- 10. Consider you are interfacing a switch and two LEDS (L1 and L2) with LPC1769 MCU. • When the switch is ON (logic HIGH), LI is ON, and L2 is OFF. • When the switch is OFF (logic LOW), L1 is OFF, and L2 is ON. • Switch is interfaced with port 1- pin 2, L1 with port 1- pin 3, and L2 with port 1- pin 4. • Initially L1 is ON, and L2 is OFF. Complete the C program template for this task given below. Demonstrate all steps: Pin function configuration, mode selection, and writing/reading of pin values correctly. #include int main (void)Computer Science 1. Design a circuit for a digital lock using the minimum number of D latches. The lock has two input push-button switches A, B and it outputs a single pulse (Z1) for each activation i.e. lock open. The two switches are interlocked mechanically so that simultaneous pulses are not possible. The lock should have the following features: a. The opening sequence is 0011. ii. Then replace ‘0’ by ‘A’ and ‘1’ by ‘B’ in the sequence. b. Five B pulses should give an absolute reset. c. Any incorrect use of the A switch will cause an output (Z2) to ring a bell to warn that the lock is being tampered.9. A multiplexer is a switching circuit that produces as its single output one of a set of inputs based on the value of some additional inputs called the controls. Given that 0, 1, 2, and 3 in two-bit binary are 00, 01, 10, and 11, respectively, draw a 2-bit multiplexer using the three basic logic gates with inputs xo, x1, x2, and x3, and two control inputs co and c1. Setup the circuit so that x; is the single output, where i if the value of the 2-bit integer (cico)2. NOTE: This is not a Boolean product; instead it's the binary representation of an integer where c1 is the most significant bit and co is the least significant bit.
- Assume we are writing a testbench for a sequential circuit that has three control inputs (cA, cB, cC) and a periodic clock (clk). If we define CLK_PERIOD as a localparameter with a value of 50 (nsec), write the testbench segment that would ensure all possible combinations of the control inputs were tested on a clock rising edge. This is can be done more elegantly if you define each time step in terms of the constant CLK_PERIOD. Your answer should include the statements that define clk, cA, cB, and cC over time. Hint: think of how you would show all combinations of three variables on a truth table and replicate that over time, where each combination is held over a timespan with a clock triggering edge.The connection diagram shows multiple gates and the pins assigned to each gate. For example, from the datasheet connection diagram of IC 7400, four individual NAND gates can be observed. Pins 1, 2 and 3 are all related to one of the four NAND gates. For each gate the top input is assigned the letter A while the bottom input is assigned B and the output is assigned the letter Y. The function tables of the ICs are normally given in terms of H (High logic level) and L (Low logic level). Referring to the datasheet function table of IC 7400 shows the four different input combinations of A and B and the corresponding output Y for one of the four NAND gates. There is also one more letter assignment that could be found in function tables, this is the letter X, a don't care assignment. In cases where an X is given, it can be replaced by either an H or L assignment without effecting the resultant functionality of the IC. An example of this case can be seen for the function table of IC 7402. The…The picture below shows the intersection of a road. Some vehicle detection sensors are placed along lanes C and D (main road) and lanes A and B (access road). These sensors outputs are LOW (0) when no vehicle is present and HIGH (1) when a vehicle is present. The intersection traffic light is to be controlled according to the following logic: The east-west (E-W) traffic light will be green whenever both lanes C and D are occupied. The E-W light will be green whenever either C or D is occupied but lanes A and B are not both occupied. The N-S light will also be green whenever both lanes A and B are occupied but C and D are not both occupied. The N-S light will also be green when either A or B is occupied while C and D are both vacant. The E-W light will be green when no vehicles are present. Using the sensor outputs A, B, C and D as inputs, design a logic circuit to control the traffic light. There should be two outputs-S and E-W that go HIGH when the corresponding light is to be…
