+// All this is about silencing the heat bed, as it behaves like a loudspeaker.
+// Basically, we want the PWM heating switched at 30Hz (or so) which is a well ballanced
+// frequency for both power supply units (i.e. both PSUs are reasonably silent).
+// The only trouble is the rising or falling edge of bed heating - that creates an audible click.

+// Of course, making non-sharp edges in digital technology is not easy, but there is a solution.
+// It is possible to do a fast PWM sequence with duty starting from 0 to 255.
+// Doing this at higher frequency than the bed "loudspeaker" can handle makes the click barely audible.
+// Technically:
+// timer0 is set to fast PWM mode at 62.5kHz (timer0 is linked to the bed heating pin) (zero prescaler)

+# This bash script is used to compile automatically the Prusa firmware with a dedicated build environment and settings
+# 
+# Supported OS: Windows 10, Linux64 bit
+#
+# Linux:
+#
+# Windows:
+# To execute this script you gonna need few things on your Windows machine
+#
+# Linux Subsystem Ubuntu
+# 1. Follow these instructions
+# 2. Open Ubuntu bash and get latest updates with 'apt-get upgate'
+# 3. Install zip with 'apt-get install zip'
+# 4. Add at top of ~/.bashrc following lines by using 'sudo nano ~/.bashrc'
+#
+#    export OS="Linux"
+#    export JAVA_TOOL_OPTIONS="-Djava.net.preferIPv4Stack=true"
+#    export GPG_TTY=$(tty)
+#
+#    and confirm them. Restart Ubuntu bash
+#
+# Or GIT-BASH
+# 1. Download and install the correct (64bit or 32bit) Git version https://git-scm.com/download/win
+# 2. Also follow these instructions https://gist.github.com/evanwill/0207876c3243bbb6863e65ec5dc3f058
+# 3. Download and install 7z-zip from its official website.
+#    By default, it is installed under the directory /c/Program Files/7-Zip in Windows 10 as my case.
+# 4. Run git Bash under Administrator privilege and navigate to the directory /c/Program Files/Git/mingw64/bin,
+#    you can run the command ln -s /c/Program Files/7-Zip/7z.exe zip.exe
+#
+# Useful things to edit and compare your custom Firmware
+# 1. Download and install current and correct (64bit or 32bit) Notepad++ version https://notepad-plus-plus.org/download
+# 2. Another great tool to compare your custom mod and stock firmware is WinMerge http://winmerge.org/downloads/?lang=en
+# 
+# Example for MK3: open git bash and change to your Firmware directory 
+# <username>@<machinename> MINGW64 /<drive>/path
+# bash build.sh 1_75mm_MK3-EINSy10a-E3Dv6full
+#
+# Example for MK25: open git bash and change to your directory 
+# gussner@WIN01 MINGW64 /d/Data/Prusa-Firmware/MK3
+# bash build.sh 1_75mm_MK25-RAMBo13a-E3Dv6full
+#
+# The compiled hex files can be found in the folder above like from the example
+# gussner@WIN01 MINGW64 /d/Data/Prusa-Firmware
+# FW351-Build1778-1_75mm_MK25-RAMBo13a-E3Dv6full.hex
+#
+# Version: 1.0.1-Build_8
+# Change log:
+# 12 Jan 2019, 3d-gussner, Fixed "compiler.c.elf.flags=-w -Os -Wl,-u,vfprintf -lprintf_flt -lm -Wl,--gc-sections" in 'platform.txt'
+# 16 Jan 2019, 3d-gussner, Build_2, Added development check to modify 'Configuration.h' to prevent unwanted LCD messages that Firmware is unknown
+# 17 Jan 2019, 3d-gussner, Build_3, Check for OS Windows or Linux and use the right build enviroment
+# 10 Feb 2019, ropaha, Pull Request, Select variant from list while using build.sh
+# 10 Feb 2019, ropaha, change FW_DEV_VERSION automatically depending on FW_VERSION RC/BETA/ALPHA
+# 10 Feb 2019, 3d-gussner, 1st tests with english only 
+# 10 Feb 2019, ropaha, added compiling of all variants and english only
+# 10 Feb 2019, 3d-gussner, Set OUTPUT_FOLDER for hex files
+# 11 Feb 2019, 3d-gussner/ropaha, Minor changes and fixes
+# 11 Feb 2019, 3d-gussner, Ready for RC
+# 12 Feb 2019, 3d-gussner, Check if wget and zip are installed. Thanks to Bernd to point it out
+# 12 Feb 2019, 3d-gussner, Changed OS check to OSTYPE as it is not supported on Ubuntu
+#                          Also added different BUILD_ENV folders depending on OS used so Windows
+#                          Users can use git-bash AND Windows Linux Subsystems at the same time
+#                          Cleanup compiler flags is only depends on OS version.
+# 12 Feb 2019, 3d-gussner, Added additional OSTYPE check
+# 15 feb 2019, 3d-gussner, Added zip files for miniRAMbo multi language hex files
+# 15 Feb 2019, 3d-gussner, Added more checks if
+#                                              Compiled Hex-files
+#                                              Configuration_prusa.h
+#                                              language build files
+#                                              multi language firmware files exist and clean them up
+# 15 Feb 2019, 3d-gussner, Fixed selction GOLD/UNKNOWN DEV_STATUS for ALL variants builds, so you have to choose only once
+# 15 Feb 2019, 3d-gussner, Added some colored output
+# 15 Feb 2019, 3d-gussner, troubleshooting and minor fixes
+# 16 Feb 2019, 3d-gussner, Script can be run using arguments
+#                          $1 = variant, example "1_75mm_MK3-EINSy10a-E3Dv6full.h" at this moment it is not possible to use ALL
+#                          $2 = multi language OR english only [ALL/EN_ONLY]
+#                          $3 = development status [GOLD/RC/BETA/ALPHA/DEVEL/DEBUG]
+#                          If one argument is wrong a list of valid one will be shown
+# 13 Mar 2019, 3d-gussner, MKbel updated the linux build enviromentto version 1.0.2 with an Fix maximum firmware flash size.

 ## Linux
-Run shell script build.sh to build for MK3 and flash with Sli3er.  
-If you have different printel model, follow step [2.b](#2b) from Windows build first.  
-If you wish to flash from Arduino, follow step [2.c](#2c) from Windows build first.  
 
-The script downloads Arduino with our modifications and Rambo board support installed, unpacks it into folder PF-build-env-\<version\> on the same level, as your Prusa-Firmware folder is located, builds firmware for MK3 using that Arduino in Prusa-Firmware-build folder on the same level as Prusa-Firmware, runs secondary language support scripts. Firmware with secondary language support is generated in lang subfolder. Use firmware.hex for MK3 variant. Use firmware_\<lang\>.hex for other printers. Don't forget to follow step [2.b](#2b) first for non-MK3 printers.
+1. Clone this repository and checkout the correct branch for your desired release version.
+
+2. Set your printer model. 
+   - For MK3 --> skip to step 3. 
+   - If you have a different printer model, follow step [2.b](#2b) from Windows build
+   
+3. Run `sudo ./build.sh`
+   - Output hex file is at `"PrusaFirmware/lang/firmware.hex"` . In the same folder you can hex files for other languages as well.
+
+4. Connect your printer and flash with PrusaSlicer ( Configuration --> Flash printer firmware ) or Slic3r PE.
+   - If you wish to flash from Arduino, follow step [2.c](#2c) from Windows build first.
+
+
+_Notes:_
+
+The script downloads Arduino with our modifications and Rambo board support installed, unpacks it into folder `PF-build-env-\<version\>` on the same level, as your Prusa-Firmware folder is located, builds firmware for MK3 using that Arduino in Prusa-Firmware-build folder on the same level as Prusa-Firmware, runs secondary language support scripts.

+  You can also use the 'prepare_winbuild.ps1' powershell script with Administrator rights
+- Tested versions are at this moment
+  - Ubuntu other may different
+  - After the installation and reboot please open your Ubuntu bash and do following steps
+  - run command `apt-get update`
+  - to install zip run `apt-get install zip`
+  - add few lines at the top of `~/.bashrc` by running `sudo nano ~/.bashrc`

+Now your Ubuntu subsystem is ready to use the automatic `PF-build.sh` script and compile your firmware correctly
+
+#### Some Tips for Ubuntu
+- Linux is case sensetive so please don't forget to use capital letters where needed, like changing to a directory
+- To change the path to your Prusa-Firmware location you downloaded and unzipped
+  - Example: You files are under `C:\Users\<your-username>\Downloads\Prusa-Firmware-MK3`
+  - use under Ubuntu the following command `cd /mnt/c/Users/<your-username>/Downloads/Prusa-Firmware-MK3`
+    to change to the right folder
+- Unix and windows have different line endings (LF vs CRLF), try dos2unix to convert
+  - This should fix the `"$'\r': command not found"` error
+  - to install run `apt-get install dos2unix`

+Q:I built firmware using Arduino and I see "?" instead of numbers in printer user interface.
+
+A:Step 1.c was ommited or you updated Arduino and now platform.txt located somewhere in your user profile is used.
+
+Q:I built firmware using Arduino and printer now speaks Klingon (nonsense characters and symbols are displayed @^#$&*°;~ÿ)
+
+A:Step 2.c was omitted.
+
+Q:What environment does Prusa use to build the firmware in the first place?
+
+A:Our production builds are 99.9% equivalent to https://github.com/prusa3d/Prusa-Firmware#linux this is also easiest way to build as only one step is needed - run single script, which downloads patched Arduino from github, builds using it, then extracts translated strings and creates language variants (for MK2x) or language hex file for external SPI flash (MK3x). But you need Linux or Linux in virtual machine. This is also what happens when you open pull request to our repository - all variants are built by Travis http://travis-ci.org/ (to check for compilation errors). You can see, what is happening in .travis.yml. It would be also possible to get hex built by travis, only deploy step is missing in .travis.yml. You can get inspiration how to deploy hex by travis and how to setup travis in https://github.com/prusa3d/MM-control-01/ repository. Final hex is located in ./lang/firmware.hex Community reproduced this for Windows in https://github.com/prusa3d/Prusa-Firmware#using-linux-subsystem-under-windows-10-64-bit or https://github.com/prusa3d/Prusa-Firmware#using-git-bash-under-windows-10-64-bit .
+
+Q:Why are build instructions for Arduino mess.
+
+Y:We are too lazy to ship proper board definition for Arduino. We plan to swich to cmake + ninja to be inherently multiplatform, easily integrate build tools, suport more IDEs, get 10 times shorter build times and be able to update compiler whenewer we want.
