Now what?</h2> <p>The last chapter details the pains of getting the silicon to respond to us. What needs to happen next is a two way communication with meaning. Since we&rsquo;re working with a microcontroller, the first step is to establish a communication method that enables us to use the MCU as a bridge and talk to the target in such a way that we don&rsquo;t have to hard-code every single thing. Up til now, I&rsquo;ve set it to fire a command at the I2C bus on the push of a button and then report its&rsquo; findings over UART. The better way of doing this is to have the machine read the input from UART, parse the data into a command and argument form, then react accordingly.</p>
