The document presents a project by Fawad Masood Khattak on using the EMU8086 emulator to maintain a constant temperature using a heater and thermometer. It details the programming instructions for reading temperature from a specific port and controlling the heater based on temperature readings while illustrating the necessary commands and procedures. The document concludes with an endless loop for continuous temperature monitoring.

- 1. IN The Name Of Almighty ALLAH
- 2. Presentation Title Page Name:Fawad Masood Khattak ID: (CU-58-2011) Section A EE-2011A Topic: emu8086 shows how to keep constant Temperature Contact : Fawadkttk@gmail.com CECOS University Peshawar,Pakistan
- 3. Thermometer by Fawad Masood Ktk It is also accessible from the "virtual devices" menu of the emulator.
- 5. Temperature Range Fawad Masood Ktk Temperature Range Is In Between of 60 Degree to 80 Degree
- 6. Use of : Fawad Masood Ktk Using Heater and Thermometer It is assumed that air temperature is lower 60°. Temperature Rises Fast thus Emulator Should Be Set Run At Maximum Speed
- 7. #Start=thermometer.exe Thermometer.exe is started automatically from c:emu8086devices.
- 8. #make-bin# Fawad Masood Ktk Here Your Program Will Change Into Binary Form And In First 2 Instructions we are Supposed To Move The Data From CS To DS i.e Set Data Segment To Code Segment Instructions Are : Mov ax,cs ; Move Data From CS to AX Mov ds,ax ; The Move It To DS Because It Is Not possible To move Data from CS To DS Directly We Use Accumulator For It.
- 9. Use For Port In Next Instruction Here We Used Instruction i.e In al,125 This Means That On the Port 125 There Is Direct Data will Go to The Accumulator Rather Then Accumulator We can’t Use any Other Temporary Registers Because This Is The Orignal Format for input Output Instruction
- 10. Use Of Compare Fawad Masood Ktk Cmp al,60 Now That Data Which Came From the Port 125 to Al Is Compared With 60 ,That data Will Be Either Less Or Greater Then 60 On port 125 Note: 125 Port is Use For The Temperature Measure
- 11. Use Of JL Command Fawad Masood Ktk Jl Low Low: If The Value Of al Is Less The 60 This Means That it will go to Low Loop Where It is defined As: Mov al,1 ; Move 1 in Al (1=ON) Out 127,al AL data Put It into Port 127 and The Heater Get ON
- 12. NOTE Fawad Masood Ktk 127 Port Is Flame Port 125 Port Is For Temperature Measure Now Last Instruction Is : Jmp Ok
- 13. Again Compare Command Cmp al,80 This Means If The Value In Al Is equal To 80 or Less The 80 Then Go To Next Instruction Jle ok Jg High ; Jump Greater To High Where High: Mov Al,0 (Move 0 To Al) Out 127,al >> Put The Value in Port 127
- 14. Thermometer Fawad Masood Ktk The Heater Turned Off OK: Jmp start >>> Endless Loop
- 15. Thank You Fawad Masood Ktk
