Re: [OT] RTOS recommendations?

Hi-

Since this is an open question, I would suggest you look into the Arduino 
platform.  It consists of an IDE based on Processing, C, and C++, which compile 
to Arduino boards.  There are many Arduino compatible boards (ATMega168, 328, 
644, etc), and many more 'shields', which are i/o specific pluggable boards 
whihc have such things as Servo, Stepper motor, Ethernet, RF, RFID, etc 
implemented.  

These would be a good basis for robotics and so on.  The IDE has a well 
developed set of libraries.  

Start at http://www.arduino.cc and explore.  

There are the beginnings of similar offerings based on PIC, ARM, etc 
microprocessors.

Hmmm. I'll try that seeing as 7.50 appears to be broken now

I used to do the same :)

definitely agreed with the recommendations. And as for contrast, I used 
to use a I2C DAC , with an op-amp to give some more "strength" to the 
DAC's output and if needed to make it negative.

Re: [PIC] Pic simulator


I use MPLAB and their C compilers, but I've also been using BoostC and the 
http://www.sourceboost.com/ SourceBoost IDE  alot. 

You can get the IDE and a limited noncommercial version of BoostC for free.
The freeIDE contains some simulation plugins, but what's really cool is the 
http://www.sourceboost.com/Products/IdePlugins/Overview.html extra plugins 
you can get for $20.

There are also a few 3rd-party plugins from some users, you can find them on
the SourceBoost forum.

Re: [OT] RTOS recommendations?

David,

I'm surprised that you'd say this.  AFAIK about the Arduino, it  
doesn't do proper video, nor a standard keyboard/mouse input.  Of  
course I can code these, but would prefer to avoid it if possible.

My other major concern is its ability to deliver stepper pulses at  
over 1MHz to each of a few steppers simultaneously at different  
speeds, cause IIRC it runs on a 16Mhz or 20Mhz microcontroller.   
Correct me if I'm wrong here.

Cheers,
-Neil.

Re: [OT] RTOS recommendations?

I am quite aware of EMC, cause a few years ago I evaluated it along  
with Mach3 for running a CNC mill.  Mach3 was up and running very  
quickly, so I bought the license and stuck with that.  Which is so  
unlike me (Linux rules! :).

But I know how capable EMC is.  What I was not aware of is EMC's  
ability to be controlled by Python.  I will investigate further now,  
but you're saying that I can write a Python app that will send all the  
parameters to EMC for motor movement, while my app simultaneously  
provides information on the screen to the user?  If so, this would be  
excellent.

Cheers,
-Neil.

Re: [OT] RTOS recommendations?

Oh, sorry -- I guess I misread your application.  ! MHz to steppers sounds
awfully fast.

Re: [OT] RTOS recommendations?

PicDude --

I would agree with the previous poster that you split your applications up --
the video, keybosrd, audio etc would be a PC/laptop.  The Arduino was meant to
do the low level timing for servos and stepper motors - if they can keep up ?!.  

Otherwise, it gives you a nice IDE with usb real-time connection to the
hardware, access to Processing for PC programming. http://processing.org/

Re: [AD] Bluetooth 'industrial' serial module

I didn't see the FCC mark in the documents, but it claims "Bluetooth Qualified product". I can check with the supplier.
