ESP32-S3 Low-Level Register Coding Examples

This GitHub repository contains a collection of low-level register coding examples for the ESP32-S3 microcontroller. These examples demonstrate how to interact directly with the hardware registers of the ESP32-S3 to perform various tasks, such as configuring GPIO pins, setting up timers, and controlling peripherals.

Introduction

The ESP32-S3 is a highly integrated, low-power, and secure Wi-Fi and Bluetooth SoC (System on Chip) designed for a wide range of IoT applications. While the Espressif IDF (IoT Development Framework) provides a high-level API for developing applications on the ESP32-S3, sometimes you may need to access hardware registers directly for fine-grained control or to implement specific functionality.

This repository serves as a resource for ESP32-S3 developers looking to work with low-level hardware registers. Each example demonstrates how to perform a particular task by configuring the relevant registers.

Getting Started

To get started with these examples, follow these steps:

1. Clone this repository to your local development environment:

   git clone https://github.com/nikhil-robinson/esp-idf-register-level.git

2. Set up the ESP-IDF development environment according to the official ESP-IDF documentation.

3. Navigate to the specific example directory you're interested in.

4. Follow the README or code comments in that directory to understand how the low-level register coding is used to achieve a specific task.

Examples

Here are some examples of tasks covered in this repository:

1. GPIO Configuration - Demonstrates how to configure GPIO pins for input or output.

2. UART Communication - Illustrates low-level UART communication using registers.

Please explore the examples directory for more low-level coding examples.
