Software Installation and Operation

Users downloading the Picor Buck GUI should save the compressed file in a desired directory. The user should

unzip the compressed file and run the executable installation file “PicorBuckGuiFull.exe”. The installer will then

install the Picor Buck GUI in either the default Programs directory or to a directory specified by the user. Once the

software is installed, the user should next plug in the LinkM into a dedicated USB port. The LinkM will detect and

use a valid driver without the need of installing one. If the LinkM device is not detected, the user should consult

the LinkM homepage at http://linkm.thingm.com/. If the LinkM is not installed, the Picor Buck GUI will not start

and an error message will be generated like the one shown in Figure 3.

Successful installation of the LinkM Interface should result in a successful start up screen of the Picor Buck GUI as

shown in Figure 4. First a dialog box will pop up indicating proper detection of the LinkM. When the user clicks the

“OK” button, that box will disappear. The Picor Buck GUI program screen will appear as shown in the bottom half

of Figure 4.
