Pi Pico Puts Bluetooth Keyboards on the I2C Bus
A project called bt2i2c uses a Pi Pico W microcontroller to connect Bluetooth keyboards to an I2C bus, allowing keystrokes to be transmitted over I2C as if coming from a standard BlackBerry keyboard. This setup simplifies integrating Bluetooth input devices into microcontroller projects by leveraging existing I2C code and hardware. The development highlights the growing capability of microcontrollers to handle complex tasks traditionally managed by computers, offering new possibilities for embedded systems and peripheral integration.
A Pi Pico W microcontroller can now connect to Bluetooth keyboards and send keystrokes over the I2C bus, making it easier to use standard keyboards with embedded systems.
This development simplifies input handling for microcontroller projects, enabling more flexible and user-friendly interfaces for devices like custom terminals or IoT gadgets.
It highlights how open-source innovation can make complex hardware interactions more accessible, encouraging experimentation and practical applications in everyday tech.
