Tracie

Version 1.0.0-alpha · in Tinkerie 1.5.2-alphaAlpha

See what your board is saying, and the signals on its wires.

In plain words

When your Arduino or ESP32 prints messages, Tracie shows them, and turns any numbers into live graphs automatically. With a cheap 8-channel logic analyser it also records the digital signals on your wires and decodes them into readable bytes.

You'll need: A board on USB, or a cheap logic analyser (demo included).

Tracie
Serial: the demo board's messages, plotted live.
Your first five minutes

Try this first

  1. Try the DEMO board

    Pick DEMO in the port list and press Connect. No hardware needed.

  2. Watch the plotter

    Lines like temp:21.5,hum:40 are graphed by themselves.

  3. Send a command

    Type at the bottom, or use the quick buttons like LED on.

  4. Try Logic

    The Logic tab has a demo signal generator with UART, I²C, SPI and PWM.

Everything it does

Features

Serial monitor

Better than the Arduino one.

  • Ports show each board's USB chip (Arduino, ESP32, Pico, CH340, CP210x, FTDI…)
  • Any baud rate, plus DTR/RTS and a Reset board button
  • Reconnects by itself when boards like the ESP32-S3 and Pico reset
  • Timestamps, ESP-IDF colours, search and command history
  • Hex view, quick command buttons and CSV logging

Live plotter

Graphs from plain printed numbers.

  • Prints like temp:21.5,hum:40 or 1.2 3.4 5.6 are graphed automatically
  • Shared or stacked axes, windows from 5 seconds to 5 minutes

Logic analyser

For the cheap 24 MHz 8-channel analysers.

  • Sample rates from 20 kHz to 24 MHz, up to 100 million samples
  • Triggers on high, low, rising, falling or any edge
  • Decoders for UART, I²C and SPI, with a searchable list
  • Cursors and measurements: frequency, period, duty cycle
  • Export to VCD (PulseView, GTKWave), CSV or PNG

One timeline

Everything lines up.

  • Serial lines, plotted values and logic channels on one zoomable timeline
  • Logic captures show the serial messages alongside
Before you start

Good to know

Logic analysers need a one-time setup: a USB driver on Windows (Zadig) and the free fx2lafw firmware, which Tracie finds automatically if PulseView is installed. On Linux and Raspberry Pi, run install-usb.sh once instead.
