I don't think realtime is necessary for my needs but I wouldn't object to it either if I could get the same type of graphics and display. I am getting past the i/o pin limitation on RPI by using multiplexers to sequence through the sensors. At this point I think I'll stick with RPI and let you develop on the Beaglebone, although your piqued my interest now and will probably take a look at it.</div><div id="yui_3_16_0_1_1527194451977_36721" dir="ltr"><br></div><div id="yui_3_16_0_1_1527194451977_36721" dir="ltr">Jon </div><div class="qtdSeparateBR" id="yui_3_16_0_1_1527194451977_36725"><br><br></div><div class="yahoo_quoted" id="yui_3_16_0_1_1527194451977_36846" style="display: block;"> <div style="font-family: times new roman, new york, times, serif; font-size: 16px;" id="yui_3_16_0_1_1527194451977_36845"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;" id="yui_3_16_0_1_1527194451977_36844"> <div dir="ltr" id="yui_3_16_0_1_1527194451977_36843"> <font size="2" face="Arial" id="yui_3_16_0_1_1527194451977_36842"> <hr size="1"> <b><span style="font-weight:bold;">From:</span></b> irox via Personal_Submersibles <personal_submersibles@psubs.org><br> <b><span style="font-weight: bold;">To:</span></b> Personal Submersibles General Discussion <personal_submersibles@psubs.org>; Personal Submersibles General Discussion <personal_submersibles@psubs.org> <br> <b><span style="font-weight: bold;">Sent:</span></b> Thursday, May 24, 2018 12:33 PM<br> <b><span style="font-weight: bold;">Subject:</span></b> Re: [PSUBS-MAILIST] DSV Aquatic update<br> </font> </div> <div class="y_msg_container" id="yui_3_16_0_1_1527194451977_36850"><br><div id="yiv4324265166"><style type="text/css"><ZZZ!--#yiv4324265166 DIV {margin:0px;}--></style><div id="yui_3_16_0_1_1527194451977_36849"><div style="font-size:13px;color:rgb(0, 0, 0);font-family:arial, sans-serif;" id="yui_3_16_0_1_1527194451977_36848">Hi Jon,<div><br></div><div id="yui_3_16_0_1_1527194451977_36847">the UI looks awesome.

Due to limited screen "real estate" it was important to layer information based upon importance. Those things that I consider essential information appears on the initial display...depth, duration, heading, warnings, and access to engines. You'll note that depth, duration, and warnings are always displayed regardless of what other information is being displayed. </span>Graphics is a matter of personal preference.

The wifi capability with VNC means I can even access and control the display with my phone. On the surface at least, a support team could use their own phones to log into the SCM and monitor my submarine systems.
