Binary Packing, Bits & Hex

Available on: Flexs Q5C Flexs Q5 Pro Flexs Q5M

Round-trips data through the bin conversion functions: packing a bit array to bytes with "RBITS", converting between binary and hex text with bin.toHex/bin.fromHex, and packing/unpacking word-swapped 32-bit floats ("F32" + "BADC").

print("==== Convert an array of 16 bits to a binary string of two bytes ====");
{
  let bitArray = [ 1,0,0,0,0,0,0,0,    0,1,1,1,1,1,1,1 ]; // true or false could be used
  let bytes = bin.fromArray(bitArray,"RBITS");
  let hex = bin.toHex(bytes);

  print("raw bit array:", string(bitArray) );
  print("packed to bytes: ", hex); // 01fe
}
print("");

print("==== Convert two bytes from a hex string into an array of bits ====");
{
  let bytes = bin.fromHex("01fe");
  let bitArray = bin.toArray(bytes,"RBITS");

  print("raw hex: ", bin.toHex(bytes));
  print("converted to array: ", string(bitArray));
}
