Before getting to know about the MAIX product series, it is very necessary to understand the MaixPy project. It can help you quickly use the Al module. MaixPy is a project of porting Micropython to K210 chip (running Micropython parser on K210), that is, users can finally control the function of K210 chip through Micropython programming. For example, you can directly call the facial recognition algorithm built into the firmware through Micropython programming, and finally generate a Micropython file, which can be downloaded to the Flash chip, and run on it. In addition, MaixPy supports the normal operation of MCU and integrates machine vision and microphone arrays to rapidly develop intelligent applications in the field of AIoT with extremely low cost and practicality. What is the Development Environment on MaixCube? By default, the development board has burned MaixPy firmware (the firmware source code is open source and can be downloaded from GitHub). MaixPy has developed a variety of functional libraries that developers can call directly. Maix series products use Maix IDE developed by the Sipeed team. The software is free of installation. After downloading, you can directly use MaixPy to use Micropython script syntax. Developers can edit the script on the computer and upload it to the development board to execute the script directly on the development board. The IDE can view camera images in real time and save files to the development board, which is very convenient for development. In addition to MaixPyIDE, developers can also use ArduinoIDE, PIatformIO IDE, and other environments for development. Please refer to our technical information for details.
