Compiler and development environment: Atmel tools installation page
Subversion (source code sharing):
- Windows: Tortoise SVN
- OSX and Linux: install "subversion". The executable is "svn"
- Local notes on using SVN
Terminal interface: A terminal interface gives you a means of "talking" to your microcontroller with text. Once the microprocessor is connected to your computer and the terminal program is started and configured, anything that you type in the program's window will be sent to the microcontroller. And - anything that the microcontroller prints will be displayed on your computer.
- OSX: use "screen" (should already be installed with your OS): more detailed documentation
  From your terminal, type: screen /dev/tty.usbmodem26411 38400
  Note: the precise /dev name may be different on your machine. At the command line, execute ls -l /dev/tty.usb* to find yours (You may also have to try ls -l /dev/tty.cu*) .
- Linux: install ckermit.
- Windows: download RealTerm
  Download both drivers and save them into a new folder:
  - Old style Arduino Mega: Arduino MEGA 2560.inf
  - New style Arduino Mega (with 2x6 header next to the AREF pin): arduino.inf

Driver install:
(Note: this procedure may not be necessary for Windows 10)
Plug in Arduino board into USB. If you haven't installed the driver before, it will pop up a window and ask for driver. Choose "browse my computer for driver software." Next, click "Browse" and select the folder that contains the downloaded .inf files (above). Click "Next," and windows should be able to find the driver and install it with success. If the driver is correctly installed, you should see something like "Arduino Mega 2560 (COM7)" under "Ports (COM & LPT)" in the Device Manager (you can get to Device Manger in Control Panel). It may show a port number other than "COM7" (this is ok).
Open realterm:
- Click on the "Display" tab. Click "ANSI"
- Click on the "port" tab. Select BAUD 38400 and PORT to be the COM number from above. Click "Change."
- Now, anything that you type in the window will be sent to port 0 on your Arduino board. And, anything that your Arduino sends will be shown in the window.

The atmel device will likely show up as /dev/ttyACM0. After you plug the Arduino into your computer, you can check this by typing ls -l /dev/ttyAC*
Start ckermit at the command line

Type (or add the following to your ~/.kermrc file before starting ckermit):

       set line /dev/ttyACM0
       set speed 38400
       set carrier-watch off
       set handshake none
       set flow-control none

Then type:
```
       connect
       
```
Note: if you have problems with accessing the device, then you will need to configure the permissions for the device file. To do this permanently, place usb-serial udev rules into /etc/udev/rules.d and restart udev.
