RE: Controlling pins



Yes, you can control the value on each pin individually.
The direction of the pins is changed in groups (e.g. all
8 data  pins on parallel port 0 must be in the same
direction).

If you want to control the pins from user space you can
do so by writing to the gpio driver that exists in the
2.4.19 kernel (refer to the thread about this a few days
ago).

If you want to control them from a driver you will find 
hints in the device driver example on www.axis.com.

There exists 2 parallel ports on the developer board (ETRAX 100LX). Is it possible to controll each of the 52 pins serparately? For example sending a signal over pin 8, 10, 20 and 48.
