This project allows you to program an 8051 microcontroller using an Arduino as a programmer and a Python script to transmit .hex files over a serial connection.
- Program 8051 microcontrollers via serial interface.
- Use Arduino as a bridge programmer.
- Automatically erases and flashes the 8051 ROM.
- Supports most 8051-compatible chips (e.g., AT89S52, AT89C51).
- Python 3.x
- Arduino board (Uno, Nano, Mega, etc.)
- 8051 microcontroller with ISP support
- HEX file compiled for 8051
- USB connection between Arduino and PC
- Serial connection between Arduino and 8051
- Python
pyseriallibrary
Download and install Python from https://www.python.org.
Install the required serial library using pip:
pip install pyserial- Upload "Programming-8051.ino" to the arduino.
- Send hex file serially by the following:
python send_file.py (dir/hexfile.hex) (Serial Port i.e. COM3) (Baud Rate: 9600)
- An actuall command would look like this:
python send_file.py hexfile.hex COM3 9600
- After receieving the hex file, the arduino will erase the 8051 chip and flash the newly sent code into the 8051 ROM.
