# DAQiFi

This MCP server links AI agents directly to DAQiFi Nyquist hardware. It lets you monitor sensor streams and configure outputs using plain conversation.

## What it does

The server exposes DAQiFi Nyquist 1 and Nyquist 3 hardware to MCP-compatible assistants. The model discovers boards over WiFi or USB, configures individual analog channels, and sets streaming frequencies without desktop software.

Under the hood, it relies on the cross-platform .NET runtime. Agents can toggle digital I/O pins, set PWM duty cycles, trigger analog outputs, and capture session telemetry to an SD card. Logged data transfers back as CSV files inside the chat interface.

Physical Nyquist hardware is mandatory. WiFi retrieval for SD card files requires firmware 3.7.0 or higher. Starting SD card logging is restricted to USB or serial connections.

## Install

### Claude Code (native platform)

**Install**
- The MCP registry has no launch command for it: see the repository README

## When to use it
- Detect DAQiFi Nyquist hardware connected via WiFi or USB
- Stream decoded analog sensor readings at custom sample rates
- Drive digital I/O pins and configure PWM duty cycles
- Retrieve logged telemetry files from the SD card as CSV

## Example prompts
- Scan the local network for DAQiFi devices and display open channels
- Enable analog channel 0 at 100 Hz and stream live readings
- Set the PWM duty cycle on pin 2 and log samples to the SD card
