Introduction

HMCLS (High-density Multi-Channel recording System) is a platform for real-time neural recording. It pairs a dedicated embedded device with a cross-platform desktop application.

System Overview

Component	Description
HMCLS device	A multi-channel neural recording system that handles acquisition, spike detection, and user script execution.
hmcls-app (Tauri)	Desktop application (Windows/macOS/Linux) that connects to the device over Ethernet/UDP, provides the visual block programming studio, and displays real-time data.

Key Capabilities

What HMCLS can do

• Acquisition — up to 32 channels simultaneously (16 or 32, depending on the headstage)
• Block programming — visual Studio panel compiles programs to firmware bytecode
• Python scripting — .hom Python scripts can send UDP commands and react to data streams, enabling automated experiments and custom workflows
• Multi-board coordination — multiple devices collaborate via UDP network commands
• Real-time visualization — signal viewer, raster, heatmap, and STA panels
