Advanced chip samples are available for the evaluation of standby current consumption.

6 Rev A2, Page 6/7 GETTING STARTED Step Description Download GUI-Software For the evaluation software please check The package includes all files which are necessary for operation. Install GUI-Software When download is finished, open the download folder and double click "TW111SO_gui_XX/setup.exe". Follow the instructions on the screen. Connect Demoboard Plug the mini-usb cable to the ic-tw11_1c mini-usb connector and find a free USB slot on your Windows PC. The green "Power" LED will light up once the board is powered. Start GUI-Software Double click on the TW111SO_gui_XX.exe in your installation folder to start the GUI. The red "SPI active" LED indicates that the MCU is driving the SPI interface now. Start the Help system To help you interact with the GUI, there is a help system which teaches you about the main features of the GUI software. You will find the help system in the menubar "Help", as shown below. Figure 6: Help system
