Operating Menu 3.1 Start-up To start the system, wake up either with negative edge at input pin LIN on the motor board or positive edge on EN2 by pressing EN2 button on the motor board. The Start-up Screen is dis- played (see Figure 3-1). Figure 3-1. Start-up Screen The first line shows the software version. The second line shows the wake-up source, either LIN or EN2. The third line shows the status of the temperature comparator. The fourth line shows the operating voltage, either 5.0V or 3.3V. In the system version 1.0, only 5V operating voltage is supported. 3.2 Intro Screen After 3 seconds, the Intro Screen is displayed (see Figure 3-2). Figure 3-2.
