## Overview

This repository contains two 8051 Assembly course experiments: flashing an LED and reading a DIP switch. The documented workflow is to compile an `.a51` program into a `.hex` image, open its Proteus project, load the image onto an 8051, and simulate the behavior. The README describes this workflow generally; no source excerpts were provided, so experiment-specific code behavior and wiring are not mapped.

Main entry points: [`01_Flash-LED/Flash-LED.a51`](https://github.com/shangyi7/nkust_1151_0886_embedded_system/blob/master/01_Flash-LED/Flash-LED.a51) (LED Assembly), [`02_DIP-switch/DIP-switch.a51`](https://github.com/shangyi7/nkust_1151_0886_embedded_system/blob/master/02_DIP-switch/DIP-switch.a51) (DIP Assembly), [`01_Flash-LED/Flash-LED.hex`](https://github.com/shangyi7/nkust_1151_0886_embedded_system/blob/master/01_Flash-LED/Flash-LED.hex) (LED Firmware), [`02_DIP-switch/DIP-switch.hex`](https://github.com/shangyi7/nkust_1151_0886_embedded_system/blob/master/02_DIP-switch/DIP-switch.hex) (DIP Firmware)
