Controlling LEDs from a Java application
<p>I have jumped into the deep end in my new job and put myself forward to make a Java application that will send out a string of data to an LED display with the aim of further developing an Android app. I have studied Java in college and was pretty ok with it until now.</p>

<p>Here is the problem I have been given a PDF with the protocols to send data to this Multi-Line CPU via a wireless to serial adapter.  The data needs to be sent as the following</p>
