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 that you test 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
Any x86-64 machine that runs Ubuntu 22.04 or newer, such as a compact mini PC. It sits on your bench, wired to your instruments and DUT. It runs the Lager container (Flask and SocketIO), which exposes HTTP and WebSocket APIs for hardware control. See Setting Up a Lager Box.Net
A named logical connection to a physical instrument on a Lager Box. For example,supply1 maps to channel 1 of a Rigol DP832 power supply. uart0 maps to /dev/ttyUSB0 at 115200 baud. A net separates test code from a specific hardware address. The same script keeps working when an instrument moves or changes.
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).
