The following short Python programs will demonstrate essential operation of the Raspberry Pi Pico board. These assume one or more I2C (or I2C) devices are externally attached. The I2C bus is a two-wire bidirectional serial bus for short-distance low-bandwidth communication between a microcontroller and peripherals. Each sample can be run by copying the program into code.py on …
The following short Python programs will demonstrate essential operation of the Raspberry Pi Pico board. These assume one or more hobby servo actuators are externally attached. Each can be run by copying the program into code.py on the CIRCUITPY drive offered by the board. The text can be pasted directly from this page, or each file can …
