Serial

A serial device library written in TypeScript for Deno without third party libraries.

import { Serial, baudrate } from "./mod.ts";

const serial = new Serial();

const availablePorts = serial.getAvailablePorts()

console.log('serial properties (available ports):', availablePorts);

console.log('serial properties (isOpen):', serial.isOpen);

console.log('serial.open():', serial.open(availablePorts[1].name, baudrate.B9600));

const textToSend = 'Hello World!'
const dataToSend = new TextEncoder().encode(textToSend);

console.log('serial.write():', serial.write(dataToSend, dataToSend.length, 10, 10));

console.log('writing:', textToSend);

const dataToRead = new Uint8Array(20);

console.log('serial.read()', serial.read(dataToRead, dataToRead.length, 10, 10));

console.log('reading:', new TextDecoder().decode(dataToRead));

console.log('serial.close()', serial.close());

Arduino:

char incomingBytes[10];

int charsRead = 0;

void setup() {
  Serial.begin(9600);
  while (!Serial) {
    ;
  }
}

void loop() {
  int available = Serial.available();
  if (available > 0) {
    charsRead = Serial.readBytes(incomingBytes, available);

    Serial.print(incomingBytes);
  }
}
