EMC2 CNC controller on mini2440

First release of miniEMC2 was released here
http://code.google.com/p/miniemc2/downloads/list. Welcome all who wants to
test it.

hey !

welcome to your project !  good idea 

but why not to start with a 6410 board directly ?

and please ... do the blog in English instead Russian ?..

best regards

Hi there,
main idea is to make more cheaper solution that PC. I guess the price of
mini2440 is well enough to satisfy this requirement.
There is nothing interesting in my blog. I temporary stopped an activity
there due to low interest from Russian guys. All info you need to build
miniEMC2 already provided on the Wiki page. If you need more details,
please send me an e-mail to address I've specified on the project page.

regards,
Sergey

Im impressed, very good job.
Hat off.

hey serg_io


you doing great !! from onwards  we can run emc2 on mini2440 ..!! it's
great news..


i also build RTlinux for x86 platform. and run emc2 in pc. 


I have one question. for that i need to compile kernel 2.6.35.9 with the
help of your miniemc2.patch that you mention on this linke that i mention
below

Dear Mr.
How could I access using emc on gpio?
Yours sincerely,

miniEMC2 uses GPIO access from FIQ interrupt handler, that is from kernel
space. If you don't need realtime access and some delays ( ~10 ms ) are
allowed, then you have two options. First, you can use sysfs to access
GPIO, see
http://code.google.com/p/miniemc2/source/browse/trunk/kernel/linux-2.6.3...
Second option can be mapping GPIO's address range into user space using
mmap of /dev/mem, see there:
http://code.google.com/p/miniemc2/source/browse/trunk/emc2-arm/src/hal/c...
, look for void *mapIoRegister(unsigned long addr, size_t length).

Sergey

Hallo Sergey
Thank you for the answer

Hello again
is it possible to use io in realtime?

Yours sincerely
