, etc. are provided. Therefore, the present disclosure has huge commercial value.


It should be understood that the examples and the embodiments described herein are for illustrative purpose only, and various modifications or changes in view of them will be suggested to those skilled in the art, and will be included in the spirit and scope of the application and the appendix with the scope of the claims.
