5. Open Windows Explorer and change to the project folder: \UDP_Software_vX.X\Demo\SiM3L1xx\ (where
vX.X is the version number of the UDP software).
6. Double click on the “Install_Si70xx.bat” file in the project folder. This opens a command window and
downloads the pre-built image file (UDP_Demo_Si70xx.hex) to the MCU card.
7. Verify that “Success. No errors reported.” is displayed in the command window.
8. Press any key to close the command window.
The demo software displays temperature and humidity on the LCD. The LCD is updated twice a second with new
temperature and humidity readings. If you prefer the temperature to be displayed in Fahrenheit, then press the S1
button.
The demo software is now installed on the MCU card and the USB Debug Adapter is no longer needed. Disconnect
the USB Debug Adapter from the debug connector on the MCU card.
