W25Q64 Driver for ESP-IDF

Introduction

The W25Q64 is a 64M-bit (8M-byte) serial flash memory that provides a storage solution for systems with limited space, pins, and power. It is commonly used in embedded systems for data storage due to its high performance and reliability.

This project provides a driver for interfacing the W25Q64 flash memory with the ESP32 using the ESP-IDF framework. The driver handles the communication between the ESP32 and the W25Q64, allowing for operations such as reading, writing, and erasing data.

Getting Started

1. Setup ESP-IDF: Follow the ESP-IDF setup guide to configure your development environment.

2. Clone the Repository: Clone this repository to your local machine.

3. Build the Project: Navigate to the project directory and run idf.py build to build the project.

4. Flash the Project: Use idf.py flash to upload the firmware to your ESP32 board.

5. Monitor the Output: Use idf.py monitor to view the output from the ESP32.

6. Looking for the main application which demonstrates basic operations with the W25Q64 flash memory. Refer to the code in the main/ directory for examples on how to use the driver.
