Note that the first bit of the packed section is the key's actuated state if that is of interest

const value_hi = data.getUint8(i + 3);

const keyNamespace = (packed >> 2) & 0xf;
const value_lo = (packed >> 6) & 0x3;

const scancode = (keyNamespace << 8) | keycode;
const value = (value_hi << 2) | value_lo;

if (scancode === 0) break;
if (value === 0) continue;

active_keys.push({ scancode, value: value / 1023 });
