SOME STUPID TOOK THIS QUESTION AND ANSWERED IT (AS HE/SHE CLAIMS ) BUT THE ANSWER WAS ACTULLY PART OF THE GIVEN INFO. IN THE PROBLEM ITSELF :)

WRITE ME A WORKING PROGRAM THAT I CAN RUN ON EDSIM SOFTWARE FOR 8051 MICROCONTROLLER PLEASE I HAVE HAD ENOUGH HARD TIME GETTING MY Q'S ANSWERED BY CHEGG E X P E R T :)

Using the example hw5 lcd.asm (attached with the assignment) as a starting point, write an LCD code that will display your name on the LCD in the EdSim51 simulator. Your first name should be displayed on the first line, and your last name on the second line.

provide COMMENTS IN ALL CAPS for each line you add, be detailed

content of the file:

; Initialize the LCD and then

; send the string STR to the it

;

RS EQU P1.3

E EQU P1.2

D7 EQU P1.7

D6 EQU P1.6

D5 EQU P1.5

D4 EQU P1.4

part B

Modify your code from part a to make your name flashes. The name should be ON for a period of time OFF for the same period. For the purpose of this problem, use an update frequency of 200 in the simulator.
