obd-raw-data-parser/dist/src/obdUtils.js

A lightweight TypeScript library for parsing OBD-II raw data into human readable format. Based on the excellent work of obd-utils by Nishkalkashyap.

export function checkHex(n) {
    return /^[0-9A-Fa-f]{1,64}$/.test(n);
}
export function Hex2Bin(n) {
    if (!checkHex(n)) {
        return '';
    }
    const binary = parseInt(n, 16).toString(2);
    return zeroFill(binary.slice(-4), 4); // Take last 4 bits only
}
function zeroFill(number, width) {
    width -= number.length;
    if (width > 0) {
        return '0'.repeat(width) + number;
    }
    return number;
}
