EL15 — ALIENTEK Electronic Load Controller (Rust)

Cross-platform controller for the ALIENTEK EL15 programmable DC electronic load. Single binary el15 runs as an iced GUI by default and as a CLI / SCPI server with --no-gui.

Workspace layout

Crate	Type	Purpose
el15-bt	lib	BLE protocol (port of DM40GUI)
el15-scpi	lib	SCPI/LXI raw-socket server emulating a RIGOL DL3000
el15-app	bin	Single binary el15 — iced GUI + --no-gui CLI + DFU + SCPI
scripts/scpi-test	bin	Smoke-tester for the SCPI server

Build

Requirements:

• Rust stable (1.75+)
• libusb-1.0 (macOS: brew install libusb; Linux: apt install libusb-1.0-0-dev; Windows: vcpkg install libusb:x64-windows-static-md)
• Linux GUI: see packaging/linux/README.txt

cargo build --release
./target/release/el15            # GUI
./target/release/el15 --help     # CLI help

CLI examples

el15 --list-usb                          # enumerate USB devices
el15 --no-gui --scan                     # scan for BLE EL15 devices
el15 --no-gui --port 5555                # connect to first EL15 + run SCPI server
el15 --no-gui --device <id>              # connect to specific BLE id
el15 --flash firmware.bin                # flash firmware via DFU
el15 --no-gui --log scpi.log -v          # verbose + log SCPI to file

Test the SCPI server

# Terminal 1
cargo run --release -p el15-app -- --no-gui --port 5555 -v

# Terminal 2
cargo run --release -p scpi-test -- --port 5555
