Help: Steps for creating an rtems device driver...

[Alex]

Hi,

Does anyone already created a rtems device driver?
I need to create a simple device driver to listen printer port, but I am lost in the steps i need to do...
Does someone know any doc with the steps to create a rtems device driver?
I already try to use the polled single port sample but i am lost, in registering, fire the driver, etc...

Thanks 

Nuno Costa
