A collection of Python modules and examples for MicroPython, targeted mainly at STM32F4-based boards, like the STM32F4DISCOVERY board or the original pyboard. Most modules also work on the MicroPython unix port or even other bare-metal ports, e.g. the esp8266 or esp32 port.

Currently, this collection contains:

• accel - a fixed version of staccel.py from the main MicroPython repo including examples.
• encoder - a library for reading a rotary encoder connected to two digital input pins, including examples. Features gray code error checking, making software or hardware debouncing uneccessary in most cases.
• lcd - a library for interfacing with a HD44780-compatible LCD controller, including examples.
• midi - a library for receiving and sending MIDI data via the UARTs or the USB virtual serial interface, including examples.
• mrequests - an evolution of urequests from micropython-lib with improvements and new features.
• netconfig - simple WiFi or ethernet network setup from JSON configuration files.
• picoredis - a very mimimal Redis client library (not only) for MicroPython.
• spiflash - a module for using Winbond W25Q* SPI-attached flash memory chips with MicroPython (adapted from code found in this repo).
• spimaster - a rudimentary library to communicate via SPI with an ESP826 module as the SPI slave, which runs an Arduino sketch using the SPISlave library.
• untar - a very simple module to unpack an uncompressed tar archive, using the utarfile module from micropython-lib.
