prototyping

Some prototyping with microboards à la Arduino, ESP8266 and Raspberry PI. Exploring and investigating the integration with Mosquitto MQTT broker and Home Assistant.

modules

Periodics

• Purpose
  manages an array of interval periods to support the execution of recurrent events on a regular, polled basis. Application: Arduino and alikes.

• Use case
  Want to be able to execute various functions at different intervals - without the use of timer(s) and associated interrupt(s). E.g. you want to poll an NTP server every 10 minutes, while reading a sensor every 30 seconds. And you don't want to jeopardize the Wifi servicing functionality of the Wifi module (ESP8266).

roundRobin

• Purpose
  This class manages a series of records (structures), round robin wise:

  • new records are added up until the entire buffer is in use
  • after which space is being reused, on a FIFO basis.

• Application
  Keeping a datalogger in memory - e.g. sensor values.
