- Mac OS X Mountain Lion
- Arduino IDE 1.0.4 configured and working with reaDIYmate
- Eclipse Juno for C/C++
Installation of Arduino Eclipse plugin
Good instructions for configuring the plugin for Mac OS X: Arduino Eclipse Development Environment for Mac OS X
Problems I encountered and how I solved them:
Problem 1: pins_arduino.h cannot be found
When creating my first new Arduino project I got the error below. As suggested here, I solved the problem by copying variants/readiymate/pins_arduino.h to cores/readiymate/ and refreshing and rebuilding.
pins_arduino.h: No such file or directory Arduino.h /reaDIYmate_board__ATmega1280__v1_5/readiymate line 212 C/C++ Problem
Problem 2: Arduino.h cannot be found
When building my project Arduino.h cannot be found:
Arduino.h: No such file or directory EclipseTest.h /EclipseTest line 9 C/C++ Problem
I tried solving this by editing the project settings and referencing the reaDIYmate_board_ATmega1280_v1_5 project. That did not help.
I imported the folder cores/readiymate/. It solved that compile error but now other things do not compile instead.
I eventually gave up and created a new project. It could compiled without problems! I deleted the bad project.
Problem 3: serial port already in use
When trying to upload to the board I got this error:
Serial port /dev/tty.usbserial-A90159P9 already in use. Try quiting any programs that may be using it Unknown Application
I quit the Arduino IDE that was also running. Didn’t help.
I unplugged and plugged in the Arduino. Didn’t help.
It turned out the upload was working despite the error. I did not notice this because I had not made changes and rebuilt my project before I uploaded it.
To get of the error message each time I did an upload I checked this setting in Eclipse’s preferences (not the projects): Arduino > Arduino > Disable RXTX
Follow the instructions in the Eclipse plugin’s FAQ: Mac I get the error “serial port is in use” when uploading
