[0046] Although the programmable microchips in the prior art have realized the basic functions of intelligent control to a certain extent, such as obtaining basic attribute information such as acceleration, direction and temperature through the built-in sensor module, their functional limitations are significant and it is difficult to fully adapt to the complex and changing application scenario requirements. In order to overcome this limitation, the embodiments of the present invention adopt an expandable pin module design, which not only greatly enriches the interface capabilities of the chip, but also provides users with unprecedented flexibility and compatibility.

[0047] Specifically, through this pin module, the programmable microchip can easily connect to a variety of advanced sensor modules, including but not limited to:

[0048] Ultrasonic sensor modules are used to accurately measure distances and realize functions such as object positioning and obstacle avoidance navigation. They show great potential in the fields of robotics and autonomous driving.

[0049] Touch or tilt sensor modules that can detect physical contact or changes in tilt angle, suitable for smart home control, game interaction and health monitoring devices.

[0050] Color recognition sensors provide intelligent solutions for fields such as machine vision, artwork analysis, and food quality control by identifying color information.

[0051] Tracking sensors, specially designed to follow a predetermined path, are core components of automated equipment such as automatic navigation vehicles and logistics robots.

[0052] Infrared obstacle avoidance sensor uses infrared technology to achieve non-contact obstacle detection, enhancing the safety and stability of equipment in complex environments.

[0053] Flame or light sensors are sensitive to flame or light intensity in the environment and are suitable for fire warning, lighting control, photosynthesis research, etc.

[0054] Sound sensors capture and analyze sound signals, providing key data for speech recognition, environmental noise monitoring and security systems.

[0055] Combustible gas sensors detect the concentration of combustible gases in the air and are important tools for industrial safety and home protection.

[0056] Humidity sensors accurately measure ambient humidity, which is crucial for agricultural irrigation, warehouse management, indoor climate control, etc.

[0057] It lays a solid foundation for realizing the seamless connection between programmable microchips and the Internet of Things. Through wireless transmission modules (such as Wi-Fi, Bluetooth, etc.), the chip can transmit sensor data to the cloud platform in real time to achieve remote monitoring, data analysis and intelligent decision-making, thereby enabling smart cities, smart manufacturing, smart agriculture and other fields, and promoting the widespread application and in-depth development of Internet of Things technology. This application not only significantly improves the functionality and applicability of programmable microchips by introducing highly scalable pin modules and supporting a variety of external sensors, but also provides strong technical support for its integration into the Internet of Things ecosystem and opening a new chapter of the Internet of Everything.

[0058] The wireless transmission module is used to realize the wireless communication function; the wireless transmission module includes a Bluetooth module and a wireless module;

[0059] The Bluetooth module uses the Nordic nRF51822 low-power Bluetooth chip;

[0060] The wireless module uses 2.4G wireless technology to achieve automatic frequency scanning when powered on.

[0061] The wireless transmission module is designed to provide a stable, efficient and low-power wireless communication solution to meet the needs of the growing Internet of Things (IoT) and smart device market. The wireless transmission module integrates a Bluetooth module and a wireless module, which work together to provide users with a variety of wireless communication options. The module not only supports short-distance data transmission, such as Bluetooth connection, but also has a wider range of wireless communication capabilities, suitable for different application scenarios and needs.

[0062] The Bluetooth module uses the Nordic nRF51822 low-power Bluetooth chip. This Bluetooth chip has low power consumption performance, powerful processing capabilities and flexible configuration options. It supports the Bluetooth 4.0 (also known as Bluetooth Smart or BLE) standard, which can maximize the battery life of the device while ensuring the quality of data transmission.

[0063] At the same time, the nRF51822 chip provides a wealth of peripheral interfaces, including UART, SPI, I2C, etc., which facilitates connection and data exchange with other parts of the micro-programmable chip. In addition, it also has a built-in powerful 2.4GHz wireless transceiver that supports multiple Bluetooth operation modes such as broadcasting, scanning, connection and data transmission.

[0064] Low-power Bluetooth technology is widely used in smart wearable devices, smart homes, medical equipment, etc. Through the nRF51822 chip, the micro-programmable chip can easily establish connections with Bluetooth devices such as smartphones and tablets to achieve functions such as data synchronization and remote control.

[0065] The wireless module uses 2.4G wireless technology, which is a mature technology widely used in the field of wireless communication. It has the advantages of fast transmission speed, strong anti-interference ability and low cost.

[0066] In order to ensure the stability and reliability of wireless communication, the wireless module will automatically perform frequency scanning when it is turned on. This function can detect and avoid interference sources within the current frequency band and select the best communication channel for data transmission. This can not only improve the speed and quality of data transmission, but also effectively reduce packet loss and errors during communication.

[0067] 2.4G wireless technology has a longer transmission distance and strong wall penetration ability, which is suitable for scenarios where data needs to be transmitted across rooms or floors. In addition, this technology also supports simultaneous communication between multiple devices, making it possible to build complex IoT systems.

[0068] By integrating the Bluetooth module and the wireless module into the wireless transmission module of the micro-programmable chip, users can flexibly choose the wireless communication method that best suits the current application scenario. For example, in scenarios that require low power consumption and short-distance connections, you can choose to use the Bluetooth module; in scenarios that require longer transmission distances or cross-room communication, you can switch to the wireless module. This flexibility and diversity enables micro-programmable chips to be widely used in smart homes, industrial automation, medical equipment, smart wearables and other fields, injecting new vitality into the development of Internet of Things technology.

[0069] The vibration motor is used to generate vibration;

[0070] The buzzer is used to emit sounds of different decibels.

[0071] The micro intelligent programming chip supports Python, Scratch and JavaScript programming languages.

[0073] The micro intelligent programming chip adopts a pluggable structure.

[0074] A heat sink is attached to the back of the micro intelligent programming chip.

[0075] The corresponding OLED screen is replaced based on the size of the LED matrix screen. When designing a micro-programmable chip, a display solution based on an LED matrix screen is a common choice. It has been widely used in various embedded systems and smart devices due to its advantages such as high brightness, high contrast and good viewing angle. OLED is a screen with better color performance, lower power consumption and thinner volume than LED matrix screens.

[0076] Therefore, in a specific implementation of the present invention, the OLED screen replaces the LED matrix screen. First, the first step of the replacement is to determine the size of the LED matrix screen. Next, a suitable OLED screen can be selected based on these parameters. In the selection process, in addition to considering the size and resolution, it is also necessary to pay attention to factors such as the brightness, contrast, color saturation, viewing angle, power consumption and cost of the OLED screen. These factors will directly affect the performance of the OLED screen in a specific application scenario. After the physical replacement of the OLED screen is completed, software-level adaptation is also required. This includes adjusting the configuration of the display driver to ensure that the new OLED screen can correctly receive and display data from the micro-programmable chip. In addition, the display content may also need to be optimized to adapt to the color characteristics and resolution of the OLED screen. The embodiment of the present invention uses an OLED screen for display, which not only improves the display effect and user experience of the device, but also brings more possibilities and innovation space to the design of embedded systems and smart devices.

[0077] The embodiments of the present invention have the following beneficial effects:

[0078] Through the scalable pin module design, the chip's interface capabilities are greatly enriched, providing users with unprecedented flexibility and compatibility. This application not only significantly improves the functionality and applicability of programmable microchips by introducing highly scalable pin modules and supporting a variety of external sensors, but also provides strong technical support for its integration into the IoT ecosystem and opening a new chapter of the Internet of Everything. By integrating the Bluetooth module and the wireless module into the wireless transmission module of the micro-programmable chip, users can flexibly choose the wireless communication method that best suits the current application scenario.
