This README provides a quick overview of QP for Arduino. Please refer to the companion webiste to this project at:
https://www.state-machine.com/arduino
The QP adaptation for Arduino is distributed in a single ZIP
archive qp-<ver>_arduino-1.8.x.zip, where <ver> stands for
the version of the QP frameworks.
You need to unzip the qp-<ver>_arduino-1.8.x.zip archive into your
Arduino <Sketchbook> folder. To find out where your <Sketchbook> folder
is, or to configure a different location for your <Sketchbook> folder,
you need to open the Arduino IDE and select File|Preferences menu.
The Sketchbook location will be shown at the top of the Preferences
dialog box. Once you identify the <Sketchbook> folder, you simply unzip
the whole qp-<ver>_arduino-1.8.x.zip archive to this folder.
The archive qp-<ver>_arduino-1.8.x.zip contains two external libraries
for SAM-based Arduinos:
qpcpp_arm-cm-- QP/C++ framework for Arduinos based on ARM Cortex-Mqpn_avr-- QP-nano framework for Arduinos based on AVR
NOTE:
qpn_avris now obsolete. It is provided for backwards compatibility only!
The archive also contains the QM modeling tool for Windows
qm-- QM modeling tool for Windows 32/64-bit
After the installation, your Arduino <Sketchbook> folder should look
as follows:

NOTE: The QP-Arduino archive contains QM for Windows only. But QM is also available for Linux and MacOS hosts. If you wish to work on those operating systems, you will need to install QM separately, as described at: https://www.state-machine.com/qm/gs.html
Assumming that you have installed the QP library in your <Sketchbook>
folder, the examples provided in each QP library show up in the Arduino
IDE under the menu:
File|Examples|Examples from Custom Libraries
The intended way of working with the examples is to use the
QM modeling tool to modify
the models (.qm files) and then to generate code from these
models. In this scenario, the Arduino IDE is used only to build and
upload the code to the Arduino board(s).
NOTE: The preferences in the Arduino IDE should be set up to Use external editor so that the IDE will update the code each time it is re-generated by the QM modeling tool.
Each example model has documentation, which you can view in the QM tool. The model documentation shows in the Property Editor when the model item is active.
The qpcpp_arm-cm library now supports the QP/Spy software tracing. This feature is also demonstrated in the qpcpp examples (with the BSP).
To activate the software tracing, you would need to un-comment the QS_ON
macro at the top of bsp.cpp source file.
NOTE: Because the QP/Spy output is binary, you cannot watch it with a standard serial terminal. Instead, you need to use the QSPY host utility.
Once QP/Spy tracing is enabled, this communication with the target system can be used to for QView visualization and monitoring
The dpp_bsp-sam example demonstrates the [QView monitoring]. To see this
feature, you need to upload the dpp_bsp-sam code to the Arduino UNO board and
then you need to launch QView, from the sub-directory qview in the
dpp_bsp-sam example.
The QP/C++ real-time embedded framework (RTEF) for Arduino are licensed under the modified GPLv3 license with the QP-Arduino Exception (see also the file QP-Arduino_GPL_Exception.txt in the root of the archive).
Specifically, the Arduino GPLv3 Exception removes the requirement to expose your proprietary source code as long as you deploy it on an Arduino-Certified board.
The QM model-based design tool is freeware. The QM tool is provided under the terms of a simple End-User License Agreement (EULA).
