A chronicle of BoatBus: my EE hobby
To an extent, this is to show what can be done at the hobby level, with a bt of time and ingenuity. Right now it's called BoatBus II for lack of a better name. It uses processors, LCD displays controlled by FPGA, and lots of analog sensors. It uses a simple RS-485 network to allow multiple sensors and displays can talk to each other. I'm making it wide-open so others can use what I've developed. Schematics, PC layouts, FPGA's and source code are all posted here. Need FPGA code for an LCD controller? It's here. Need a simple graphics library? RS485 network protocol? All here. Enjoy!
few years I've
been working on this networked display and data acquisition
It's a work in progress, and I plan to use it on both my boat
home to display and control lots of stuff. I did
the first generation of a similar system about 12 years ago
surplus LCD panel, a 68hc11 micro, and a bunch of code and
hardware, including an LCD controller in an FPGA.
It was a single box system designed to provide my boat with a
marine-type data: wind speed and direction, boat speed and
also provided rudimentary navigation by maintaining a
I used it for two years aboard my old boat. When I moved to a
boat, I never installed it. It's size was inconvenient and not
the hassle to wire it all up.
Since then, LCDs and FPGAs
have gotten a bit better, procesors are faster and more
C tools have gotten a bit better. The updated, BoatBus II
