TTL Converter Terminal Connection

This section shows you how to connect your Evaluation Kit with a host computer to login to a terminal.

Linux

Note

This section was tested on Ubuntu 16.04.

  1. Install minicom:
sudo apt install minicom
  1. Power on the board.
  2. Use the TTL to USB Serial Converter cable to connect your computer with the board.
  3. Get the right ttyUSB instance:
$ ls /dev/ttyUSB*
/dev/ttyUSB0
  1. Connect minicom to the /dev/ttyUSB0 device:
minicom -D /dev/ttyUSB0 -t linux

Tip

You should consider using minicom with logfiles. They can be enabled with the -C option. An example would be: minicom -D /dev/ttyUSB0 -t linux -C ${HOME}/log/minicom/minicom_usb0_$(date +%Y-%m-%d).log.

Note

By default you can quit minicom hitting CTRL + A and then Q.

Windows

You will need a host computer with a terminal program, e.g. PuTTY.

The following example is for a Windows 10 host system.

  1. Power on the board.
  2. Use the TTL to USB Serial Converter cable to connect your computer with the board.
  3. Check the Device Manager to see as which COM the USB connected.
  4. For example, it would come up as COM9, configure PuTTY as follows:
PuTTY configuration
  1. Hit “Open” and you should get terminal access to your board. Sometimes you have to hit the [Enter] key before you get an output.

Hint

If your computer is not recognizing the TTL to USB Serial Converter cable you might try installing this driver: http://www.ftdichip.com/Drivers/CDM/CDM21228_Setup.zip
