48
# It is suggested that you install it at ~/opt/arduino if you are unsure.
50
# If you downloaded the Arduino software manually and unpacked it somewhere
51
# other than ~/opt/arduino, you will need to set up ARDUINODIR to be the path

53

# You also need to set up a couple of environment varibales. ARDUINODIR should
47
# be set to the path where you unpacked the arduino software from arduino.cc

54
49
# your ~/.profile by adding something like this:
56
51
# export ARDUINODIR=~/somewhere/arduino-1.0
58
# You will also need to set BOARD to the type of Arduino you're building for.
59
# Type `make boards` for a list of acceptable values. You could set a default
60
# in your ~/.profile if you want, but it is suggested that you specify this at
61
# build time, especially if you work with different types of Arduino. For
53
# You will also need to set BOARD to the type of arduino you're using. This
54
# can be done when running make (or you could set a default in ~/.profile and
55
# iverride it as necessary). For example:
64
57
# $ export BOARD=uno
67
60
# You may also need to set SERIALDEV if it is not detected correctly.
