CircuitPython Documentation

repository·main·Indexed 26 days ago

https://github.com/adafruit/circuitpython

A beginner-friendly, open-source version of Python optimized for microcontrollers, focusing on ease of use via USB/BLE connectivity. This documentation covers building the firmware, using the mpy-cross compiler to generate .mpy bytecode, and port-specific instructions for hardware such as the AD-APARD32690-SL, Spresense (CXD56), and NXP i.MX RT10xx series. It also includes details on libraries like AnimatedGIF and littlefs.

What's inside CircuitPython

  2. Overview of AD-APARD32690-SL

    main

    The AD-APARD32690-SL is a CircuitPython port for a board featuring the MAX32690, a dual-core ARM Cortex-M4/RISC-V MCU with 3MiB Flash and 1MiB SRAM.

    Hardware Features:

    • Form-factor similar to Arduino Mega (supports Arduino-style shields).
    • Two Pmod connectors: P8 (SPI) and P13 (I2C).
    • Supports 10BASE-T1L Ethernet, Wifi, Bluetooth, USB, and Security via MAXQ1065.

    Current CircuitPython Limitations:

    • Most advanced features (Ethernet, Wifi, Bluetooth, Security) are not yet available.
    • USB support is planned for a future update; other features are currently unplanned.

  4. Overview of Makerdiary nRF52840 Connect Kit

    main

    The Makerdiary nRF52840 Connect Kit is an open-source prototyping kit based on the nRF52840 SoC. It supports various wireless protocols including Bluetooth LE, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT, and 2.4 GHz proprietary stacks.

    Key hardware features include:

    • Peripherals: USB 2.0, NFC-A, GPIO, UART, SPI, TWI, PDM, I2S, QSPI, PWM, ADC, and QDEC.
    • GPIO: Up to 32 multi-function GPIO pins (7 of which support ADC).
    • Storage/Display: External 64 Mbit QSPI flash and an RGB LED.
    • Connectivity: USB-C interface, Chip antenna or U.FL receptacle options, and a Serial Wire Debug (SWD) port.
    • Power: Flexible management for USB-C, external supplies, or batteries.

  8. Overview of Makerdiary iMX RT1011 Nano Kit hardware

    main

    The Makerdiary iMX RT1011 Nano Kit is a prototyping kit based on the NXP iMX RT1011 Crossover MCU (Arm Cortex-M7 core, up to 500 MHz).

    Key Hardware Features:

    • Memory: 128 KB on-chip RAM (configurable as TCM or general-purpose) and external 128 Mbit QSPI flash with XIP support.
    • Peripherals: High speed USB, UART, SPI, I2C, SAI, PWM, GPIO, ADC, etc.
    • I/O: Dual-row 40 pins (DIP/SMT type) providing up to 33 multi-function GPIO pins (including 15 configurable ADC inputs).
    • Connectivity: USB-C and Serial Wire Debug (SWD) port.
    • User Interface: Programmable LED and Button.

  9. Overview of Makerdiary nRF52840 M.2 Developer Kit

    main

    The Makerdiary nRF52840 M.2 Developer Kit is an IoT prototyping platform consisting of an nRF52840 M.2 Module and an M.2 Dock. It is designed for prototyping IoT products with a path to scale to production by using the nRF52840 M.2 Module with custom PCB hardware.

    For hardware-specific details, refer to the official Makerdiary repository: https://github.com/makerdiary/nrf52840-m2-devkit

  10. Understand Core Module availability in CircuitPython

    main

    CircuitPython core modules are designed to be consistent across different ports and boards. However, a module may be missing from a specific board if:

    1. The underlying hardware does not support the feature (e.g., a microcontroller without analog features will not have analogio).
    2. Flash memory space is too limited to include the module.

    To verify if a specific module is available on your hardware, consult the support_matrix documentation.
