TI-84 Plus CE Hex Codes
=======================

Overview
~~~~~~~~
This page contains a list of useful hex codes to be used with ExecHex. To use them, follow the ExecHex documentation with the preferred hex string. Some of these may perform similar utilities to pre-existing Celtic functions. A good number of these were taken/adapted from the TI-BASIC Developer `84 Plus CE Hexcodes page <http://tibasicdev.wikidot.com/84ce:hexcodes>`__.

    This is harmless, but it stops displaying that blinking cursor :D Just press [2nd][MODE] to put it back to normal. What, jokes are allowed, right?

    Turns on the cursor::

.. function:: Draw TI Logo
    
    This is a strange function that draws the TI Logo. (Yes, there is a built in ASM call to do that) While there is no real reason you would probably want to do this, it's still interesting::
