EMC on friendlyARM mini2440

hi all, i am new to emc community !
i have built a cnc mill using emc2 from my computer. now i want to run my mill by FriendlyARM mini2440.
How can i convert or change parallel port settings to GPIO of ARM board ?
Any Suggestions ?

Thanks in Advance....................

Thanks for your quick reply !
i have checked the file "hal_parport.c" in source directory.......
it has three operations : parport.0.read , parport.0.write etc

if i want to create a gpio hal driver then, specifically which driver files are required to build or modify ?
because i have no idea about parallel port HAL files.....

Waiting for reply ................

Thanks again.........

yes, i have compiled the kernel and emc2 for arm-Linux-gcc432 compiler........

the kernel works perfectly,
but when i tried to compile emc2 source it gives error about parport as no such hardware.........

now what have to do ?
create the gpio drivers first or try to change parport drivers ?

if i change the base address of parport to base address of gpio then it will work or not ? ........

As an experiment, just delete all references to the parport in the Makefile then compile.

Does the RTAI latency test run? What numbers do you get?

Yes!
I also want to recocnize this!

I am very interested in your work with the Mini2440, I have just started playing with my friendly ARM board, If possible I would very much like to share and contribute to this project, I am prototyping a CNC system and would like to use a low cost embedded solution like this VS a stand alone PC, the boards I use are based on the Toshiba TB6560AHQ chips, if there is any chance of sharing your code with me I would very much like to contribute to make this work...

I have programmed in various languages including C++. C#, VB.net, and VB Pro for nearly 25 years..

I have extensive experience with EMC running on a PC and a Sherline CNC mill setup, I am now moving into development of my own system to offer to others and I am exploring embedded systems as an option for a particular machine...

You can see www.cnczone.ru/forums/index.php?showtopic=1727 with example of using Friendly ARM

I've no experience of that but I have used the mini2440 which they also have on that site:

Admittedly that's $88 but that includes the LCD screen. The mini2440/micro2440 is a brilliant way to get into ARM9 based Linux

development!
