Task Manager Low Power example for SAMD boards
There are often cases when you'll need to run a micro controller from a battery power source. Unlike when running from mains power, every milli-amp matters. In these cases IoAbstraction's task manager is able to integrate easily with most low power libraries. Task manager works by repeatedly calling the function within or , during each loop task manager evaluates...
LiquidCystalIO with MCP32017 I2C or any other arrangement
You can connect up a device using just about any arrangement of pins or expander, at the end of the day any device supported by IoAbstraction, including MultiIo (pins and IoExpander mix) can be used here. Examples showing these use cases MCP23017 LiquidCrystal example Shift register 74HC595 LiquidCrystal Back to the main page
Programming Arduino using tasks instead of loops - tutorial
In this tutorial for TaskManagerIO I explain the differences between traditional loop based programming; which is very common on the Arduino platform and event based programming based on taskManager. Although event based programming looks slightly more complicated at first, as the sketch and surrounding code gets more complex, eventing will scale to that much easier. Eventing task frameworks make ongoing maintenance...
Liquid Crystal fork example using IO Abstraction library - examples
Recently, I have made a fork of Arduino LiquidCrystal (HD44780 display driver library) that allows the library to work with the IO abstraction library, meaning you can configure a display to use Arduino pins, an i2c 8574 IO expander or shift registers by simply changing one line of code in your sketch. There are two additional examples provided with this version...
LiquidCystalIO with PicoSDK/mbed/NativeCpp over i2c or pins
LiquidCrystalIO is now also compatible with PicoSDK and mbed boards. It supports regular mbed pins, I2C backpacks based on PCF8574 and MCP23017 based connections. You can adapt any of the Arduino examples for mbed very easily, as the API is 99% the same. The most recent examples for this are in our native C++ CMake project in https://github.com/TcMenu/tcLibraryDev Back to the...
Working with Menu Item types in tcMenu
Many embedded applications need to present status and allow users to manage settings. TcMenu provides first class support for both presenting status and managing configuration/settings using menu items. It is possible to use with and without a local user interface. All menu item types can be accessed remotely, and we have a remote API, UI solutions, and connectors to commercial IoT...
PGA2310 Volume Control device for IoAbstraction
PGA2310 Volume Control device Provides a simple analog device that can be used to control a PGA2310 volume device. Left channel is 0 and right channel is 1. The device should be connected on the SPI bus as usual. This should work with Arduino now, and mbed in a patch release coming soon. To use first include the header: Then initialise...
Arduino logging using io-logging
Logging is part of the TcMenu offering provided by library , it has a moderately complete logging framework that is still lightweight enough to work on small boards. It can easily be turned off completely for very small boards too. TaskManagerIO, IoAbstraction and tcMenu use this logging to provide information about internal state and operations. You can also use this logging...
Task Manager - Spin Lock guide
Task Manager supports the concept of Spin Locks to protect sensitive asynchronous operations from becoming interleaved. For example, to protect sensitive blocks of code. Be very aware that this does not include a memory barrier. A spin lock loops waiting for the lock to become available, you can either spin for a period of time, or until the lock is...
