*   - Embedded Wizard Studio V9.30
*   - Embedded Wizard Platform Package for NXP iMX_RT V9.30
*   - IMXRT1064-EVK Build Environment V9.30
*   - IMXRT1064-EVK development board
*   - MCUXpresso SDK V2.6.1
*   - GCC ARM Embedded Toolchain 8-2019-q3-update
*   - IAR Embedded Workbench 8.40.1, IAR C/C++ Compiler V8.40.1.212/W32 for ARM
*   - Keil MDK-ARM Professional Version 5.29.0.0, ARM Compiler 6.13.1 (armclang)
*   - MCUXpresso IDE V11.0.1 Build 2536
*

Getting started with IMXRT1064-EVK development board:
-----------------------------------------------------
  In order to get your first Embedded Wizard generated UI application up and
  running on your IMXRT1064-EVK target, we have prepared a detailed article,
  which covers all necessary steps.
  We highly recommend to study the following document:

  https://doc.embedded-wizard.de/getting-started-mimxrt1064-evk


Getting started with Embedded Wizard Studio:
--------------------------------------------
  In order to get familiar with Embedded Wizard Studio and the UI development
  work-flow, we highly recommend to study our online documentation:

  https://doc.embedded-wizard.de

  Furthermore, we have collected many 'Questions and Answers' covering
  typical Embedded Wizard programming aspects. Please visit our community:

  Please use this platform to drop your questions, answers and ideas.


/*******************************************************************************
* Important note:
* This Build Environment is intended to be used as template for Embedded Wizard
* GUI applications on the development board or your customer specific hardware.
* Please take care to adjust all timings and hardware configurations (e.g. system
* clock configurations, memory timings, MPU and cache settings) according to your
* needs and hardware capabilities in order to ensure a stable system.
* Please also take the hardware manufacturer's corresponding specifications,
* application notes and erratas into account.

Build Environment specific changes:
-----------------------------------
* Version 9.30
  - The TLSF memroy manager has been removed: The Runtime Environment
    contains now an own optimized memory manager that is tailored for GUI
    applications on resource constraint embedded systems.
    The Embedded Wizard Heap Manager is now used instead of TLSF.
  - The file ewmain.c is adapted to use the new memory manager.
    For debugging purposes the new function EwVerifyHeap() is called
    before the Garbage Collector is started, to check the memory integrity.
  - The project configuration is now done within the new file ewconfig.h.
    The file ewmain.c does no more contain configuration settings.
    The makefile/project files contain only those settings which have an
    impact to the project structure or the selection of files and libraries.
  - The interface between Embedded Wizard and the underlying hardware specific
    Board Support Package has been redesigned and aligned with all other
    platforms. Please have a look to the header files within the folder
    /TargetSpecific for more details.
  - Support of multi-touch: The touch driver ew_bsp_touch.c provides now
    multi-touch events. The main loop in ewmain.c has been adapted to
    process multi-touch events.
  - The files ew_bsp_serial.c/h are renamed to ew_bsp_console.c/h
  - Changed from MCUXpresso IDE V11.0.0 to MCUXpresso IDE V11.0.1
  - Changed to GCC ARM Embedded Toolchain 8-2019-q3-update
  - Test with Embedded Wizard V9.30 and iMX_RT Platform Package V9.30

* Version 9.20.03
  - Bugfix in ewextgfx.c for changed surface handling of 9.20.02 - possible
    access to surface flags via null pointer.

* Version 9.20.02
  - Improved managment of drawing operations done by PXP and CPU: Superfluous
    invalidation of the CPU cache or superfluous write-back of CPU cache are
    now avoided.
  - Improved handling of double-buffering: The time span between a completed
    drawing of the back-buffer and the occurence of the next V-sync can now be
    used by CPU to prepare next frame.

* Version 9.20.01
  - Changed from MCUXpresso SDK V2.4.1 to MCUXpresso SDK V2.6.1
  - Changed from MCUXpresso IDE V10.3.1 to MCUXpresso IDE V11.0.0
  - Changed to GCC ARM Embedded Toolchain 8-2018-q4-major

* Version 9.20
  - Test with Embedded Wizard V9.20 and iMX_RT Platform Package V9.20
  - The Graphics Engines for color format RGBA8888, RGB888 and RGB565 have
    been enhanced to support the new bitmap resource formats RGB565 and Index8.
  - The target specific module ew_bsp_graphics.c has been enhanced to support
    hardware accelerated drawing operations for the new source format RGB565.
  - The third-party software Xprintf is no more used and has been removed.
  - The dependency to printf() function is removed: The function EwFormat()
    does not exist anymore and has been removed from ewextrte.c. The function
    EwPrint() is now part of the RTE itself and implements a subset of the
    printf() format escape sequences (%d, %u, %f, %s, %c, %x, %X).
  - The new function EwConsoleOutput() has been added to the extern RTE
    module ewextrte.c. The function is used to print the given message on
    the console. No additional formatting, etc. is needed.
  - In case you get LCD underflows (e.g. flickering of LCD while PXP is active),
    you can increase the read priority for the LCD by modifying the NIC read_qos
    value for it. It is at 0x41044100 (register that isn’t in the header file).
    For more details see ew_bsp_display.c.
  - The set of provided examples has been enhanced. Please have a look into
    the subdirectory /Examples.
  - Realtime clock can be set by using new EwBspSetTime() function. RTC is
    now set to a default value during start of application (see ewmain.c).

* Version 9.10
  - Support of IMXRT1064-EVK
  - Test with Embedded Wizard V9.10 and iMX_RT Platform Package V9.10


The Build Environment:
----------------------
- The Build Environment is based on a Template approach.
  Within the subdirectory /Application you will find one common gcc/iar/keil/mcuxpresso
  project that is prepared for all Embedded Wizard examples and that can be used
  as a starting point for your development.
- Important project settings like 'ColorFormat' and 'ScreenOrientation'
  defined in the Embedded Wizard profile are imported automatically to the
  gcc/iar/keil/mcuxpresso project.
- A set of Embedded Wizard application examples can be found in the subdirectory
  /Examples.
- All target specific source codes (ew_bsp_xxx.c/h) that build the bridge
  between the Embedded Wizard generated code and the underlying NXP drivers
  are located within the folder /TargetSpecific.
- Please also note the toolchain specific notes in folder
  /Application/Project/<toolchain>/ReadMe.txt
