Inquestra communicates directly with microcontrollers and analog front-ends via the native W3C Web Serial API. Stream continuous multi-channel biopotential, hemodynamic, and force transducer signals directly into your experimental notebook buffer with zero intermediate daemons.
Traditional biomedical DAQ setups rely on ad-hoc Python listeners, proprietary National Instruments runtime drivers, or custom C++ daemons writing loose CSV files to workstation desktops. Inquestra replaces this entire fragile chain with browser-native Web Serial communication.
Connects directly to Silicon Labs CP2102, WCH CH340, FTDI FT232R, and native microcontroller USB-OTG controllers without requiring administrative driver installs or kernel extensions.
Raw byte parsing and packet validation execute inside a dedicated HTML5 Web Worker. High-speed 1 kHz sampling streams never cause UI frame drops or notebook interface stutter.
Supports standard laboratory baud rates from 9,600 up to 921,600 baud with hardware flow control (RTS/CTS), enabling synchronous acquisition across multiple high-gain analog sensor channels.
Every microcontroller firmware driver is benchmarked for packet stability, buffer overrun resistance, and clock drift.
