Raspberry Pi Pico as I2C Responder | Micropython, RP2040, RP2350 Andrea Favero 2025-03-08 | Micropython I2C communication with Raspberry Pi Pico as ResponderSetup:Controller:- Raspberry Pi Zero 2Responders: - Raspberry Pi Pico - RP2040-Zero - RP2350-ZeroConnections (for video recording only): - RPi Zero 2 connected via WiFi - Picos connected via USBData Transmission: - Data fields are encapsulated in dataframes with a checksum for validation at the receiver. - Structure: STX + Field1 + Field2 + ... + Checksum + ETX (with escape characters if needed). - Each transmission includes up to four 16-bit fields. - The responder returns an 8-bit response: 1 if the checksum is correct, 0 otherwise.I2C Bus: - 4.7kΩ pull-up resistors on SDA & SCL. - 470Ω series resistors on SDA & SCL (at Raspberry Pi Zero).Code & Examples: github.com/AndreaFavero71/i2c_pico_responderOne example demonstrates using one Pico as the Controller and others as Responders.
SENSORLESS homing of stepper motor| Micropython, Raspberry Pi Pico, PIO, TMC 2209, StallGuard Andrea Favero 2025-02-23 | Short demo showcasing MicroPython-based SENSORLESS homing & centering of a stepper motor. The control uses RP2040-Zero and PIO (Programmable Input/Output) combined with Trinamic TMC2209 driver.The StallGuard feature is used for homing detection, while the PIO's are used for steps counting and for stepper centering: The stepper is stopped in the middle of the 2 detected homes.Setup: - 1 NEMA 17 stepper motors. - 1 RP2040-Zero board. - 1 Trinamic TMC2209 driver. - the stepper is 200 pulses/rev, set to 1/8 microstep, therefore 1600 pulses/rev. - the stepper is controlled by the RP2040-Zero board, running MicroPython. - the range in between the hard-stops (homes) is varied along the video. - each time the push button is pressed, a new homing & centering cycle is started. - the stepper speed is alternated between 400Hz and 1200Hz.- UART comunication between RP2040 and TMC2209.This control method is part of a larger project, but it can be adapted for other applications requiring sensorless homing. Code & Examples: github.com/AndreaFavero71/stepper_sensorless_homingCode tested on RP2040-Zero, and it's expected to also work on RP2350-Zero (both having the RGB led onboard).
MicroPython Stepper Motor Control | RP2040, PIO & Raspberry Pi Demo Andrea Favero 2025-02-07 | Short demo showcasing MicroPython-based stepper motor control using RP2040-Zero and PIO (Programmable Input/Output).Steppers runs for a predefined number of steps, at speed (info sent to the PIO).Setup:• 3 NEMA 17 stepper motors.• Each motor is controlled by an RP2040-Zero board.• Commands (speed, direction, steps) sent via I2C, from a Raspberry Pi to the 3 RP2040-Zero boards.• Stepper class built on PIO for efficient step generation and accurate positioning.This control method is part of a larger project, but it can be adapted for other applications requiring precise stepper motor movement. Code & Examples: github.com/AndreaFavero71/pio_stepper_controlCode tested on Raspberry Pi Pico, Pico W, Pico 2, RP2040-Zero and RP2350-Zero.With RP2350 the accuracy extends to a broader range of steps frequency (info at GitHub).

Inverted pendulum Andrea Favero 2021-01-25 | Inverted pendulum, from an old A3 deskjet printer. Got inspired few years ago from a demostrator, at Cité des sciences et de l'industrie de Paris, and once the first Arduino board arrived in our home ... the project started :-) I tried to re-use as much as possible the printer's parts, and to make a clean design: All the signals to the car are integrated in the printer's ribbon, and the power supply is also from the printer.Control via Arduino Mega 2560 and LM298.Very good reference is the clip from kevin: youtube.com/watch?v=_kBZzQOslTc
