| # Usage: | |
| # | |
| # Uncomment these lines and set them appropriately according to | |
| # the Arduino libraries you need: | |
| # | |
| # BOARD_TAG = teensy3 | |
| # ARDUINO_DIR = /Applications/Arduino.app/Contents/Resources/Java | |
| # ARDUINO_VERSION = 104 | |
| # ARDUINO_LIBS = Bounce LiquidCrystal LedControl Encoder | |
| # USER_LIBS = <your own sketchbook libraries> | |
| # | |
| # Or you can set them in a small Makefile and include this file with: | |
| # include Teensy.mk | |
| # | |
| # Use OPTIONS to change the USB mode and language (as well as | |
| # insert your own defines): | |
| # OPTIONS = -DLAYOUT_US_ENGLISH -DUSB_SERIAL | |
| # See $(ARDUINO_DIR)/hardware/teensy/build.txt for possible values. | |
| # | |
| # Targets: | |
| # make - no upload | |
| # make clean - remove all our dependencies | |
| # make distclean - remove the build directory | |
| # make upload - upload (using Teensy uploader) | |
| # make reset - reset the board | |
| # make raw_upload - upload without first resetting | |
| # | |
