Since the rest of the document, and most other XMOS documents that had code, usually begin by posting all the code, then decompose it explaining what each line is doing, I thought this was worth pointing out.

Code: Select all

#include <xs1.h>

out port p = XS1_PORT_1A;

int main() {
  out port * movable pp = &p;
  buffered out port:32 * movable buffered_p;

  buffered_p = reconfigure_port(move(pp), buffered out port:32);
  *buffered_p <: 0xa0a0a0a0;
  pp = reconfigure_port(move(buffered_p), out port);

  return 0;
}
Thanks :)

Finally had the time to finish my xTIMEcomposer hello world tutorial:

xTIMEcomposer Hello World[/list]

Edited the first post to add it to the list.

I'd really really really appreciate input and some tips and tricks on using xTIMEcomposer as I'm planning on expanding the hello world project in my next post to cover basic concurrency and channel communication.

And one more installmenet: The Concurrent Blinkies

I wanted to have the threads declared to run explicitly on specific cores using

Code: Select all

on tile[0].core[x]:
But got "statement placed on a core must be call to combinable function" errors. Googling for that led me to this recent thread on the forums. The same search also lead me to the Programming real time multicore applications which describes cooperative multitasking on page 9. Is there any document, besides that, that talks about cooperative multitasking in more detail?

You cannot have the logical cores(threads) declared to run explicitly on specific cores as this does not make any difference in the execution as all the cores run independently. You can do it only while you are using two combinable tasks to specify which core the task has to run on. You can find more details about combinable task in the following document:
https://www.xmos.com/download/public/XM ... o-C(D).pdf

Usage of all these features are available as xSOFTip examples in the How To tab of the xTIMEcomposer tool.

Maybe I am an idiot, some have told me that. I am unable to find the doc with the mapping of the pins on the startKit board to ports on the MCU, so could you share the link with one of the great unwashed masses?

Thanks

Like I said sometimes I can be an idiot, the hardware manual is the obvious place to look.

Thanks that solves this problem,

wade
