Using the On-board UART (Titanium)

The Titanium Ti60 F225 Development Board has a USB-to-UART converter connected to the Ti60's GPIOL_01 and GPIOL_02 pins. The Titanium Ti180 J484 Development Board has a USB-to-UART converter connected to the Ti180's GPIOR_67 and GPIOR_68 pins. To use the UART, simply connect a USB cable to the FTDI USB connector on the targeted development board and to your computer.

Note: The board has an FTDI chip to bridge communication from the USB connector. FTDI interface 2 on Ti60 and FTDI interface 0 on Ti180 communicate with the on-board UART. You do not need to install a driver for this interface because when you connect the Titanium Ti60 F225 Development Board or Titanium Ti180 J484 Development Board to your computer, Windows automatically installs a driver for it.

Finding the COM Port (Windows)

  1. Type Device Manager in the Windows search box.
  2. Expand Ports (COM & LPT) to find out which COM port Windows assigned to the UART module. You should see 2 devices listed as USB Serial Port (COMn) where n is the assigned port number. Note the COM number for the first device; that is the UART.

Finding the COM Port (Linux)

In a terminal, type the command:
ls /dev/ttyUSB*
The terminal displays a list of attached devices.
/dev/ttyUSB0 /dev/ttyUSB1 /dev/ttyUSB2 /dev/ttyUSB3

The UART is /dev/ttyUSB2.
