Jeremy, > Doug you kick ass. My friend has a t-shirt that says "equal opportunity ass kicker" <g> > I probably am not going to use a SBC I am probably gonna > go with the VIA EPIA board.... so what shoulf I be looking for. The VIA EPIA Manual is here: http://www.viavpsd.com/product/3/4/EPIA-M_Manual_v1.0.pdf At first I thought this board didn't support flat panels, but the manual says "1 connector for LVDS module (optional). This board doesn't appear to have flat panel connector like most embedded boards. It looks like it's assumed that people will connect to analog VGA or TV (NTSC) devices. If you want really crisp and nice flat panel output, I suggest that you find this "LVDS module" and mate that with the EPIA ... the module is an LVDS transmitter. See this paper on LVDS ... http://www.9xmedia.com/Pages/Technology%20-%20LVDS.html With the appropriate LVDS module, you can connect EPIA to flat panels that support LVDS ... however there still might be an issue of pinout/pin mapping (I'm not sure because I still haven't tried LVDS but will be doing that soon). With EPIA you only have three options: analog VGA, TV (NTSC) output, and LVDS to flat panel. Most of the HMDs including Tekger M1 and MicroOptical SV-3 accept analog VGA inputs, so you can use either of those with the analog VGA port. The M1 can also be driven by a smaller driver using the TV out signal (RS170 module). For flat panel support, you either need an LVDS module for that board or an LCD controller board that accepts analog VGA and converts to digital. Earth LCD has some of those (see below) but they are not small and they tend to use a lot of power. http://www.earthlcd.com/controllers.htm > TFT LCD.. Touch screen overlay that will work as a > mouse, and what kind of connection? VGA? LCDs that already have integrated touch screens are very expensive (except for small PDA screens but that is a different world, they are really designed to connect to processors like SA-1110 etc and support only QVGA, which usually is NOT supported on x86 boards). Therefore, it's more economical to find a nice flat panel without touch screen and add an overlay (they are available in different sizes). For connection (signal), I think that LVDS is the best way to go. Keep in mind that "VGA" can mean different things .... the "VGA port" (15-pin DSUB connector) is ANALOG ... it will NOT drive an LCD (which is DIGITAL) without extra hardware. This is why most SBCs have BOTH analog VGA ports and flat panel connectors (digital). It's kind of sad IMO but mating an LCD with SBC is not all that easy unless you go with big/bulky/power hungry and expensive parts. I'm still eyeing the Toshiba 4 inch VGA display ... which does 200 pixels per inch ... I want to try that ... http://wearables.blu.org/wear-hard-02/20027037.html Hope this helps ... -- Doug -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org Please, *PLEASE* don't subscribe through a forward/expander/false domain
