# LoRa HelloWorld Project
# ESP32 Static IP Project
Welcome to the **LoRa HelloWorld** project! This is a simple project designed to demonstrate basic usage of the i2C interface using a ssd1306 display. The Lora model used was a Lora32 T3 v1.6.1
Welcome to the **ESP32 Static IP** project! This is a working example of how to configure a static IP using `non_std`.
## Features
- Prints "Hello, World!" on a ssd1306 display.
- Connect to your static IP and serve an image.
- Tested on a Lora32 T3 v1.6.1.
## Requirements
- espup installed
- rust installed
- [espup](https://github.com/esp-rs/espup) installed
- [Rust](https://www.rust-lang.org/) installed
## Installation
1. Clone the repository:
```bash
git clone https://github.com/bibble235/lora-helloworld.git
git clone https://github.com/bibble235/esp32-static-ip.git
```
2. Navigate to the project directory:
```bash
cd lora-helloworld
cd esp32-static-ip
```
3. Set the environment variables for your static IP and Wi-Fi credentials. Remember to escape special characters like `@` and `$`:
```bash
export SSID="MyWifi"
export PASSWORD="MyPassword"
export STATIC_IP="10.1.2.3"
export GATEWAY_IP="10.1.1.99"
```
## Usage
Run the application with the following command:
Build and run the application with the following commands:
