$XPS\Micro$ XPS\Micro 58b386b012 Implementiere WiFi-Integration und Projektverbesserungen

- WiFi-Aktivierung für A/B-Test (bootCount ungerade = WiFi ON, gerade = WiFi OFF)
- Zyklusende nach TOTAL_CYCLES*2 Boots implementiert
- SERIAL_DEBUG-Guards für alle Debug-Ausgaben hinzugefügt
- Secrets-Schutz: config.h in .gitignore, config_example.h als Template
- Funktionsfehler behoben: esp_reset_cause → esp_reset_reason
- Dokumentation aktualisiert (README, Info.md, CLAUDE.md)
- USB-Anforderungen für Upload und Serial Monitor dokumentiert

Raw Blame History

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

ESP32-C3 firmware for measuring power consumption across different sleep states using a PowerProfiler Kit II. The firmware cycles between active periods (5s, LED on) and deep sleep (30s, minimal power), with optional WiFi enabling for A/B testing.

Build & Development

All commands use PlatformIO. Board: esp32-c3-devkitm-1, Framework: Arduino

# Build firmware
pio run -e esp32-c3-devkitm-1

# Upload to device
pio run -e esp32-c3-devkitm-1 -t upload

# Monitor serial output (115200 baud)
pio device monitor -b 115200

# Clean build artifacts
pio run -e esp32-c3-devkitm-1 -t clean

Architecture

Single-purpose firmware with execution entirely in setup() — loop() is never reached due to esp_deep_sleep_start().

Key design pattern: RTC memory persistence via RTC_DATA_ATTR variables (e.g., bootCount) survive deep sleep resets, allowing multi-cycle experiments without external state.

Control flow:

Boot → increment RTC counter
Report reset reason and cycle status
LED on for ACTIVE_DURATION_MS
Configure timer wakeup for SLEEP_DURATION_S
Enter deep sleep (CPU halts, only RTC timer remains)
Auto-wakeup via RTC timer → restart from boot

Configuration (all in include/config.h):

SLEEP_DURATION_S: Deep sleep interval
ACTIVE_DURATION_MS: Time spent awake (measurement window)
TOTAL_CYCLES: Number of complete cycles to run
WIFI_ENABLED_CYCLE_1/2: Alternating WiFi on/off for A/B measurement comparison

Serial debug output includes reset reason code (5 = DEEPSLEEP_RESET) for timing validation and cycle tracking.

Power Measurement Setup

Device connects via PowerProfiler Kit II (supplies power + measures current). Use nRF Power Profiler app on host to record measurements. Firmware will cycle autonomously once uploaded; each boot generates serial output for correlation with profiler traces.
