ADC
Analog-to-Digital Converter. Hardware that converts an analog voltage to a digital value. Used for reading sensor outputs, measuring voltages, etc.BLE
Bluetooth Low Energy. A wireless communication protocol for short-range, low-power devices.CLI
Command-Line Interface. Thelager tool you install via pip install lager-cli and run in your terminal.
DAC
Digital-to-Analog Converter. Hardware that outputs a precise analog voltage from a digital value. Used for generating reference voltages or test signals.DUT
Device Under Test. The embedded board or product you are testing with Lager.E-Load
Electronic Load. An instrument that draws a programmable amount of current from a power source, used to simulate real-world loads during testing.GDB
GNU Debugger. A widely-used debugger for embedded development. Lager starts a GDB server on the box that you can connect to remotely.GPIO
General-Purpose Input/Output. Digital pins that can be configured as inputs (reading HIGH/LOW) or outputs (driving HIGH/LOW).GPI
General-Purpose Input. A GPIO pin configured for reading digital state (HIGH or LOW).GPO
General-Purpose Output. A GPIO pin configured for driving digital state (HIGH or LOW).I2C
Inter-Integrated Circuit (pronounced “eye-squared-see”). A two-wire serial protocol (SDA + SCL) commonly used to communicate with sensors, EEPROMs, and other peripherals.Lager Box
A compact mini-computer (Cybergeek Mini PC) that sits in your lab, physically connected to your instruments and DUT. It runs the Lager container (Flask + SocketIO) which exposes HTTP and WebSocket APIs for hardware control.Net
A named logical connection to a physical instrument on a Lager Box — e.g.supply1 mapping to channel 1 of a Rigol DP832 power supply, or uart0 mapping to /dev/ttyUSB0 at 115200 baud. Nets decouple test code from specific hardware addresses, so the same script works as instruments move or change.
OCP
Over-Current Protection. A safety threshold on a power supply. If the output current exceeds this limit, the supply automatically shuts off. Clear withlager supply <NET> clear-ocp.
OVP
Over-Voltage Protection. A safety threshold on a power supply. If the output voltage exceeds this limit, the supply automatically shuts off. Clear withlager supply <NET> clear-ovp.
REPL
Read-Eval-Print Loop. An interactive prompt where you type commands and see results immediately. The Lager Terminal (lager terminal) is a REPL.
SCPI
Standard Commands for Programmable Instruments (pronounced “skippy”). A text-based protocol used to control bench instruments like oscilloscopes and power supplies.SOC
State of Charge. A percentage (0-100%) representing how charged a battery is. Used with battery simulator instruments.SPI
Serial Peripheral Interface. A four-wire serial protocol (SCLK, MOSI, MISO, CS) used for high-speed communication with peripherals like flash memory and ADCs.SWD
Serial Wire Debug. A two-pin debug interface (SWDIO + SWCLK) used by ARM Cortex-M microcontrollers. Used by debug probes like J-Link to flash firmware and debug code.Tailscale
A WireGuard-based mesh VPN that creates encrypted tunnels between your computer and your Lager Boxes. This is how you access boxes remotely.TUI
Text User Interface. An interactive terminal-based interface (as opposed to a graphical UI). Lager uses TUIs for net configuration (lager nets tui) and real-time power supply monitoring (lager supply <NET> tui).
