An embedded system incorporates an MSP430F2274 clocked by a4.096MHz
at 3.3V, driving two seven-segment displays and two discrete LEDs.The sevensegment
display draws 7.5mA per segment at 1.8V and the discrete LEDs
operate with 10mA each at 1.6V. Three push-buttons are needed forcompleting
the user interface. Design a suitable interface to connect allLEDs,
seven-segments, and push-buttons. Estimate the circuit powerrequirements
and recommend a non-regulated power supply and a suitableregulator.
