• build pkg npm run build

publish to npm

• npm login
• npm whoami
• npm publish

Cách sử dụng package

• install package npm i phenet-obd2-pids

Khởi tạo command

• import

  import { ServiceManager } from 'phenet-obd2-pids';
  import { ServicesName, PIDsName } from 'phenet-obd2-pids';

• khởi tạo object service

  var service = new ServiceManager();

• khai báo command template:

  let cmd = JSON.parse('{"time": "null", "data": ""}');

• append các pids cần request:

  service.appendCommandService(ServicesName.MODE_3_REQ_DTCS, cmd);
  service.appendCommandPID(PIDsName.Engine_speed, cmd);
  service.appendCommandPID(PIDsName.Throttle_position, cmd);
  service.appendCommandPID(PIDsName.VIN, cmd);
  service.appendCommandService(ServicesName.MODE_4_CLEAR_DTCS, cmd);
  console.log(cmd);

• kết quả print log:

  Object { time: "13:33:7:356", data: "/2015:2:3:0:0:0:0:0:0/2015:2:1:12:0:0:0:0:0/2015:2:1:17:0:0:0:0:0/2015:2:9:2:0:0:0:0:0/2015:2:4:0:0:0:0:0:0" }

Decode command nhận được từ ESP

• decode data nhận từ ESP (đã decrypt)

  // fake command
  let recv_cmd = JSON.parse(
  '{ "time": "13:28:58:730", "data": "2024:3:65:12:18:52:0:0:0;/2024:3:65:13:18:0:0:0:0;/2024:16:20:73:2:1:51:70:65;2024:33:68:80:52:70:74:50:66;2024:34:77:49:49:51:57:49:51;/2024:16:20:67:2:1:51:70:65;2024:33:68:80:52:70:74:50:66;2024:34:77:49:49:51:57:49:51;/"}'
  )
  // decode command
  let results = service.decode(recv_cmd);
  // print result
  console.log(results.data.split('/').filter(Boolean));

• kết quả print log

  Array(4) [ "1165", "18", "3FADP4FJ2BM113913", "P0133;C0641;C0450;P3446;C01032;C02413;P3131;P3339;P3133;" ]

code example

import { ServiceManager } from 'phenet-obd2-pids';
import { ServicesName, PIDsName } from 'phenet-obd2-pids';

var service = new ServiceManager();

// ### Khởi tạo command (encode) ###
/* test Service */
let cmd = JSON.parse('{"time": "null", "data": ""}');

service.appendCommandService(ServicesName.MODE_3_REQ_DTCS, cmd);
service.appendCommandPID(PIDsName.Engine_speed, cmd);
service.appendCommandPID(PIDsName.Throttle_position, cmd);
service.appendCommandPID(PIDsName.VIN, cmd);
service.appendCommandService(ServicesName.MODE_4_CLEAR_DTCS, cmd);
console.log(cmd);

// ### Decode ###
// fake command
let recv_cmd = JSON.parse(
  '{ "time": "13:28:58:730", "data": "2024:3:65:12:18:52:0:0:0/2024:3:65:13:18:0:0:0:0/2024:16:20:73:2:1:51:70:65;2024:33:68:80:52:70:74:50:66;2024:34:77:49:49:51:57:49:51/2024:16:20:67:2:1:51:70:65;2024:33:68:80:52:70:74:50:66;2024:34:77:49:49:51:57:49:51/"}'
)
// decode command
let results = service.decode(recv_cmd);
// print result
console.log(results.data.split('/').filter(Boolean));
