What is GEVINO-Motor AGENTS.md?

Programming instructions for the GEVINO Motor, an Arduino-compatible industrial controller for stepper and brushed-DC motors. It covers the board's inputs, outputs, communications, storage, and motor driver, plus rules for writing its firmware.

Use it to write or review Arduino/C++ firmware for GEVINO Motor, including motor control, sensors, outputs, RS485 communication, and non-blocking control logic.

It gives coding agents the hardware details and safety rules needed to generate code that matches the controller instead of treating it like a generic Arduino board.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

GEVINO-Motor AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

AGENTS.md — Programming guide for the GEVINO Motor

This file is written for LLMs and AI coding agents (Claude Code, Cursor, Copilot, etc.) that write firmware for the GEVINO Motor PLC. It is also useful to human developers. If you are generating Arduino/C++ code for this board, follow these rules.

What the board is

GEVINO Motor is an Arduino Zero compatible motor-control PLC based on the Microchip SAMD21 (32-bit ARM Cortex-M0+, 48 MHz, 256 KB flash, 32 KB RAM) and a Toshiba TB67S128FTG driver (one stepper or two brushed-DC motors, constant current 50 V / 5 A, 10 A peak, microstepping to 1/128). It has 5 PNP inputs, 4 protected PNP outputs, 3 analog inputs (+ 2 motor-current channels), an RS485 bus, a micro-SD slot and optional Ethernet / Wi-Fi modules. Program it with the Arduino IDE using the Arduino SAMD core (board Arduino Zero, Native USB Port); it also works with Cursor and OpenPLC.

The complete pin map and specifications are in README.md and in the single library header src/gevino_motor.h.

Golden rules

Write non-blocking, state-based code. Prefer switch/case state machines. Never block the loop() with delay() in production logic (short delayMicroseconds() between microsteps is OK).
Include a sine table first, then the library:
```
#include "Sinewave128.h"   // 1,2,4,8,16,32,64,128,256,512,1024 microsteps
#include "gevino_motor.h"
```
The library references dataword_rom / SinwaveTableSize, which the Sinewave*.h table defines.
Include gevino_motor.h in exactly ONE translation unit (your main .ino): it defines global objects (ISEq, Param, analogResult, …) and functions.
Do not initialise the I/O yourself. gevino_motor_setup() configures every pin, drive strength, LEDs, RS485, the driver pins and resets the Ethernet module. Call it once in setup().
Use the macros (In1…In5, setOut1…setOut4, resOut1…resOut4, setLed, set_Rs485_TxEn, setLATCH/resLATCH, setBANK_EN/resBANK_EN, setSTANDBY/resSTANDBY).

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
