2.2 List of Software Items for Operation

In addition to the previously listed hardware items, the following software also is needed:

  • Download the Graphical User Interface (GUI) used to configure and monitor selected devices with the Fusion Digital Power designer.

The USB interface adapter is recognized by a PC as a generic human interface device (HID), which is supported by the built-in USB/HID drivers of the Windows operating system. Therefore, it is plug-and-play and no proprietary USB driver is required.

If flashing the firmware onto the USBGPIOv2 is necessary, go to UniFlash and download the needed firmware for the USBGPIOv2. Select the XDS110 Debug probe under detected devices (auto select option is also available). Then select MSP43E401Y under New Configuration and click start to proceed with the firmware download.
