Help with ATMEGA328P ADC conversion

Other Hardware Sensors
1

I am trying to get the ADC of the ATMEGA 328P to do a conversion with the use of interrupts and once the conversion is complete, I need it to print ^Conversion Complete^ on a 16x2 LCD.I am currently using Proteus simulator to observe these results. My problem is when the LCD does not print anything at all. The LCD initialization, delay and printing subroutines work fine when used alone, without the interrupts or the ADC conversion initialization. Im not sure if I have placed the interrupts in correct position or if I have used the memory allocations using .ORG correctly.My code is as below

    ORG 0x00
    JMP START
    
    .ORG 0x002A ; Address of the ADC conversion complete interrupt
    JMP ADC_vect
    .ORG 0x0020 ; Address of the Timer0 overflow vector
    JMP TIMER0_OVF_vect
    
    .ORG 0x100
   ;string definitions 
  
    START:
    LDI temp, HIGH(RAMEND)
	OUT SPH, temp
	LDI temp, LOW(RAMEND)
	OUT SPL, temp

SENSOR_MAIN:
    LDI temp, (1<<REFS0)
    STS ADMUX, temp
    LDI temp, (1<<ADEN)|(1<<ADATE)|(1<<ADIE)|(1<<ADPS2)|(1<<ADPS1)|(1<<ADPS0)
    STS ADCSRA, temp
    LDI temp, (1<<ADTS0)|(1<<ADTS1)|(1<<ADTS2)  
    STS ADCSRB, temp
    LDI temp, (1 << TOIE0)
    STS TIMSK0, temp
    LDI temp,0x03
    STS TCCR0B, temp
    SEI
    
    TIMER0_OVF_vect:
    ;setting up delay of 1ms
    LDI temp, 131
    OUT TCNT0, temp
    LDS temp, ADCSRA
    SBRS temp, ADSC  
    RJMP SKIP_ADC_START
    ;start ADC conversion
    LDI temp, (1<<ADSC)
    STS ADCSRA, temp
    SKIP_ADC_START:
    RETI
   
    ADC_vect:	
    LDS temp, ADCSRA
    SBRS temp, ADIF
    RJMP NOT_COMPLETE
    RCALL Conversion_Complete
    LDI temp, (1<<ADIF)
    STS ADCSRA, temp
    NOT_COMPLETE:
    RETI
   
    Conversion_Complete:
    LDI ZH, HIGH(conversion_string)
    LDI ZL, LOW(conversion_string)
    LDI temp, CMD_SET_BEGLINE
    CALL lcd_write_string
    LDI ZH, HIGH(complete_string)
    LDI ZL, LOW(complete_string)
    LDI temp, CMD_SET_BEGLINE
    CALL lcd_write_string
    RET

This is not an Arduino question.
For bare machine code you better ask in a dedicated AVR forum.

IMO interrupts and simulation do not fit together very well.

Using Serial I/O in an interrupt routine is not recommended. Did you consider the time between the interrupt and end of the text output? IMO it's sufficient to check for ADC completion in the main thread and output the message there.
