Install

Works with Claude Code, Codex, VS Code, Cursor, Windsurf, Claude Desktop. Read the repository before you give any tool access to your data.

npx agentmarket install connector/lukasz-juranek-usb-servo-controller

Asks which of your tools to add it to (Claude Code, Codex, Cursor, VS Code, Windsurf, Gemini CLI, Claude Desktop) and shows the change first. See https://agentmart.dev/cli.

Tools (16)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • board_status

    Rail current/voltage, faults, protection limits, and every channel's name, mode, travel limits, speed and current position (0 = off).

  • clear_faults

    Clear a latched overcurrent/undervoltage fault so channels can move again.

  • disable_servos

    Stop driving the given channels (numbers or names); the servos go limp.

  • go_to_pose

    Move to a saved pose (see list_poses) and wait until it arrives.

  • list_poses

    Poses and the sequence saved from the GUI (servogui.json).

  • measure_current

    Sample the servo-rail current continuously; returns peak, mean and min mA.

  • move_servos

    Move one or more servos and wait until they arrive. positions: {channel number or name: pulse width in us}, e.g. {"0": 1200}. duration_s: time for all to arrive together (0 = each channel's own speed). Positions are clamped to each channel's limits. Turns channels on if off.

  • play_sequence

    Play the GUI's saved sequence of poses (move and hold times as saved), repeated `loops` times. Stops early on a fault; capped at 120 s.

  • read_analog

    Read channel 0-7 as an analog input (0-4095 counts, 0-3.3 V).

  • release_port

    Close the serial port now (servos keep holding) so the GUI or flash.py can use the board. It reopens automatically on the next tool call.

  • run_script

    Start the stored script from the top.

  • script_status

    What script is stored on the board, and whether it is running.

  • set_protection

    Set the rail trip limits (0 disables either). Overcurrent is capped at 7500 mA: the board's continuous budget is ~5 A. Resets at power-up.

  • stop_all

    Panic stop: every channel off immediately.

  • stop_script

    Stop the stored script; servos keep their positions (stop_all to let go).

Show 1 more tools
  • upload_script

    Compile a servo script and store it in the board's flash, where the firmware runs it without a PC (autorun: also start at every power-up). One statement per line; channels by number or name; times in ms or '1.5s': label: jump/loop target move <ch> <us> [<time>] ramp there; does not wait: moves on different channels run together, a repeat move of the same channel waits for the previous one pose <name> [<time>] move every channel of a GUI pose sync wait until all moves arrive wait <time> off <…
