ESP32_Process_Big_Data_Process

This Arduino sketch for ESP32 is designed for 16MB ESP32 boards(Can also work with 4MB/8MB ESP with default partition scheme, the storage of 27% will not be used), utilizing the default partition scheme of 3MB for APP and 9.9MB for FATFS. The code facilitates the retrieval and processing of fingerprint data stored on a server. The data file it downloads is 3MB, containing information for 750 IDs. This version is an updated iteration of a previous project, where data was manually uploaded to FATFS using tools in the Arduino IDE.

Features

• WiFi connection setup.
• Data download from URLs.(GitHub file raw data)
• FFat file system usage.
• Parsing and processing of downloaded fingerprint data.
• User input for finding specific IDs.
• Serial communication for debugging.

Getting Started

1. WiFi Configuration:

   • Replace SSID and PASSWORD with your WiFi credentials.

2. URLs for Fingerprint Data:

   • Modify the FileUrl array with the URLs containing fingerprint data.

3. ESP32 Configuration:

   • Ensure that you are using a 16MB ESP32 and the default partition scheme of 3MB APP / 9.9MB FATFS

4. Upload to ESP32:

   • Use the Arduino IDE or your preferred method to upload the sketch to your ESP32.

5. Serial Communication:

   • Open the Serial Monitor to view debugging information and interact with the code.

Data File Details

• File Size: 3MB
• Number of IDs: 750
