TrueRNG Intention Test — GCP-style cumulative z-score viewer

This page shows the full Processing sketch for a TrueRNG-based serial hardware random number generator intention test, with optional fixed durations and a continuous run mode, plus a live GCP-style cumulative z-score graph.

Overview

What this sketch does

A TrueRNG-specific Processing sketch that reads hardware random bits over serial, bins them into time blocks, and plots a GCP-style cumulative z-score to explore intention-related departures from randomness.

Timed runs + Continuous

This sketch is designed for TrueRNG devices and:

Connects to a TrueRNG hardware random number generator exposed as a serial (USB CDC) port, reading bytes in real time.
Unpacks each byte into 8 bits and groups them into fixed-length “GCP-style” blocks (1 second per block by default).
For every block, counts the ones, computes a z-score for deviation from 50/50, and accumulates these into a cumulative z-score series.
Draws a live graph of cumulative z versus block index, with significance lines at ±1.96 (≈ p = 0.05).

The UI panel at the top lets you:

Choose a serial port for your TrueRNG, a goal (High / Medium / Low), and a run duration (1 min, 3 mins, 5 mins, or Continuous).
Use a single Start Run / Stop Run button to begin a test or stop it manually.

When a run ends (either by time limit or manual stop in continuous mode), the sketch:

High goal: HIT if final cumulative z ≥ +1.96.
Low goal: HIT if final cumulative z ≤ −1.96.
Medium goal: HIT if |final cumulative z| ≤ 1.0.

The outcome is shown as a HIT or MISS banner with the final cumulative z-score so you can compare multiple runs.
