Re: FOSDEM 2011

I would like to correct that I will not present the project myself. Christophe Scholliers from the VUB University in Brussels will do that.

Re: "Dynamic select" for interpreter

I'm trying to make something like this (very similar to the scheme "cond"), but providing the functionality of an XC "select": (select ((pinnotequal pin 2) ....) ((timeafter x) ....) (else .....) ) Thanks for the help already, as I'm not really familiar with the XCore instruction...

"Dynamic select" for interpreter

As some of you might already know, I'm working on a Scheme interpreter for XMOS devices. One of the things I still need to implement is the "select" statement. The problem there is that the exact select statement (number of cases, etc..) is not known at compile time. So I need to make some...

Re: 31 bit timer

That will AFAIK only work as long as you don't want to do something like this: timer t; t when timerafter ( time ) :> void ; The problem is that the value of time will always be in the range of 0x0000.0000 & 0x8FFF.FFFF (31 bit). However, half of the time the above code will not work properly be...

31 bit timer

As you might know I'm working on running interpreted languages on XMOS devices. I dropped the previous interpreter (which can be found in projects) for a much better (bytecode based) one. Now it comes with a problem which is that integers are 31 bit (one bit is used as a flag). For most applications...

Re: "on stdcore" malfunction?

OK :roll: , now I feel incredibly stupid :oops:

I'm like already working with the board for months and I can only vaguely remember ever putting it in program mode. Why does it work for single core apps but not for multicore ones? :?

Re: "on stdcore" malfunction?

It's on startup. I've made this simple example: #include <stdio.h> #include <platform.h> int main ( void ) { par { //on stdcore[0]: { puts("a"); } //on stdcore[1]: { puts("b"); } } return 0; } It runs fine without the stdcore, but crashes if you uncomment them. About the XN file:...
