Prerequisites

HEX File: Make sure you have the compiled HEX file of your program. This file contains the machine code that needs to be loaded into the microcontroller.
Programmer: You need a programmer that supports the 8051 microcontroller. Common programmers include USB programmers or standalone programmers.
Connection: Connect the programmer to your computer and to the appropriate pins on the 8051 microcontroller.

Please refer to the documentation of your specific programmer and microcontroller for detailed instructions, as the process may vary depending on the manufacturer and model.

Steps to follow

Install Programmer Software

Install the software that comes with your programmer. This software allows you to select the HEX file and transfer it to the microcontroller.

Connect Programmer to Computer

Connect your programmer to the computer using USB or any other interface supported by the programmer.

Connect Programmer to 8051 Microcontroller

Connect the appropriate pins on the programmer to the corresponding pins on the 8051 microcontroller. Make sure to connect Vcc, GND, MOSI, MISO, SCK, and any other required pins.

Power Up the System

Power up the 8051 microcontroller and ensure that the connections between the programmer and the microcontroller are correct.

Open Programmer Software

Open the software that came with your programmer. It might have options for selecting the target microcontroller and loading the HEX file.

Select HEX File

Locate and select the HEX file of your program using the programmer software.

Configure Programmer Settings

Set the programmer settings, such as the target microcontroller type, communication settings, and any other relevant parameters, as per the above circuit diagram

Program the Microcontroller

Initiate the programming process using the software. The programmer will transfer the HEX file data to the microcontroller’s memory.

Open the ProgISP Application

Select the correct chip at the drop-down option in the Select Chip from the PROGRAM menu tab.

Connect your ISP programmer with Programmer’s Machine

Check selected chip is successfully connected with ProgISP software using click RD button in PROGRAM menu tab (After click RD you will get the following details in status section)
Note : This Status means you are connected your micro-controller and Programmer with ProgIPS Software Successfully

If the micro-controller and programmer are not connected with ProgISP software tools means you will get a error log

Click Load Flash from File menu tab

Open the HEX file folder then select the HEX file and Click Open Button

If the HEX file is successfully loaded you will can see like a status

Click Auto from the PROGRAM (Programming Section)

Done! You can see the status like below image

Verify and Test

After programming is complete, the software may provide an option to verify the programmed data. Perform any necessary tests to ensure that the program has been loaded correctly.

Disconnect and Run

Once the programming and verification are successful, disconnect the programmer from the microcontroller. Power cycle the microcontroller, and it should now run the program you loaded.
