micropython-samples

A place for assorted code ideas for MicroPython. Most are targeted at the Pyboard variants.

mutex

A class providing mutal exclusion enabling interrupt handlers and the main program to access shared data in a manner which ensures data integrity.

watchdog

Access the simpler of the Pyboard's watchdog timers.

reverse

Fast reverse a bytearray.

font

Convert a C file produced by GLCD Font Creator to Python for storage as persistent byte code.

ds3231_pb

Driver for the DS3231 low cost precison RTC, including a facility to calibrate the Pyboard's RTC from the DS3231.

Buildcheck

Raise an exception if a firmware build is earlier than a given date.

timed_function

Time a function's execution using a decorator

fastbuild - Pyboard use under Linux

Build MicroPython with your frozen bytecode, put the Pyboard into DFU mode, and deploy the build to the board with a single command. Takes just over 60 seconds on a fast PC. Note the use of make's j argument to use mutliple cores. Empirically 8 gave the fastest build on my core i7 4/8 core laptop: adjust to suit your PC.

Includes udev rules to avoid jumps from /dev/ttyACM0 to /dev/ttyACM1: ensures Pyboards of all types appear as /dev/pyboard. Also rules for USB connected WiPy and FTDI USB/serial adaptor.

ESP8266

benchmark.py Tests the performance of MQTT by periodically publishing while subscribed to the same topic. Measures the round-trip delay. Adapt to suit your server address and desired QOS (quality of service, 0 and 1 are supported). After 100 messages reports maximum and minimum delays.
