How to Use RP2040 OpenAI Example

Step 1: Prepare Software

1. The following Python IDE program is required for test, download and install from below links.

Thonny

2. Deploying firmware to the device. you can use the below firmware.

FW for RP2040_OpenAI_Micropython

If you need a detailed explanation of firmware and Thonny setup, please refer to the video below.

Raspberry Pi Pico MicroPython Guide

Step 2: Prepare hardware

1. Combine WIZnet Ethernet HAT with Raspberry Pi Pico.
2. Connect ethernet cable to Ethernet HAT ethernet port.
3. Connect Raspberry Pi Pico to desktop or laptop using 5 pin micro USB cable.

If you use W5100S-EVB-Pico, you can skip '1. Combine...'

Step 3: Setup Example

To test the Open AI example, minor settings shall be done in code.

1. Check COMport in Device Manager and then open Thonny Python IDE.

2. Setup SPI and Reset pin in chat_with_openai.py or send_prompt.py file.

If you are not using the WIZnet PICO Board, please adjust the SPI pin configuration according to your hardware setup.

spi=SPI(0,2_000_000, mosi=Pin(19),miso=Pin(16),sck=Pin(18))

3. Enter OpenAI information(version, API key) into the chatGPT.py file.

If you have not generated an API key, please generate one on the following site https://platform.openai.com/account/api-keys

    api_key = "insert your API-KEY"
    chatgpt_url = "https://api.openai.com/v1/chat/completions"
    chatgpt_ver= "gpt-3.5-turbo"

Step 4: Upload and Run

1. send prompt to openAI

The function 'send_prompt_to_chatGPT' sends the prompt to openAI and receives a response from the model. If the response is successful, the generated text is printed serial program.

Enter the prompt as a parameter for the [send_prompt_to_chatGPT] function.

    send_prompt_to_chatGPT("Hello")

2. chat with openAI

The function 'chat_with_chatGPT' enables communication with the chatGPT model using the OpenAI API via a serial program. It user enter a message and sends it to OpenAI as a prompt, then prints the response.

The default exit command is ">exit". To modify the exit command, please modify the relevant section in the chatGPT.py file.

    end_command= ">exit"
