zx2xberry

A Python package that enables users to control their XBerry Pi devices using a ZX Spectrum+ keyboard by translating keypresses into structured commands.

Features

• Translates ZX Spectrum+ keyboard keypresses into structured commands for XBerry Pi devices
• Uses LLM7 by default (via langchain_llm7)
• Supports custom LLM instances from LangChain
• Free tier of LLM7 has sufficient rate limits for most use cases

Installation

pip install zx2xberry

Usage

Basic Usage

from zx2xberry import zx2xberry

response = zx2xberry("user input describing keypresses")

Using a Custom LLM

You can use any LLM compatible with LangChain. Here are examples with different LLMs:

OpenAI

from langchain_openai import ChatOpenAI
from zx2xberry import zx2xberry

llm = ChatOpenAI()
response = zx2xberry("user input", llm=llm)

Anthropic

from langchain_anthropic import ChatAnthropic
from zx2xberry import zx2xberry

llm = ChatAnthropic()
response = zx2xberry("user input", llm=llm)

Google

from langchain_google_genai import ChatGoogleGenerativeAI
from zx2xberry import zx2xberry

llm = ChatGoogleGenerativeAI()
response = zx2xberry("user input", llm=llm)

Using a Custom API Key

You can provide your own API key for LLM7 either via environment variable or directly:

from zx2xberry import zx2xberry

# Via environment variable
import os
os.environ["LLM7_API_KEY"] = "your_api_key"
response = zx2xberry("user input")

# Directly
response = zx2xberry("user input", api_key="your_api_key")

Parameters

• user_input (str): The user input text to process
• llm (Optional[BaseChatModel]): The LangChain LLM instance to use. Defaults to ChatLLM7.
• api_key (Optional[str]): The API key for LLM7. If not provided, it will use the environment variable LLM7_API_KEY or the default LLM7 key.

Returns

A list of structured commands that the XBerry Pi can interpret and execute.

Getting an LLM7 API Key

You can get a free API key by registering at LLM7.
