The device command window is the primary window that is different depending on which EVM is selected from the drop-down menu from the EVM Selection and Setup window. Some selections allow you to choose more than one device and a tab is created for each of the devices. The tab also shows the address number of the device as "Addr x". The user's guide for each EVM should be referenced for specific descriptions of the features or the devices and how it is implemented into the GUI.
The LEDMCUEVM-132 can be connected to several LED related EVMs to create your own system within the confines of what the GUI supports for EVMs and devices. Here are a few example Device windows, connections, and setups for using the LEDMCUEVM-132 with supported EVMs.
