As previous, I purchased an 8.4” LVDS display from ICOP, the kit manufacturer. In this article I cover getting the display working working. There were some issues for which I am got great support from ICOP in resolving.
Display: LCD-AU084-U-SET with touch / LCD-AU084-SET without touch
Target System: Vortex86DX- Spark Kit .. in enclosure. This has VDX-6326-256 single board computer
The out of the box system runs from a 5 volt plug-pack supply with little tolerance for input variation. As a location based game device, a major longer term objective has been mobility of the system. Therefore there is ultimately a need for battery a based power source. Typically such a system will need step-down regulation or some form switch stable voltage generation. A need arose during implementation for a 12 volt supply for the LCD display backlight.
The solution was to add a M3-ATX picoPSU unit internally to the box. The unit used generates 5V and 12V from an unregulated 7V to 30V input supply. The box was rewired so that the existing 5V input socket takes the nominally 12V input and is connected to the picoPSU device via the existing switch, (remembering to jumper pins 7 and 14 on the ATX plug of the unit).
I checked and double check everything and then started a boot and image download .. and it worked. Wala!
