Write a simple 8051 assembly language program for finding the smallest and largest number from a given array

; Code for finding the smallest number from internal memory locations ORG 00H MOV R0,#50H // Initialize the source memory pointer D: 0050H MOV R2,#05H // Initialize Iteration counter MOV B, @R0 /* Use B Register to store smallest value and initialize it to the first value*/ BACK: MOV A,@R0 /* Get the data from source memory pointer and Load into accumulator*/ CJNE A,B,LOOP /* Compare the data if not equal, go to relative address(LOOP)*/ LOOP: JNC LOOP1 // If carry generates, go to relative address LOOP1 MOV B,A // Store smaller value into B-register INC R0 // Increment the source memory pointer DJNZ R2,BACK /* Decrement iteration count and if it is not zero, go to relative address and repeat the same process until count become zero.*/ SJMP NEXT // Go to NEXT LOOP1: INC R0 // Increment the source memory pointer DJNZ R2,BACK /* Decrement iteration count and if it is not zero, go to relative address and repeat the same process until count become zero.*/ N

Write an assembly program for memory transfer

; Memory Transfer org 00h mov r0,#30h //source address D: 0030H mov r1,#40h //destination address mov r7,#05h //count, the number of data to be exchanged back: mov a,@r0 mov r4,a mov a,@r1 mov @r0,a mov a,r4 mov @r1,a inc r0 inc r1 djnz r7,back end

8051 Embedded C code for generating a triangular wave using an 8-bit DAC (Digital-to-Analog Converter)

#include <reg51.h> // Define the DAC output port #define DAC_PORT P1 // Function to generate delay void delay(unsigned int ms) { unsigned int i, j; for (i = 0; i < ms; i++) { for (j = 0; j < 123; j++); } } // Main function void main() { unsigned char dac_value = 0; unsigned char step = 1; while (1) { // Set the DAC output value DAC_PORT = dac_value; // Delay for a short period delay(1); // Update the DAC value for the next step dac_value += step; // Check if the DAC value reaches the maximum or minimum if (dac_value == 0xFF || dac_value == 0x00) { // Reverse the step direction step = -step; } } } /* In this code: We define the DAC output port as DAC_PORT, which is connected to port P1 of the 8051 microcontroller. The DAC board receives the 8-bit input from this port. The delay function is used to generate a short del
