&lt;div&gt;This page was not written by Julian! These are just my notes from a beginning microcontroller programmer exploring the firmware.&lt;br /&gt;
&lt;br /&gt;
== Overview ==&lt;br /&gt;
&lt;br /&gt;
The drumsynth firmware (ie., not the interface board) is divided into a few logical parts: the hardware handling, the communications interfaces (MIDI via UART and USB, SD over SPI), the sound generation and the sequencer.&lt;br /&gt;
