2. Functional overview

IO-Warrior offers a simple access to the USB.

Many projects that formerly used the parallel port

or some other kind of direct I/O interface today

face the problem that getting simple things to work

on the USB is quite complex.

With a serial or parallel port you needed only a

simple circuit to control an external relay or read a

single switch.

With USB you need a microcontroller that handles

all the protocol work to do the same thing. Several

standard commands need to be supported to get a

device accepted as a USB device, let alone

implementing any real function.

IO-Warrior brings simplicity to the USB. The

protocol is encapsulated in the IO-Warrior Chip.

You only have to care about the I/O pins and have

to write only a few simple lines of code to access

them.

IO-Warrior also supports a range of industrial

standard interfaces to simplify interfacing to

certain chips or modules. These interfaces are

handled internally in IO-Warrior removing the

bandwith wasting controlling of individual pins.
