@emdzej/ediabasx-protocol-uds

UDS (ISO 14229) service identifiers, negative-response codes, and ISO-TP framing helpers (single / first / consecutive / flow-control frames). Part of EdiabasX.

Install

pnpm add @emdzej/ediabasx-protocol-uds

Usage

ISO-TP segmentation

import { segmentIsoTpPayload } from "@emdzej/ediabasx-protocol-uds";

// Splits a UDS payload into 8-byte CAN frames per ISO-15765-2.
const frames = segmentIsoTpPayload(
  new Uint8Array([0x22, 0xf1, 0x90, /* …VIN read… */]),
);

for (const frame of frames) {
  await canTx.send(frame); // your CAN driver
}

The interface-serial package's K+DCAN ISO-TP path uses this internally for D-CAN ECUs.

Service IDs and NRCs

import { IsoTpFrameTypes } from "@emdzej/ediabasx-protocol-uds";

if (frameType === IsoTpFrameTypes.FlowControl) {
  // …
}
