#Arduino libraries raspberry pi how to

Whenever you include IoAbstraction.h or include PlatformDetermination.h directly, then IoAbstraction need to work out how to provide all input output features that it supports. TM_ENABLE_CAPTURED_LAMBDAS redefine task manager callback functions as std::function on boards that support it, therefore allowing argument capture.DEFAULT_TASK_BLOCKS - sets the number of timesd task manager can allocate a block of size DEFAULT_TASK_SIZE.DEFAULT_TASK_SIZE - sets the number of tasks in each block, if you define this you MUST define DEFAULT_TASK_BLOCKS too.The follow build flags can be set either in your build tool or in zio_local_definitions.h: You should only ever call runLoop from a single thread, usually for the default taskManager instance that would be the loop() method on Arduino, or main() on mbed. Again the thread safety is so that you can put events into task manager from any thread, or trigger events from interrupts. Whenever you include TaskManagerIO.h this pulls in TaskPlatformDeps.h to work out what platform you’re building for, and to create suitable thread safety and CAS or Atomic based locking constructs for that platform. This means that you can easily define build options when using Arduino 1.x IDE. This allows two ways of setting build level flags, firstly by providing them in the build options, secondly within this file. Most of our libraries support adding a file locally in the root of your source called zio_local_definitions.h, once added this will be included by the platform determination before doing anything else. Completed for CircularBuffer but not TaskManager.ĭefining Build Flags and Platform settings On STM32Duino at the moment we are transitioning from using Arduino Atomic functions to using direct LDREX/STREX calls.On Raspberry PI pico earlephilhower core, circular buffers and task manager use a critical section to synchronize data.On ESP boards we call yield more often within the run loop to prevent watchdog resets.For ESP32 we use the underlying CAS capabilities to ensure cross core locking.We’ve tested on a few different Arduino mbed and direct mbed boards.

For both mbed direct and Arduino that’s based on mbed we rely on mbed inbuilt CAS locking.

What boards do our libraries support? ProcessorĪlthough we only test on some Arduino mbed boards, it should work on nearly all that we know of, you can take a look at the list of mbed boards we check for here, if another springs to light that we haven’t added please try adding it to that define statement, and if it works let us know. We test with everything from Uno to ESP32 and large STM32F4 boards. The above libraries support a wide range of hardware, including nearly every official Arduino board, most ESP boards, along with many mbed version 5 and 6 boards with or without an RTOS.

LiquidCrystalIO a task manager friendly fork of the Arduino LCD library that works over many IO devices.

SimpleCollections a simple binary searchable list and a thread/interrupt safe circular buffer that work on a very wide range of boards.

tcUnicodeHelper UTF-8 unicode support for Adafruit_GFX, tcMenu, U8G2, LTDC, and TFT_eSPI.

tcMenu a fully fledged embedded menu framework with a designer UI and IoT capabilities.

IoAbstraction provides user input, EEPROM and IO helper classes.TaskManagerIO provides core event and task scheduling services to Arduino sketches.There are several core libraries that we keep in lock step in terms of compatibility and board support.
