Hardware Instruments

Neural Inverse integrates with external hardware instruments for signal capture, power measurement, and protocol analysis.

Logic Analyzer

Supported Hardware

Protocol Decoders

Saleae (23 protocols): uart, spi, i2c, can, lin, i2s, jtag, swd, manchester, modbus, 1-wire, parallel, async-serial, biss-c, hdlc, hdmi-cec, i2s-pcm, jtag-raw, mdio, midi, ps2, smbus, usb-ll

Digilent (11 protocols): uart, spi, i2c, can, lin, i2s, manchester, modbus, 1-wire, parallel, async-serial

Usage

> fw_la_capture channels=0,1,2,3 duration=1s sampleRate=24MHz

Captures digital signals on specified channels.

> fw_la_decode spi captureId=abc123

Decodes a captured signal using the specified protocol.

> fw_la_trigger channel=0 edge=rising

Arms a trigger condition for the next capture.

> fw_la_export captureId=abc123 format=csv

Exports captured data.

Storage

Captures are stored in .inverse/captures/<captureId>/.

Power Analyzer

Capabilities

• Voltage rail measurement
• Current measurement (shunt-based)
• Power calculation (RMS, peak, average)
• Boot profiling (power consumption during startup)
• Per-function power attribution (with correlated debug trace)

Usage

> fw_pa_measure duration=5s

Measures power consumption for a duration.

> fw_pa_set_voltage 3.3

Sets the voltage rail for measurement reference.

> fw_pa_record duration=10s label="deep_sleep_test"

Records a power profile with a label.

> fw_pa_profile_boot

Profiles power consumption during MCU boot sequence.

> fw_pa_trigger event=gpio_high channel=PA5

Triggers power measurement on a GPIO event.

Oscilloscope

Protocol

Uses SCPI (Standard Commands for Programmable Instruments) for universal oscilloscope compatibility.

Usage

> fw_scope_discover

Discovers connected oscilloscopes on the network/USB.

> fw_scope_capture channel=1 duration=10ms

Captures an analog waveform.

> fw_scope_measure channel=1 type=frequency

Measures signal properties (frequency, amplitude, rise time, etc.).

> fw_scope_rail_check voltage=3.3 tolerance=5%

Checks if a power rail is within tolerance.

> fw_scope_scpi "*IDN?"

Sends raw SCPI commands for advanced control.

> fw_scope_screenshot

Captures the oscilloscope display.

Coordinated Capture

Synchronize multiple instruments for correlated measurement:

> fw_capture_all logic=0,1,2,3 power=true serial=true duration=2s

Captures simultaneously from logic analyzer, power analyzer, and serial monitor. All data is time-correlated for analysis.

> fw_correlate_power_logic captureId=abc123

Correlates power consumption with digital signal activity.
