This program is free software you can redistribute it and/or modify it under the same terms as Perl itself. In particular this is the first release of Windows and a fully working auto driver. Lots of imporvements to documentation, auto load modules etc. Stable - I beleive it is stable, but this is only on my own testing and machines. Windows work only in early pre-alpha testing.
#Parallel port drivers
Worked for Linux ROOT and Linux parport drivers only.

For full history see Changes in the package. History here covers central Device::ParallelPort and not the specific drivers, see them individually. Refer to TODO list with packages and code. Pin No (DB25) - Signal name - Direction - Register - bit - Invertedġ - 7 nSelect-Printer - Out - Control-3 - Yes Note also the Inverted flag.Ī number of real projects have been produced using Device::ParallelPort. DISCUSSIONS Hardwareįollowing is the standard hardware table, so that you can find the correct pins and information. Don't, whatever you do, use this for drivers that need fast access.

It is designed to give you simple access to a very old device, the parallel chip. Therefore for this reason these three bytes are controlled by the above methods. The first is data, second is control and third is status. The normal parallel port is broken up into three bytes. get_data ( ) set_data ( VALUE ) get_control ( ) set_control ( VALUE ) get_status ( ) set_status ( VALUE ) NOTE - VALUE must be a single charachter - NOT an integer. This is actually a ridiculous limitation as almost all parallel chips allow all three bytes to be inputs or outputs, however drivers such as linux parallel port does not allow you to write to the status byte. For example the stock standard parallel controller does not allow you to write to the status entry. Don't forget that some devices don't allow you to write to some locations. set_byte ( BYTENUMBER, VALUE )īytes again. This is the method I use above all others, in particular to turn on and off rellays. As per get_bit most drivers only have access to 3 bytes (0 - 2). get_byte ( BYTENUMBER )īytes are some times more convenient to deal with, certainly they are in most drivers and therefore most Devices. The driver will most likely croak if you ask for a bit out of range. Normally you can consider a printer driver having 3 bytes (that is 24 bits would you believe). You can get any bit that is supported by this particular driver. L - SerialFlash of bits - useful for many driver chips METHODS new CONSTRUCTOR new ( DRIVER )Ĭreates a Device::ParallelPort.

L - Windows 32 DLL access driver DEVICE MODULES L - An example that can talk to a printer L - Direct hardware access to a base address. NOTE - You MUST load one of the drivers for your operating system before this module will correctly work - they are in separate CPAN Modules. NOTE - This actual module is a factory class only - it is used to automatically return the correct class and has not other intelligence / purpose. Modules are available for linux (both directly and via parport), win32 and a simple script version. This module provides an API to all parallel ports, by providing the ability to write any number of drivers. $port->set_byte(0, chr(255)) DESCRIPTIONĪ parallel port driver module.
