I will use '**WizFi360_arduino_library**' provided by WIZnet. - [WizFi360_arduino_library](https://github.com/Wiznet/WizFi360_arduino_library) And for the **DALL-E basic example using OpenAI API**, the example below was used. - [WizFi360_arduino_library/examples/OpenAIDallEBasic](https://github.com/Wiznet/WizFi360_arduino_library/tree/openai/examples/OpenAIDallEBasic) ### **1. Development environment Preparation** To test the WizFi360 Arduino library & DALL-E basic example using OpenAI API, the development environment must be configured to use Arduino platform. Please note that in this guide DALL-E basic example using OpenAI API was configured and tested using **Arduino IDE** in **Windows** environment. Before starting, download and install the Arduino IDE from the link below. - [Arduino IDE](https://www.arduino.cc/en/software) Additionally, if you are using WizFi360-EVB-Pico, minor settings are required in the Arduino IDE. WizFi360-EVB-Pico is an development board based on RP2040, and you need to add a package to use the development board based on RP2040. ① Run the **Arduino IDE** ② Open **Preferences** You can open it through 'File → Preferences' in the menu bar of Arduino IDE. ③ Add next link to **Additional Boards Manager URLs** ```plaintext https://github.com/earlephilhower/arduino-pico/releases/download/global/package_rp2040_index.json ``` ![Add Boards Manager URLs](https://hackster.imgix.net/uploads/attachments/1631785/image_6Npg4yHfkx.png?auto=compress%2Cformat&w=740&h=555&fit=max) Add Boards Manager URLs ④ Open **Boards Manager...** Open it via 'Tool → Board: "" → Boards Manager...' ⑤ Install **board support package** Search and install **Earle F. Philhower's Raspberry Pico/RP2040** board support package. ![Install board support package](https://hackster.imgix.net/uploads/attachments/1631786/image_A42o4sjspJ.png?auto=compress%2Cformat&w=740&h=555&fit=max) Install board support package **2. H/W PreparationWizFi360-EVB-Pico** is a development board that is built on high-performance, low-price MCU **RP2040** and adds Wi-Fi connectivity using **WizFi360**. More details can be found at below link: - [WizFi360-EVB-Pico](https://docs.wiznet.io/Product/Open-Source-Hardware/wizfi360-evb-pico) WizFi360-EVB-Pico is pin compatible to Raspberry Pi Pico. But keep in mind that pins GPIO4 ~ GPIO7 / GPIO20 are used for UART communication / reset between RP2040 and WizFi360. ![WizFi360-EVB-Pico pinout](https://hackster.imgix.net/uploads/attachments/1631787/image_OJKNPIqht4.png?auto=compress%2Cformat&w=740&h=555&fit=max) WizFi360-EVB-Pico pinout Follow the steps below to firmware upload and run. ① Connect WizFi360-EVB-Pico to desktop or laptop using 5 pin micro USB cable. ### **3. S/W Preparation** The following serial terminal program is required for example test, download and install from below link. - [Tera Term](https://osdn.net/projects/ttssh2/releases/) ### **4. Example Settings** This section will guide through testing the DALL-E basic example using OpenAI API with WizFi360-EVB-Pico. ① Setup **Sketchbook location** Setup the Sketchbook location according to the location of the downloaded 'WizFi360_arduino_library'. !['WizFi360_arduino_library' location](https://hackster.imgix.net/uploads/attachments/1631788/image_atKwrO5aGC.png?auto=compress%2Cformat&w=740&h=555&fit=max) 'WizFi360_arduino_library' location ![Setup Sketchbook location](https://hackster.imgix.net/uploads/attachments/1631789/image_veatkjbffT.png?auto=compress%2Cformat&w=740&h=555&fit=max) Setup Sketchbook location ② Open **example** You can open examples through 'File → Examples → WizFi360'. ![Open example](https://hackster.imgix.net/uploads/attachments/1631797/image_1fpKZThF4P.png?auto=compress%2Cformat&w=740&h=555&fit=max) Open example ③ Select **device** Select WizFi360-EVB-Pico. ![Select device](https://hackster.imgix.net/uploads/attachments/1631800/image_WCwwpMGAZP.png?auto=compress%2Cformat&w=740&h=555&fit=max) Select device ④ Select **COM port** Select the COM port of WizFi360-EVB-Pico. ![Select COM port](https://hackster.imgix.net/uploads/attachments/1631801/image_pKF0TWDVOB.png?auto=compress%2Cformat&w=740&h=555&fit=max) Select COM port ⑤ Setup **device setting** according to device you use Serial port configuration is different depending on the device used. - Arduino Mega 2560 : ARDUINO_MEGA_2560 - WizFi360-EVB-Pico : **WIZFI360_EVB_PICO** ```plaintext // setup according to the device you use #define WIZFI360_EVB_PICO ``` ⑥ Setup **Wi-Fi configuration** ```plaintext /* Wi-Fi info */ char ssid[] = "wiznet"; // your network SSID (name) char pass[] = "0123456789"; // your network password ``` ⑦ Setup **OpenAI API key** ```plaintext client.println("Authorization: Bearer sk-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"); // your OpenAI API key ``` ### **5. Example Build & Upload** ① After completing the configuration, click **Verify** button. ![Click Verify button](https://hackster.imgix.net/uploads/attachments/1631802/image_aRqqPpMc0S.png?auto=compress%2Cformat&w=740&h=555&fit=max) Click Verify button ② When the build is completed, click **Upload** button to upload the firmware to the WizFi360-EVB-Pico. ![Click Upload button](https://hackster.imgix.net/uploads/attachments/1631803/image_GOU6PVVTG7.png?auto=compress%2Cformat&w=740&h=555&fit=max) Click Upload button **6.
