What is Accordion Pilot?

Accordion Pilot is a Windows desktop application for interacting with, controlling, and testing Accordion hardware systems. It provides a graphical interface for all hardware operations.

Architecture

Accordion Pilot (Windows WPF)
  └── HTTP → AccordionQ2 WebApi (:5000) on Raspberry Pi

Installation & Launch

Run AccordionPilot.exe. The splash screen displays while the application initialises.

Connecting to a Device

Enter the device hostname or IP in the toolbar host field (e.g. agent64.local or 192.168.0.222)
Click Connect (or press Enter)
The status bar shows Connected when the WebApi and hardware manager are both reachable

Use the left-side navigation panel to switch views. Keyboard shortcuts for quick navigation:

Shortcut	View
Alt+1	Channels
Alt+2	Settings
Alt+3	Chart
Alt+4	Transactions
Alt+5	Log
Alt+6	PSUs
Alt+7	Cal Table
Ctrl+F	Open Find/Filter
F5	Refresh current view

Views

Channels

ap-channels.md

The primary view. Every hardware endpoint (GPIO, ADC, I2C, etc.) appears here as a row.

Grid columns: NetName · Alias · GroupName · ChannelType · Capability · Direction · Unit · Value · DeviceName

Key operations:

Read value — double-click a row, or enable polling for continuous refresh
Write value — right-click → Write, or use the editor panel
Filter — Ctrl+F; supports wildcard and regex
Sort — click column header; Shift+click for multi-column sort
Group — drag column header to the grouping panel
Alias file — load a .json alias file to display friendly names instead of net names

Bus Transactions

ap-transactions.md

Real-time monitor for all bus communications (I2C, SPI, UART, Socket).

Bus	Typical use cases
I2C	Sensors, EEPROM, PMBus, RTC, I/O expanders
SPI	Flash, ADC/DAC chips, display controllers
UART	Serial console, GPS, AT commands
Socket	TCP/IP instrument control (SCPI over LAN)

Send custom commands from this view as well as monitor passive traffic.

Power Supplies (PSUs)

ap-power-supplies.md

Dedicated controls for programmable power supplies.

Set voltage / current setpoint
Read back actual voltage and current
Enable / disable output
Configure over-current protection (OCP)
PMBus device programming

Charts

ap-charts.md

Live strip-chart and scope-style plotting of channel values over time.

Modules

ap-modules.md

Load, unload, configure, and clone software modules at runtime.

Ribbon → Tools → Modules

Module operations are also accessible via AccordionShell:

accordionshell module --module "MyModule" --file config.xml   # load
accordionshell module --module "MyModule" --rename "Clone"    # clone
accordionshell module --module "MyModule" --deactivate        # unload
