The following table shows the target hardware for the application projects.

• Connect the Debug USB port on the board to the computer using a micro USB cable

• Connect the Debug USB port on the board to the computer using a micro USB cable

1. Build and program the application project using its IDE
2. Observe the high-side and low-side PWM waveforms on the oscilloscope
3. Observe the dead time between the high side and low side

   

4. Refer to the table below for PWM channels oscilloscope connections:
