Modified the code to handle 0 to 25,900 feet, and a 16 bit conversion lookup table. Now you can select your conversion oversampling rate for Darrel's code, and your result gets shifted to match the 16 bit lookup table for altitude conversion. Works for 10 to 16 bit oversampling rates. My favorite is the 15 bit for accuracy and speed, but it is selectable.
