Mini35 Development Package

The Mini35 is a development package comprising of a Mini2440 ARM9 development board and a 3.5" QVGA transposed touchscreen. This device is currently being used as a development tool in porting DexOS to the ARM microprocessor architecture, and will feature new subsystems that have a closer relationship with the hardware (I2C bus control for example).

Designed to be modular and portable, in the future the ARM9 version DexOS should work with most ARM9-based devices, with most hardware configurations being selected during the compile-phase of installation.

A circuit schematic for the Mini2440 development board is listed below in the references section1
