2.1 Connecting to the GUI

Before connecting the MCF8329HSEVM to the computer, start up the MotorStudio application and select MCF8329HS from the drop down. Click on Proceed and then click on the Setup Now button for instructions on how to connect power, connect a motor, and configure the jumpers and switches on the EVM.

EVM Hardware Setup Figure 2-2 EVM Hardware Setup

Once the hardware setup is completed, turn on the power supply connected to the EVM. After the PVDD LED D3 lights up connect a micro-USB to USB cable between the EVM and PC. After a few seconds, MotorStudio should connect to the EVM and the two icons outlined in Figure 2-3 will turn green. If the EVM is not connecting click the Re-Scan button.

Note: If the GUI is not able to connect to the GUI after a minute, disconnect the EVM from the PC, restart the MotorStudio GUI. After MotorStudio has started again, reconnect the EVM to the PC.
