Embedded Systems Downloads

• Compiler and development environment: Atmel tools installation page

• Circuit drawing: 123D Circuits

• 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

Windows: Installing and Configuring Realterm

• Driver install: 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.

Linux: Configuring and Starting CKermit

• 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.
