<div dir="ltr"><div>I see depth on your navigation HMI but not altitude. Are you planning on adding this sensor? Having run my boat for several years, I find that all data is not equally important. What I find I check a lot are SOF of air tanks, SOC of batteries, depth, altitude, O2 and CO2 levels, and compass heading. Other parameters I check less frequently. Also you use an aircraft roll, pitch and compass heading style indictor which looks very nice. Having said that, my experience is that K boats have a large spread between CB and CG. As such my guess is that your indicator will not show much variation in pitch or roll under normal operating conditions but of course your heading will be active. </div><div><br></div><div>Keep updates coming. I enjoyed video. Would be nice to have voice over as you walk through buttons and screens on HMI.</div><div><br></div><div>Best Regards</div><div><br></div><div>Cliff</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, May 23, 2018 at 7:33 PM, Jon Wallace via Personal_Submersibles <span dir="ltr"><<a href="mailto:personal_submersibles@psubs.org" target="_blank">personal_submersibles@psubs.org</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div><div style="color:rgb(0,0,0);font-family:times new roman,new york,times,serif;font-size:16px;background-color:rgb(255,255,255)"><div id="m_7306179311736341616yui_3_16_0_1_1527120823372_3083"><span></span></div><div id="m_7306179311736341616yui_3_16_0_1_1527120823372_3083" dir="ltr"><span id="m_7306179311736341616yui_3_16_0_1_1527120823372_3103">I have finalized the PCB layout for the SCM. Although not really necessary, layering various "breakout boards" onto PCB foundations that use electrical traces to connect various parts will definitely cut down on the mish-mash of wiring that would otherwise be required. I have settled on a configuration providing 16 each of analog, serial, and I2C sensors. This is way more than I ever anticipate needing however it does offer plenty of room for expansion and doesn't cost much more than limiting to 4 or 8 sensors...so why not go for it.</span></div><div id="m_7306179311736341616yui_3_16_0_1_1527120823372_3083" dir="ltr"><span><br></span></div><div id="m_7306179311736341616yui_3_16_0_1_1527120823372_3083" dir="ltr"><span id="m_7306179311736341616yui_3_16_0_1_1527120823372_3557">I am using ExpressPCB for the PCB design work.
