ESP32 MicroSui Hardware Implementation

Introduction

This is the code for the hardware implementation of the ESP32 microcontroller. Specifically, in this software, we are using version C3 of the ESP32 microcontroller (ESP32-C3), however, this code is compatible with all versions of ESP32.

For this hardware implementation, PlatformIO was chosen as the development environment and firmware builder.

Getting Started

1. Install PlatformIO

PlatformIO is a VSCode extension. Install VSCode if you don't already have it.

2. Clone the Repository

git clone https://github.com/MicroSui/microsui-esp32.git

3. Open the Project in PlatformIO

Open the PlatformIO extension, click on Open in Quick Access, and select the project folder where you cloned it.

4. Check the Available Examples

Start your project from scratch, or begin with a reliable starting point by browsing the available examples.

5. Compile and Upload Firmware

Once you finish your project, compile and upload the firmware to the ESP32 by clicking Upload and Monitor in PlatformIO’s Project Tasks.

Available Examples

These are the available examples in this Hardware Implementation:

• signOfflineFromHexaPk – Generate an offline Sui signature from a fixed message using a hexadecimal private key.
• signOfflineFromBech32Pk – Generate an offline Sui signature from a fixed message using a Sui Bech32 private key.

Notes:

• If you want to use another version of ESP32 you simply need to change it to the version you want by modifying board = xxxxxxx (board = esp32-c3-devkitm-1 by default) in the /platformio.ini file in the root of the project.
