EMC2 running on Raspberry Pi?

A kickstarter if/when things come together would be nice, although I know that's far from a simple ordeal.

It is possible to run LinuxCNC on the Rasberry - in principle. It compiles, and runs on a Xenomai kernel.

that said, be advised that at least with Axis, the Pi runs out of CPU cycles badly - you might want to adjust your expectations downwards a bit.

Here's the youtube link to an actual test using the miniemc2 frontend:



Cheers!

FWIW, here is the screen grab of RPi running Axis over remote X:



Note that RPi is overclocked to 800 MHz.

The sshd load drops considerably if the preview is disabled, it goes down below 10%.

Hi Kinsa,

congratulations - great job!

Assuming this is based on miniemc2 - did you replicate Sergey's fast IRQ driver? I'd be rather curious about that because it could be a reasonable alternative for ARM boards which dont have something like the onboard PRU of the Beaglebone processor.

Will you publish the changes to miniemc2?

regards

Michael

Thanks.

This is the rtos-integration-preview3 branch git code; this is all your work . The only addition I made is the hal spi driver for the PIC32 board. I will post the code once I am done with the cleanups.

Regarding miniemc2, I have only taken the web-interface and made it run on the latest code. It's a bit of a kludge, the author made some changes to shcom.cc, and I'm not sure if it is the "right" way of doing it.

Cheers!
