My own environment was kernel 2.6.32.19 rtai 3.8.1 and emc 2.4.3. I can run realtime tasks, start emc and move the machine (sometimes). It survived my burn intests and the gentoo compiles. And I had no luck, there were no messages in the syslog files. The new ubuntu 10 emc envireonment works with kernel 2.6.32 and rtai 3.8.1, too Anyway, I tried some things and with the ubuntu version the system seems more stable than with my handmade one.

[Emc-users] Synchronized Component
Hello. I need to write a base thread component that does something based on the start of the servo thread (strobe AVR data lines). For example, I could have a base thread component that increments a counter. On the third count, do foobar, reset the counter and wait for the next servo thread start. I was thinking I could use the charge_pump component, but it toggles the output, so I would reset on every other servo period. I would also need to remember that charge_pump would need to be loaded. Is there a cleaner way to do this? Would having two functions, one in each thread, within the component add anything, compared to using charge_pump? Thanks. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA -- The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.

I looked at the source for the edge component. It has a variable called period that isn't declared in the top portion of the component. Does that mean that it is a global variable? If so, is there a convenient source for a list of global variables?

Hi Kirk Two possible solutions for you: first: Do you run ladder logic? if so, on wich thread? if it's the servo thread, you could use ladder counters and flip a pin. else you could write a comp module running in servo_thread wich counts and emits a pin. this pin you can use rising edge in the base thread to start your foobar rising edge means, you compare current status to last and only do foobar if last was 0 and now it is 1 second: you could write a comp module with two functions and a global counting var. one decrements the counter each time it is called, the other returns until count is zero and then it runs foobar and resets the counter then you addf this functions to base_tread and servo_thread. bye ulf -- The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.

[Emc-users] Parport Bulk Write
I am starting to think about how to put an eight bit word on a parallel port. My first guess is to load Parport, then write a component that shifts an unsigned variable a bit at a time to each parport pin, but I wonder if there is a cleaner way to write the whole (8bit) word to, lets say, pins 2-9? This will be used with a strobe component to latch data to an AVR port. -- Kirk Wallace http://www.wallacecompany.com/machine_shop/ http://www.wallacecompany.com/E45/index.html California, USA -- The Next 800 Companies to Lead America's Growth: New Video Whitepaper David G.

Re: [Emc-users] Suitable touchscreen?
Hi when i searched for touch screen i found local manufacturer of touch screen http://www.planartouch.com/ and it is best because there screen like glass - much more durable. It is capacitor type and more expensive because of that. aram I've had good luck with these screens... but I have never used these screens with Touchy.I put a 19 unit on a commercial waterjet and the system runs EMC2 with Axis for the front end. It worked out great.
