... start the table with the entry for '0'. Starting at '0' means you skip the ASCII codes for things like space, plus, and minus - which may or may not matter in this particular application... Use the now "extra" bit to indicate when an entry in the table does not encode to a valid display pattern. You will, of course, have to make your own decision on what to do about characters that cannot be displayed on 7 segments... |
