title: How can you add your own Forth program and execute in the Mecrisp-Ice 0.8 -enhanced fork of Swapforth by James Bowman?
body: <p>I want to write LED blinking code in Forth. I have knowledge of the I/O peripherals address mapping of ICEstick or the Verilog code written for <a href="https://github.com/zuloloxi/mecrisp-ice" rel="nofollow noreferrer">Mecrisp-Ice 0.8</a>. When I open nucleus.fs - the heart of the J1 CPU, I find &quot;: main&quot; and below are the words &quot;2emit&quot; which are used to send characters Mecrisp-Ice 0.8 serially.</p>
  <p>Should I write the LED blinking program in this section?</p>
