This project contains a collection of code examples for the 8051 microcontroller, compiled with the SDCC compiler.

The project is organized into individual example directories, each containing its own source code and a README file with specific details.

• blink/: A simple example to blink a single LED.
• led-pattern/: A more advanced example demonstrating several patterns on 8 LEDs.

This project is developed and tested on a Linux-based operating system. The Makefile and shell commands are tailored for a Unix-like environment.

Required Tools:

• make
• sdcc (Small Device C Compiler)
• avrdude

The build system includes a check for sdcc and provides installation instructions for Debian/Ubuntu-based distributions.

This project uses a hierarchical build system powered by make. You can either build all examples at once from the root directory, or manage each example individually from its own subdirectory.

• Build All Examples:

  make all

• Clean All Examples:

  make clean

• Flash a Specific Example: You must provide the EXAMPLE variable.

  make flash EXAMPLE=blink
  make flash EXAMPLE=led-pattern

You can also cd into an example's directory and run commands that apply only to that example.

cd blink
make all          # Build just the blink example
make flash        # Flash just the blink example
make clean        # Clean just the blink example

All examples are configured to use Port 2 (P2) of the 8051 microcontroller for output.
