Question

I want to convert 24 byte BCD to ASCII.Im trying to write some code for this conversion but Im not sure how to do the math for it. Suggestions?

This is my input data,
cd00320000a4002a00001042
Tag (24 Byte BCD)

Answer 1

This would work:

StringBuilder sb = new StringBuilder(bcdDigits.length * 2);
for (byte b : bcdDigits) {
  sb.append(String.format("%02x", b));
}
System.out.println(sb.toString());

Packed BCD->String conversion is essentially the same as conversion to hexadecimal string, only without a-f characters.
