 Helms Display
 =============
 
+# Background
+
+So, I'll try to make a somewhat decent Openplotter setup on a Raspberry PI 3; not the + version, just 3. It's fairly powerful whilst not consuming too much power. I have various peripherals lying around, such as a cheap NEO-M6 GPS chip, an MPU-9250 compass and more, and rtlsdr -- I even have an HDMI monitor that I'm gonna try and fit to 12V, but I'd like a small display for the helmsman. Thus this project.
+
+The idea is to find a cheap, small, GPIO connected monitor and have it display useful data; not necessarily full-blown maps and pictures, but navigational help. I found an ili9488 display on Ebay, and this project is about making this small display show stuff from Openplotter (basically SignalK).
