About pikasTech/PikaPython

PikaPython is an ultra-lightweight Python interpreter designed for embedded systems, capable of running with only 4KB of RAM and zero dependencies. It supports out-of-the-box use with no configuration required and is easy to extend using C. A unique pre-compiler automatically generates Python module bindings from .pyi files, enabling rapid development. The project includes an online project generator, a serial terminal and package management tool (PikaPython Studio), simulation capabilities, and support for a wide range of MCUs including STM32, Air32, CH582, and others. PikaPython also offers a package manager and community documentation, making it suitable for IoT, prototyping, and educational applications on resource-constrained devices.

FAQ

What is PikaPython?
PikaPython is an ultra-lightweight Python interpreter designed for embedded systems, with only 4KB RAM requirement and zero dependencies. It allows easy extension with C and is ready to use out of the box.
How does PikaPython bind C functions to Python?
PikaPython uses a pre-compiler written in Rust. Developers write Python API stubs in .pyi files, and the pre-compiler automatically generates the C bindings.
What microcontrollers are supported?
PikaPython supports many MCUs including STM32 (G0, F1, F4, H7, etc.), Air32, CH582, CH32V103, BL-602, and others. See the BSP folder in the repository for details.
Is PikaPython free to use?
Yes, PikaPython is open source and free. A Community Edition license is required for building Keil projects, which is currently free.
What tools are available for PikaPython?
PikaPython offers an online project generator, PikaPython Studio (serial terminal and package manager), and simulation projects for development without hardware.
