Overview

This repository provides an easy-to-use ADC module for the PIC16F877A microcontroller. With this code, you can turn raw analog signals into digital data. This makes it perfect for reading values from sensors like temperature and light sensors. You can find the latest release here.

Features

• Simple Integration: Designed for embedded developers.
• Modular Code: Easily adapt the code for various applications.
• Reliable Results: Get accurate readings without the hassle of complex datasheets.
• Support for Multiple Sensors: Works with different analog input devices.

Getting Started

To get started, clone the repository to your local machine. Ensure you have the necessary tools to program the PIC16F877A microcontroller.

Prerequisites

• PIC16F877A microcontroller
• MPLAB X IDE
• XC8 Compiler
• Basic understanding of embedded programming

Installation

1. Clone the repository:

   git clone https://github.com/danny2017aqp/ADC_in_PIC16F877A.git

2. Open the project in MPLAB X IDE.
3. Compile the code using the XC8 compiler.
4. Upload the code to your PIC16F877A microcontroller.

Usage

After installation, you can start using the ADC module. Include the library in your main program file. The library handles the initialization and reading of analog inputs.

Example Code

#include "adc.h"

void main() {
    ADC_Init(); // Initialize ADC
    int value = ADC_Read(0); // Read from channel 0
    // Process the value as needed
}

Code Examples

Here are some examples to help you get started:

Reading from a Temperature Sensor

#include "adc.h"

void main() {
    ADC_Init();
    int tempValue = ADC_Read(0); // Assume temperature sensor is on channel 0
    // Convert ADC value to temperature
}

Reading from a Light Sensor

#include "adc.h"

void main() {
    ADC_Init();
    int lightValue = ADC_Read(1); // Assume light sensor is on channel 1
    // Process light value
}

Supported Analog Sensors

• Temperature Sensors: LM35, DS18B20
• Light Sensors: LDR, Photoresistor
• Other Sensors: Potentiometers, Hall Effect Sensors

Library Structure

The library consists of the following files:

• adc.h: Header file containing function declarations.
• adc.c: Source file implementing the ADC functions.
• config.h: Configuration settings for the ADC module.

Functions

• void ADC_Init(): Initializes the ADC module.
• int ADC_Read(int channel): Reads the analog value from the specified channel.
