ATmega328PB Xplained Mini -- demo project for ATmega port. (#70)

Browse source 
* Bootstrap a demo from START. No driver is added in this commit.

* Add FreeRTOS source code to project. Remove unnecessary folder nesting.

Heap_4 is used here.

* Copy over main.c, FreeRTOSConfig.h, and regtest.{c, h}.

This commit compiles, but will need some work on timer used.

* This port has 2KB RAM. We are using 1KB for heap.

Further decreasing minimum stack size, and also use stack overflow check 1 to save some stack space.

* Preserve EEPROM set to false.

* End of the line.

* Reduce register test stack size.

32 8-bit register + 10 bytes for stack frame cost. Round up to 50.

* Adding Queue test in Integer test.

- g3 to easy debugging.
- mainCHECK_PERIOD is set to 1000 ticks. Note that this port for now use WDT as tick timer, and period is set to 15ms.
- vErrorChecks, is of highest priority. So if this task gets run before other tasks, the very first check will fail.

* Avoid false alarm.

Since we don't know in which order the tasks are scheduled, clearing any error for the first entry of vErrorChecks.

* ParTest.c to init, set, toggle onboard user LED at PB5.

* Added a task to blink onboard user LED.

Need a magic number for stack size.

Signed-off-by: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com>

* Explicitly setting timing slicing to 0.
This is to avoid unecessary context switch when multiple tasks are of the same priority.


Signed-off-by: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com>

* Add taskYIELD() at the end of the loop in each register test task.

This is to give other tasks of the same priority a chance to run, regardless of scheduling algorithm.

Signed-off-by: Yuhui Zheng <10982575+yuhui-zheng@users.noreply.github.com>

* minor, update comment in main.c.

\section doc_driver_mainpage_intro Introduction
AVR Code is a software library containing drivers, middleware and
applications for AVR microcontrollers. START, a web-based
GUI, is used to generate C-code according to the user's needs.
In START, the user selects the device for which to generate code.
Thereafter, the user selects the driver and middleware components
that he wants to include in the project. As an example, the user
may choose the device Tiny817, and add the USART and SPI driver.
The user can use START to configure the detailed behaviour of the
drivers, and configure the device's clock system and I/O pins.
Finally, the user exports the project as an atzip-file, which
can be opened in Studio or IAR Embedded Workbench. The
project contains:
- C and assembly files that can be compiled using the GCC
or IAR compilers.
- A directory with doxygen-files documenting the drivers included in the project.
The doxygen-files can be built into a HTML-document by executing the
command *doxygen doxyfile.doxygen* on a computer where doxygen is installed.
The file *doxyfile.doxygen* is found in the *doxygen/generator* directory in
the atzip-file.
- Example code documenting the usage of the configured drivers
\section doc_driver_mainpage_driver_overview Driver Overview
After the user has selected a device to configure, he will be able
to add and configure drivers and middleware available for that
device. In START, drivers are grouped by functionality, such as
SPI, USART or Timer. After adding desired functionality, such as
SPI, the user can configure the SPI function. This includes selecting:
- which hardware instance to use for implementing the functionality
- which driver to use for implementing the functionality
The devices may have several SPI hardware modules,
or may implement SPI functions through other hardware modules,
such as USART.
The combination of hardware and driver is given by the notation
Drivers:*Hardware*:*Driver_name*
where *Hardware* identifies the hardware the driver uses, and *Driver_name*
is the name of the driver. An example: *Drivers:TCB:Timeout* is the *Timeout*
driver running on an instance of timer TCB.
\section doc_driver_mainpage_configuring Configuring Drivers and Middleware
In general, functionality such as SPI is supported through multiple drivers.
Providing multiple drivers allows the user to select the flavor best suited to
his application: He may choose a simple but small SPI driver if this suits his
application, or a more complex but larger SPI driver if advanced SPI
functionality is needed.
In general, each peripheral has at least the following drivers:
- Init: Performs device initialization only, based on the
configuration the user selected in START. No API functions other
than init() is provided
- Basic : Basic functionality, provides an init-function and other
functions allowing the user to use basic functionality of the peripheral.
The Basic drivers are intended to cover functionality commonly found on
all hardware implementations, and are therefore very portable across
different devices. Typical examples of basic functions for an USART is to send
and receive bytes, either in polled or interrupt driven mode.
\section doc_driver_mainpage_usage Using the generated code
A project exported from START contains the drivers that the user
configured, along with a main.c-file that only initializes the drivers and
peripherals. The user will usually have to add code to main() in main.c
in order for the code to do something useful.
The example code in the examples directory can be used as a starting point in
order to learn how to use the drivers and their API. The examples are in the form
of functions that can be called directly from main().
The generated drivers may use interrupt requests to communicate with hardware.
The user code must normally enable global interrupts (using ENABLE_INTERRUPTS())
in order for these interrupts to be serviced. The drivers usually do not
enable global interrupts as part of their initialization.
\section doc_driver_mainpage_documentation Documentation of Drivers and Middleware
Drivers and middlewares are documented using Doxygen. Doxygen comments are
embedded into the exported C-code. In addition, exported projects have
a *doxygen* folder containing doxygen files with additional documentation.
The user must generate the doxygen documentation himself after exporting the
project. This is done by going to the *doxygen/generator* directory and
issuing the command *doxygen doxyfile.doxygen*. The doxygen application may need
to be installed on your computer, the installer can be found on the internet.
\subsection doc_driver_mainpage_documentation_user Documenting user code
The user can use doxygen to document his own code together with the code
generated by START. The file *doxygen/generator/doxyfile.doxygen* can
be modified to include the user's own code in the generated documentation.
Modify the tags *INPUT* and *FILE_PATTERNS* in the doxyfile to do this.
Refer to the doxygen manual for more information.
\section doc_driver_mainpage_output Generated Output
START exports projects as an <PROJECTNAME>.atzip file. This is a regular
zip-file which can be unzipped using standard unzip-tools. The contents
of the atzip-file is of course dependent on the configuration done in START.
Assume a typical project configured with PWM, SPI, TIMEOUT, TIMER and USART
drivers. Unzipping the atzip-file, or opening it in one of the supported
IDEs will reveal the following directory structure:
