### Using Arduino

+_Note: Multi language build is not supported._

#### 1. Development environment preparation
- a. install `"Arduino Software IDE"` for your preferred operating system
-`https://www.arduino.cc -> Software->Downloads`
-it is recommended to use version `"1.8.5"`, as it is used on out build server to produce official builds.
-_note: in the case of persistent compilation problems, check the version of the currently used C/C++ compiler (GCC) - should be `4.8.1`; version can be verified by entering the command
-`avr-gcc --version`
-if you are not sure where the file is placed (depends on how `"Arduino Software IDE"` was installed), you can use the search feature within the file system_
-_note: name collision for `"LiquidCrystal"` library known from previous versions is now obsolete (so there is no need to delete or rename original file/-s)_
+**a.** Install `"Arduino Software IDE"` from the official website `https://www.arduino.cc -> Software->Downloads`
+
+ _It is recommended to use version `"1.8.5"`, as it is used on out build server to produce official builds._
- b. add (`UltiMachine`) `RAMBo` board into the list of Arduino target boards
-`File->Preferences->Settings`
-into text field `"Additional Boards Manager URLs"`
-type location
-`"https://raw.githubusercontent.com/ultimachine/ArduinoAddons/master/package_ultimachine_index.json"`
-or you can 'manually' modify the item
-`"boardsmanager.additional.urls=....."`
-at the file `"preferences.txt"` (this parameter allows you to write a comma-separated list of addresses)
-_note: you can find location of this file on your disk by doing the following:
-`File->Preferences->Settings` (`"More preferences can be edited in file ..."`)_
-then choose
-`Tools->Board->BoardsManager`
-from viewed list and select the item labeled `"RAMBo"` (will probably be labeled as `"RepRap Arduino-compatible Mother Board (RAMBo) by UltiMachine"`
-_note: select this item for any variant of board used in printers `'Prusa i3 MKx'`, that is for `RAMBo-mini x.y` and `EINSy x.y` to_
-'clicking' the item will display the installation button; select choice `"1.0.1"` from the list(last known version as of the date of issue of this document)
-_(after installation, the item is labeled as `"INSTALLED"` and can then be used for target board selection)_
+**b.** Setup Arduino to use Prusa Rambo board definition
- c. modify platform.txt to enable float printf support:
-add "-Wl,-u,vfprintf -lprintf_flt -lm" to "compiler.c.elf.flags=" before existing flag "-Wl,--gc-sections"
-example:
-`"compiler.c.elf.flags=-w -Os -Wl,-u,vfprintf -lprintf_flt -lm -Wl,--gc-sections"`
-The file can be found in Arduino instalation directory, or after Arduino has been updated at:
-"C:\Users\(user)\AppData\Local\Arduino15\packages\arduino\hardware\avr\(version)"
-If you can locate the file in both places, file from user profile is probably used.
+ * Open Arduino and navigate to File -> Preferences -> Settings
+ * To the text field `"Additional Boards Manager URLSs"` add `https://raw.githubusercontent.com/DRracer/Arduino_Boards/master/IDE_Board_Manager/package_prusa3d_index.json`
+ * Open Board manager (`Tools->Board->Board manager`), and install `Prusa Research AVR MK3 RAMBo EINSy board`
+
+**c.** Modify compiler flags in `platform.txt` file
+
+ * The platform.txt file can be found in Arduino instalation directory, or after Arduino has been updated at: `"C:\Users\(user)\AppData\Local\Arduino15\packages\arduino\hardware\avr\(version)"` If you can locate the file in both places, file from user profile is probably used.
+
+ * Add `"-Wl,-u,vfprintf -lprintf_flt -lm"` to `"compiler.c.elf.flags="` before existing flag "-Wl,--gc-sections"
+
+ For example: `"compiler.c.elf.flags=-w -Os -Wl,-u,vfprintf -lprintf_flt -lm -Wl,--gc-sections"`
+
+_Notes:_
+
+
+_In the case of persistent compilation problems, check the version of the currently used C/C++ compiler (GCC) - should be at leas `4.8.1`;
+If you are not sure where the file is placed (depends on how `"Arduino Software IDE"` was installed), you can use the search feature within the file system_

#### 2. Source code compilation
-a. place the source codes corresponding to your printer model obtained from the repository into the selected directory on your disk
-`https://github.com/prusa3d/Prusa-Firmware/`
+**a.** Clone this repository`https://github.com/prusa3d/Prusa-Firmware/` to your local drive.
-b. In the subdirectory `"Firmware/variants/"` select the configuration file (`.h`) corresponding to your printer model, make copy named `"Configuration_prusa.h"` (or make simple renaming) and copy it into `"Firmware/"` directory.
+**b.** In the subdirectory `"Firmware/variants/"` select the configuration file (`.h`) corresponding to your printer model, make copy named `"Configuration_prusa.h"` (or make simple renaming) and copy it into `"Firmware/"` directory.
-c. In file `"Firmware/config.h"` set LANG_MODE to 0.
+**c.** In file `"Firmware/config.h"` set LANG_MODE to 0.
-run `"Arduino IDE"`; select the file `"Firmware.ino"` from the subdirectory `"Firmware/"` at the location, where you placed the source code
-`File->Open`
-make the desired code customizations; **all changes are on your own risk!**
+**d.** Run `"Arduino IDE"`; select the file `"Firmware.ino"` from the subdirectory `"Firmware/"` at the location, where you placed the source code `File->Open` Make the desired code customizations; **all changes are on your own risk!**
-select the target board `"RAMBo"`
-`Tools->Board->RAMBo`
-_note: it is not possible to use any of the variants `"Arduino Mega …"`, even though it is the same MCU_
+**e.** Select the target board `"Tools->Board->PrusaResearch EINSY RAMBo"`
+ _note: It is not possible to use any of the variants `"Arduino Mega …"`, even though it is the same MCU_
-run the compilation
-`Sketch->Verify/Compile`
+**f.** Run the compilation `Sketch->Verify/Compile`
-upload the result code into the connected printer
-`Sketch->Upload`
+**g.** Upload the result code into the connected printer `Sketch->Upload`
-or you can also save the output code to the file (in so called `HEX`-format) `"Firmware.ino.rambo.hex"`:
-`Sketch->ExportCompiledBinary`
-and then upload it to the printer using the program `"FirmwareUpdater"`
+* or you can also save the output code to the file (in so called `HEX`-format) `"Firmware.ino.rambo.hex"`: `Sketch->ExportCompiledBinary` and then upload it to the printer using the program `"FirmwareUpdater"`
_note: this file is created in the directory `"Firmware/"`_
