Design the interface for a positive logic switch to TM4C123GXL Port A pin 7. Show formulas and calculations for each circuit element. Draw the circuit schematics with components labelled with their names and values. Write the C code as a function to initialize the port for interfacing the switch. Write a function to read the data value of Port A pin 7. Comment your code to explain each initialization step clearly.

Draw a circuit to implement a switching network with two data inputs (A and B), two data outputs (C and D), and a control input (S). If S=1, the network is in pass-through mode: C=A and D=B. If S=0, the network is in crossing mode: C=B, and D=A. Use the most reasonable combinational building blocks or gates. Label the inputs and outputs.

Given in the figure is IC 7474 pin configuration. The pin connections of the IC is provided in the Table for the design of a particular counting sequence. What is that counting sequence for which it is desined.

Draw the symbols for a Normally Open (NO) limit switch and a Normally Closed (NC) limit switch, both in the un-actuated and actuated states.

Question 2 In Figures 2, 3, 4 and 5 the designation of the state of the MISO signal is "Hi-Z" before an. after the SS signal is low. This means the output driving the signal is turned completely off and not driving the signal either high or low. "Hi-Z" means "High Impedance". Also in the figures, the designation of the state of the MOSI signal is "XXX" before and after the SS signal is low. This means the state of the signal is "Unknown" or "Don't Care". If there are multiple Slaves on the bus, why must a Slave turn off the driver (Hi-Z) on the. MISO signal when their SS signal is high

1.1 Design a circuit for the traffic light unit in Multisim. The design should include 3 positive edge triggered D flip-flops. Set your clock signal to 1Hz. Please include Four screenshots of your working circuit, with each screenshot showing each of the light configurations shown in Figure 1. 000 100 010 110 001 Figure 1. A state diagram for a traffic light control The design should include 3 positive edge triggered D flip-flops. Use 1 flip-flop to control the on and off of a given light, and the state machine should switch from Red (100) -> Red and Amber (110) - > Green (001) -> Amber (010) and repeat the cycle again, with the following transition table: Current state Next state 000 100 100 110 110 001 001 010 010 100 ABC A*B*C* Table 1.
