Overview

Create / access SQLite3 database files using this library through SPIFFS / SD Cards.

For more information, please see https://github.com/siara-cc/esp32_arduino_sqlite3_lib

Installation

Install ESP-IDF sdk using instructions from https://docs.espressif.com/projects/esp-idf/en/latest/get-started/.

Unzip this project under esp-idf/components folder. Or if you are cloning the repository at https://github.com/espressif/esp-idf, add this repository as submodule using:

git submodule add https://github.com/siara-cc/esp32-idf-sqlite3 components/esp32-idf-sqlite3.

Using examples

1. Download [esp-idf-v3.1.1.zip](https://github.com/espressif/esp-idf/releases/download/v3.1.1/esp-idf-v3.1.1.zip) that includes submodules and unzip
2. cd esp-idf-v3.1.1, set path to xtensa-esp32-elf/bin and set IDF_PATH
3. git submodule add https://github.com/siara-cc/esp32-idf-sqlite3 components/esp32-idf-sqlite3
4. git submodule add https://github.com/siara-cc/esp32-idf-sqlite3-examples examples/esp32-idf-sqlite3-examples
5. cd examples/esp32-idf-sqlite3-examples/spiffs
6. make flash
7. To check output, use miniterm.py <device> 115200 and reset board

Information specific to ESP-IDF

To check out how this library works, please try the examples using:

git submodule add https://github.com/siara-cc/esp32-idf-sqlite3-examples examples/esp32-idf-sqlite3-examples

For instance, to check how Sqlite3 databases can be created on SPIFFS, naviate to the folder examples/esp32-idf-sqlite3-examples/spiffs and invoke make flash.

Many configurations specific to SQLite library have been set in the sdkconfig file, such as:

• Increasing stack size
• Setting SPIFFS partition information
• Partition size

The Flash size has been assumed as 4MB for SPIFFS example. Please change any of these configurations if necessary.
