11. Using TW-Terminal2
TW_Terminal2.exe is a Microsoft Windows based program provided with the evaluation board for
testing, debugging, and updating firmware. Updating the firmware of the built-in microcontroller of
the TW8816 will require the use of the USB Interface Board and a special cable. Any other
features that require the I2C or SPI control will require the use of the USB Interface Board. The
TW_Terminal2 application has terminal emulation capabilities and has all the functionalities of the
HyperTerminal with the RS-232 connection. It also provides a friendly graphical user interface to
access and control the TW8816 registers. With this application, changing and monitoring
registers are made simpler and the user has better visibility. It allows faster firmware upgrade
without the need of an external eeprom programmer and a simple window interface for settings
such as gamma, decoder, ADC, scaler, and much more. Also, the flexible user interface can be
custom designed to the customer’s need by the use of TW_VEditor application.
