This application note describes a method for developing block-oriented I/O device drivers

for applications that use the DSP/BIOS real-time kernel and includes examples that run

with Code Composer Studio v2.1 on the Texas Instruments TMS320C5402 and

TMS320C6711 DSP Starter Kits (DSKs). The device driver model presented here has

now been superceded with an updated version that supports not only block oriented

devices, but also devices such as UARTs, PCI and USB buses and Multimedia cards.

Documentation on the updated driver model as well as example drivers and source code

can be found in the Device Driver Developer s Kit product now available for download

from the TI Developer s Village.-This application note describes a method f or developing block-oriented I/O device drive rs for applications that use the DSP/BIOS real- time kernel and includes examples that run with Code Composer Studio v2.1 on the Texas Instrume nts TMS320C5402 and TMS320C6711 DSP Starter Ki ts (DSKs).
