<p class="intro_text" >
Tufts CEEO has developed a custom firmware based on MicroPython for SPIKE Prime Hub and SPIKE Essential Hub that enables UART and I<sup>2</sup>C communication (as well as individual digital pin control) via the SPIKE ports. This allows SPIKE Hubs to communicate with a wide variety of external devices (breadboards, microprocessors, and other third-party electronic hardware). Note: this version of the firmware does NOT support any of the other LEGO functionality (provided by the LEGO Hub OS, like default program, program slots, LEGO Python API, etc).

<div class="list-div">
<h2><strong>Installation Instructions (via Hub's bootloader mode)</strong></h2>
<p class="intro_text" >The LEGO Hub supports the MicroPython firmware. The Tufts CEEO SPIKE Firmware (MicroPython) is built on top of the default MicroPython implementation. First, you need to install the <a href="https://micropython.org">MicroPython firmware</a>. Then you need to add the Tufts CEEO SPIKE Firmware (MicroPython) features on top. This will enable UART and I<sup>2</sup>C communication (as well as individual digital pin control) via the SPIKE ports.</p>

<ul role=" list" class="list-4">
<li class="list-item-20-indent">Place the Hub in bootloader mode:
<ul role=" list">
<li>Turn off the Hub.</li>
<li>Disconnect the USB cable.<br></li>
<li>Press and hold the Bluetooth button (SPIKE Prime) or power button (SPIKE Essential).</li>
<li>Connect the USB cable (to both the Hub and your computer).</li>
<li>Wait for the Bluetooth light to start blinking pink-green-blue-off (SPIKE Prime) or wait for the status light to start blinking light purple (SPIKE Essential).</li>
<li>Release the button; Hub is now in bootloader mode.</li>
