The setup of the eclipse based development environment for Arduino is a bit of a challenge. Following my setup procedure, based upon Robert Carlsen's Blog on a Mac OS X Snow Leopard and a Boardiuno:
- install XCode if not already done (else make will fail)
- install Cross Pack for AVR development
- install Arduino IDE
- Download and install Eclipse for C/C++ developers
- Install the AVR-Eclipse Plugin to Eclipse
- Help -> Install new software
- http://www.eclipse.org/downloads/ is the update site
- restart eclipse
- check the paths in Eclipse preferences / AVR / Paths
- should point to the cross pack
- Atmel Part Description Files is not needed
- add a AVRDude config (Eclipse preferences / AVR / AVRDude -> Add)
- Name: Boarduino
- Programmer Hardware: STK500 Version 1.x
- Baudrate: 57600
- Set port (find the port by 'ls /dev/cu.*', i.e. /dev/cu.usbserial-FTELSJ9T)
- create a new CPP project (or checkout my template)
- New C++ Project
- AVR Cross Target Application
- don't press finish, but next
- select hardware (ATMega 328P and 16 Mhz (16000000) for Boarduino)
- finish
- Open the properties of the newly created project
- AVR / AVRDude: Select the programmer ("Boarduino")
- under C/C++ Build/Settings (for both targets, Debug and Release)
- under "Additional Tools in Toolchain" check only:
- Generate HEX file for flash
- Print Size
- AVRDude (optional, directly uploads after compilation)
- under AVR compiler
- change command from "avr-gcc" to "avr-g++"
- Directories: add "/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino"
- Debugging: no debugging info
- Optimization: size (-Os)
- under AVR C++ compiler
- change command from "avr-gcc" to "avr-g++"
- Directories: add "/Applications/Arduino.app/Contents/Resources/Java/hardware/arduino/cores/arduino"
- Debugging: no debugging info
- Optimization: size (-Os)
- under AVR C++ Linker
- Add Library
- Name: core
- Add Library Path
- Path: ${workspace_loc:/Blink/lib} (if the project name is "Blink")
- Open Arduino IDE and an example project
- set your Arduino (in Tools/Board)
- Click Verify/Compile in the toolbar while pressing shift
- Extract the folder name from the log-panel (beginning with /var/folders/....)
- copy the core.a from the folder into <eclipse-project>/lib/libcore.a
- Compile the project in Eclipse
Notes:
you might have to define
extern "C" void __cxa_pure_virtual(void);
void __cxa_pure_virtual(void) {}
in your projects main.
And also:
#undef int
#undef abs
#undef double
#undef float
#undef round
if you get compile errors in math.h and several other system-files.
Versions used:
- Eclipse 20100218-1602 (3.5 SR2)
- AVR Eclipse 3.2.1
- Arduino IDE 0018
- CrossPack AVR 20100115
Good luck.
