DragonFly Driver Hardware and Operating System
The DragonFly hardware is based around an ARM Cortex processor, and runs the Microsoft Windows CE 6.0
operating system. The hardware and operating system were specifically designed for embedded industrial
applications. There are no mechanical drives – all storage is flash based. The hardware does not require active
cooling, and is not damaged by power loss or cycling – even if the boot sequence is interrupted. If power is lost and
restored, the DragonFly will automatically reboot and recover without issue.
Internally, the DragonFly has a non-volatile flash drive which contains basic boot loader software. This boot loader
runs the main DragonFly software automatically on power up. The main DragonFly software and all relevant layout
and configuration files are stored on a removable micro SD card (refer to individual product wiring diagrams for
micro SD card location).
The TFT20 series DragonFly driving hardware can either be built around the RE1 or the RE2 engine. The RE1 offers
basic drawing options with no animation or video. The RE2 has hardware accelerated graphics allowing smooth
animation, alpha blending and live video playback.
There are no engine options with the TFT500, and hardware accelerated graphics is available in this unit by default.
