Tabulate the truth table for an 8x4 ROM that implements the Boolean functions
4(x, y, z)=(1,2,4,6)
B(x, y, z)=(0,1.,6,7)
C(x, y, z)=(2,6)
D(x, y, z)=(1,2,3,5,7)
Write a piece of VHDL code to generate a block ROM of size 1024X8bit (or 1KB ROM), and a block RAM of size 1024X8bit (or 1KB RAM).
Draw the complete working schematic for the interface of PIC microcontroller with a single digit seven segment display so that the following pins are connected to the digits of the 7 segment display as follows: RE0 connected to a, RE1 for b, RE2 for c, RD0 for d, RD1 for e, RD2 for f, RD3 for g, RD4 for decimal point. Also show a temperature sensor connected to RA0 for reading the analog input. Write a short program to initialize the corresponding ports and show the character ‘A’ followed by the character ‘b’ with a 1 second delay in a continuous loop. Clearly show how the patterns for the characters are derived and used for the program in a neat table.

As in what things should I look for in the data sheet? How do I also correspond to what registers on the SSD1331 display with the registers on the board, and what if that board does not have a DC register? What are other ways of analyzing if they have a DC pin but its not called DC?Can you simplify a clear detailed explanation of how I would use SPI to interact with SSD1331 if there are multiple buses that SPI can read from?arrow_forwardIn firmware development if I wanted to develop a driver for the SSD1331, what is the thought process in reading the datasheet?

- Which of the following statements is false? 1. Incremental optical encoder with one photodetector cannot be used to determine the rotation angle directly. 2. The only way to read an encoder pattern is to use optical sensors like photodetectors. 3. Incremental optical encoder with two photodetectors can be used to determine the direction of the rotation. 4. Absolute encoders use a more complex disk pattern and multiple photodetectors to read out the angular position directly. 5. Incremental optical encoder with one photodetector cannot be used to determine the direction of the rotation.arrow_forwardAdvantages of Custom ASIC design over FPGA's include Select one: a.

- I could use some help with making a working code for a 12 hour clock system in verilog for my DE0lite or any other Fpga Board. I am being unable to get the results correctarrow_forwardUse the following components from the Proteus library: PIC16F877 7SEG-MPX2-CC LED-BLUE (3 items) LED-GREEN LED-YELLOW KEYPAD-SMALLCALC Connect items to the microcontroller: (1) Connect the keypad to the PORTC; (2) Connect the 7-segment display unit to PORTC (data) and the lowest to pins of PORTD (selection); (3) Connect three blue LEDs to the highest four pins of PORTE, and (4) Connect other LEDs as you wish. This configuration should function as a simple calculator: It accepts one or two-digit numbers and three operators (+,-,/) (divide operator results, integer division). A green LED should be ON while the user is expected to enter numbers. If the user enters a third digit while entering any number, a yellow LED should warn the user by blinking. After entering the first number, the user should select the operation and enter the second number. The user should press the equality (=) key to display the result on display. One of the blue LEDs should indicate the selected operation…arrow_forwardProblem: Our task will be to design a VHDL component that provides basic stop watch functionality. Your design should start at 0 and be able to count up on the right-most 7-segment displays (the other two displays should be blank). Pressing the center button causes the count to start and stop. The down button resets the counter to 0. The slide switches should be used to enter a stop value in binary. When the count reaches this stop value, the 16 leds on the board will create a complex victory pattern.arrow_forward
