driven by an LTC1157 MOSFET driver coupled to a MTD3055EL power FET. Both the LED
and the motor interfaces were discussed in a previous chapter.
10.1.4 UML ACTIVITY DIAGRAM
The SeaPerch control system UML activity diagram is provided in Figure 10.4. After initializing
ports, the control algorithm is placed in a continuous loop awaiting user input. In response to user
input, the algorithm determines desired direction of ROV travel and asserts appropriate control
signals for the LED and motors.
