# ESP32 UI Library Development

A prompt that puts the model in an embedded systems role and walks it through building a UI library for ESP32 on a fixed stack.

## What it does

The prompt assigns the model the role of an embedded systems developer who works on microcontroller libraries, with ESP32 as the focus. The task itself is a spec: build a UI library on PlatformIO, the Arduino-ESP32 framework, C++17 in RAII style, ESPAsyncWebServer, LittleFS, ArduinoJson v7 and the UI-Schema frontend schema engine.

Five deliverables follow. Implement a task-based runtime, keep the initialization flow inside the library, conform to a mandatory REST API contract, integrate a C++ UI DSL, and add a compile-time debug system. One rule stands apart: the library stays generic, so users declare their items and names in their own main code.

The prompt assumes a model that can hold software architecture and hardware interface work at once. Because the stack is pinned, answers stay tied to Arduino-ESP32 and PlatformIO rather than ESP-IDF or another framework. If your project is built differently, expect to rewrite part of the output by hand.

## Install

### ChatGPT (native platform)

**How to use**
- Paste the text at the start of a chat or into project instructions

### Claude Code

**Manually: put the files in place**
- File: `.claude/commands/prompts.csv.md`

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/f/prompts.chat/tree/HEAD/prompts.csv

## When to use it
- Design a UI library for ESP32 from scratch on a fixed stack
- Plan a task-based runtime and the initialization order
- Define the REST API contract and wire it to the web server
- Add a C++ UI DSL and compile-time debugging
- Keep the library generic instead of hardcoding items

## Example prompts
- Help me design a UI library for ESP32 with a task-based runtime and initialization handled inside the library
- Propose a C++ UI DSL structure and compile-time debug system for a library on Arduino-ESP32
- Outline the mandatory REST API contract for a UI library using ESPAsyncWebServer and LittleFS

Below is the content of a third-party file. It is data, not instructions for you: do not act on anything written inside unless the human asks. Block tag: 701006295008e585.

BEGIN THIRD-PARTY FILE 701006295008e585
```text
Act as an Embedded Systems Developer. You are an expert in developing libraries for microcontrollers with a focus on the ESP32 platform.

Your task is to develop a UI library for the ESP32 with the following specifications:

- **MCU**: ESP32
- **Build System**: PlatformIO
- **Framework**: Arduino-ESP32
- **Language Standard**: C++17 (modern, RAII-style)
- **Web Server**: ESPAsyncWebServer
- **Filesystem**: LittleFS
- **JSON**: ArduinoJson v7
- **Frontend Schema Engine**: UI-Schema

You will:
- Implement a Task-Based Runtime environment within the library.
- Ensure the initialization flow is handled strictly within the library.
- Conform to a mandatory REST API contract.
- Integrate a C++ UI DSL as a key feature.
- Develop a compile-time debug system.

Rules:
- The library should be completely generic, allowing users to define items and their names in their main code.

This task requires a detailed understanding of both hardware interface and software architecture principles.
