# 1. Development environment preparation
|
|
|
|
1. install `"Arduino Software IDE"` for your preferred operating system
|
|
`https://www.arduino.cc -> Software->Downloads`
|
|
it is strongly recommended to use older version `"1.6.8"`, by which we can assure correct compilation results
|
|
_note: in versions `1.7.x` and `1.8.x` there are known some C/C++ compilator disasters, which disallow correct source code compilation (you can obtain `"... internal compiler error: in extract_insn, at ..."` error message, for example); we are not able to affect this situation afraid_
|
|
_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)_
|
|
|
|
2. 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 following way:
|
|
`File->Preferences->Settings` (`"More preferences can be edited in file ..."`)_
|
|
than do it
|
|
`Tools->Board->BoardsManager`
|
|
from viewed list select an item `"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)_
|
|
|
|
3. modify platform.txt to enable float printf support:
|
|
`"compiler.c.elf.flags=-w -Os -Wl,-u,vfprintf -lprintf_flt -lm -Wl,--gc-sections"`
|
|
|
|
# 2. Source code compilation
|
|
|
|
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/`
|
|
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 them into `"Firmware/"` directory
|
|
|
|
run `"Arduino IDE"`; select the file `"Firmware.ino"` from the subdirectory `"Firmware/"` at the location, where you placed the source codes
|
|
`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_
|
|
|
|
run the compilation
|
|
`Sketch->Verify/Compile`
|
|
|
|
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"`
|
|
_note: this file is created in the directory `"Firmware/"`_
|
|
|
|
# 3. Automated tests
|
|
## Prerequisites
|
|
c++11 compiler e.g. g++ 6.3.1
|
|
|
|
cmake
|
|
|
|
build system - ninja or gnu make
|
|
|
|
## Building
|
|
Create folder where you want to build tests.
|
|
|
|
Example:
|
|
|
|
`cd ..`
|
|
|
|
`mkdir Prusa-Firmware-test`
|
|
|
|
Generate build scripts in target folder.
|
|
|
|
Example:
|
|
|
|
`cd Prusa-Firmware-test`
|
|
|
|
`cmake -G "Eclipse CDT4 - Ninja" ../Prusa-Firmware`
|
|
|
|
or for DEBUG build:
|
|
|
|
`cmake -G "Eclipse CDT4 - Ninja" -DCMAKE_BUILD_TYPE=Debug ../Prusa-Firmware`
|
|
|
|
Build it.
|
|
|
|
Example:
|
|
|
|
`ninja`
|
|
|
|
## Runing
|
|
`./tests`
|
