This workspace collects field notes, experiments, and reference material about ESP32 analog-to-digital conversion (ADC) in continuous mode. The repo is organized so you can jump straight to the documentation you need or to a ready-to-build PlatformIO example.

• adc_continuous.md – overview of continuous ADC capture and configuration hints.
• ADC_dma*.md – several French/English drafts describing DMA-driven ADC, buffer limits, and the latest findings.
• iir_filter*.md – notes on applying IIR filtering to ADC streams (both EN/FR versions).
• parameters_opt_limits.md – practical parameter limits observed during testing.
• dma_limits.md – measured DMA throughput ceilings and troubleshooting tips.

Each subfolder is a standalone PlatformIO project targeting ESP32 boards:

• AdcContinuous – minimal continuous ADC capture sketch.
• AdcContinuousAvg – continuous capture with moving-average post-processing.
• AdcContinuousRms – continuous capture with RMS computation.

Mirror copies of AdcContinuousAvg and AdcContinuousRms exist at the repo root for quick opening in VS Code when the examples/ workspace is already in use.

1. Install PlatformIO IDE or CLI.
2. Open any project folder (for example examples/AdcContinuousAvg).
3. Build and upload with platformio run -t upload.

Feel free to document additional experiments, especially around DMA tuning, filtering strategies, or calibration techniques. Keep notes concise so they remain easy to reference during development.
