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.

Draw the schematic for a synchronous 3-digit up/down counter with T flip-flops, with an enable function. So there will be two control lines: En and DIR. When En = 0, the counter stops. When En = 1, the counter counts. DIR determines the counting direction. When DIR = 1, the counter counts upward. When DIR = 0, the counter counts downward. %3D

Give six examples of the various process technologies that are employed to produce the programmable connections of PLDs.

Write a Ladder Logic PLC program for each of the following scenarios.  Label all contacts and coils in the PLC program. Scenario 1 Turn on a light when either one of two switches (I1, I2) is toggled on (construct an OR Gate).  Turn on a second light when both switches (Same inputs I1, I2) are toggled on (construct an AND Gate).  Turn on a third light when both switches (Same inputs I1, I2) are toggled off (construct a NOR Gate).  Turn on a fourth light when either switch (Same inputs I1, I2) is toggled off (construct a NAND Gate).  Print a copy of the program showing the construction of the four gate configurations.  Also, submit a truth table for the four input configurations.    Then modify your program so, only one light turns on at a time as you toggle the four truth table states. Scenario 2 Construct a seal-in circuit using a stop-and-start pushbutton and an internal coil to seal in.  Turn on a light for 10 seconds when the start button is pushed then turn it off automatically or…
