A Matter Wi-Fi Light Bulb in Rust on the Raspberry Pi Pico 2 W

This repository contains examples for the Raspberry Pi Pico 2 (RP2350) board, written in Rust using the Embassy async framework. cargo generate --git https://github.com/ImplFerris/pico2-template.git --name rust-rpico2-embassy-examples Hardware Board: Raspberry Pi Pico 2 I2C pins: I2C0 SDA: GPIO4 I2C0 SCL: GPIO5 I2C1 SDA: GPIO2 I2C1 SCL: GPIO3 UART pins: UART0 TX: GPIO0, UART0 RX: GPIO1 UART1 TX: GPIO8, UART1 RX: GPIO9 Examples I2C Examples hs3003_i2c Reads temperature and humidity from an HS3003 sensor using the Embassy async framework. cargo run --example hs3003_i2c Wiring (Arduino Modulino Thermo): Modulino -> RPi Pico 2 ---------- -------------- GND (black) -> GND VCC (red) -> 3.3V SCL (yellow)-> GPIO5 (Pin 7) (I2C0 SCL) SDA (blue) -> GPIO4 (Pin 6) (I2C0 SDA) About HS3003: The Renesas HS3003 is a high-performance temperature and humidity sensor: Reads accelerometer data from an ADXL345 sensor over I2C0 using Embassy. ADXL345 -> RPi Pico 2 ---------- -------------- GND (black) -> GND VCC (red) -> 3.3V SCL (yellow)-> GPIO5 (Pin 7) (I2C0 SCL) SDA (blue) -> GPIO4 (Pin 6) (I2C0 SDA) About ADXL345: The ADXL345 is a small, thin, low power, 3-axis accelerometer with high resolution (13-bit) measurement at up to ±16 g. Digital output data is formatted as 16-bit twos complement and is accessible through either an SPI (3- or 4-wire) or I2C digital interface. zermatt Displays a 320x240 image of Zermatt on the Adafruit 2.2" TFT LCD display in landscape mode. cargo run --example zermatt Wiring (Eye-SPI Breakout): Raspberry Pi Pico 2 Eye-SPI Breakout +-----------------------+ +---------------------------+ | | | | | 3V3 (Pin 36) --------+------+-> VIN (Red Wire) | | GND (Pin 38) --------+------+-> GND (Black Wire) | | GPIO18 (Pin 24) -----+------+-> SCK (Blue Wire) | | GPIO19 (Pin 25) -----+------+-> MOSI (Green Wire) | | GPIO16 (Pin 21) -----+------+-> MISO (Yellow Wire) | | GPIO20 (Pin 26) -----+------+-> DC (White Wire) | | GPIO21 (Pin 27) -----+------+-> RST (Orange Wire) | | GPIO17 (Pin 22) -----+------+-> TCS (Blue Wire) | | | | | +-----------------------+ +---------------------------+ zermatt_snow Displays a 320x240 image of Zermatt on the Adafruit 2.2" TFT LCD display with animated falling snow, utilizing a physics engine and the Embassy async framework to draw to an off-screen lcd-async framebuffer and dispatch via DMA without blocking the CPU. cargo run --example zermatt_snow Wiring is identical to the zermatt example. ds18b20 Reads temperature from a DS18B20 waterproof temperature sensor probe over a 1-Wire bus using Embassy. It utilizes a custom, cycle-accurate PreciseDelay implementation to achieve jitter-free sub-microsecond timing required by the 1-Wire protocol on the RP2350's Cortex-M33 core. cargo run --example ds18b20 Wiring Schematic: Raspberry Pi Pico 2 +-----------------------+ | | | [ ] 1 40 [ ] USB | | [ ] 2 39 [ ] | | [ ] 3 38 [G]ND --+-------+ (black) | [ ] 4 37 [ ] | | | [ ] 5 36 [3]V3 --+---+ | | ... ... | | | | [ ] 20 21 [ ] ----+---+---|---+ (white, GPIO16) +-----------------------+ | | | | | | | | | +-----------------------------+ | | | | DS18B20 Sensor / Probe | | | | | (Bottom/Flat Side) | | | | | | | | | | [GND] [DAT] [VCC] | | | | +-------|-------|-------|-----+ | | | | | | | | | | +-------+--[5K1]----+ | (Pull-Up Resistor | | | Resistor | between DAT & VCC) | | +---------------+ (red) +-------|-----------------------+ (black) | +--------------------------- (white) Breadboard Layout: The DS18B20 is a 1-Wire digital thermometer that provides 9-bit to 12-bit Celsius temperature measurements. It communicates over a 1-Wire bus, requiring only one data line (and ground) to interface with the microcontroller. It has a temperature range of -55°C to +125°C with ±0.5°C accuracy from -10°C to +85°C. Reads temperature and humidity from a DHT11 sensor using the Embassy async framework. It utilizes the async API of the dht-sensor crate combined with our cycle-accurate PreciseDelay implementation. cargo run --example dht11 --release Note: Due to timing sensitivity of the DHT11 protocol during the bit-read phase, you must run this example in release mode. Raspberry Pi Pico 2 DHT11 Module +---------------------+ +---------------------+ | | | | | GND (Pin 38) -------+----->| GND | | 3V3 (Pin 36) -------+----->| VCC | | GPIO16 (Pin 21) ----+----->| DAT (Data) | | | | | +---------------------+ +---------------------+ Important The DHT11 is a basic, ultra low-cost digital temperature and humidity sensor. It uses a capacitive humidity sensor and a thermistor to measure the surrounding air, and spits out a digital signal on the data pin (no analog input pins needed). It has a temperature range of 0°C to 50°C (±2°C accuracy) and humidity range of 20% to 90% RH (±5% accuracy). matter_wifi_light Implements a Matter-compatible Wi-Fi light bulb using the rs-matter stack. It uses BLE for commissioning and Wi-Fi for network connectivity, allowing you to add the Pico 2 W directly into Apple Hom
