Are you sure your doing the tutorials for the XC-1A and not the XC-1? Also make sure your opening the example projects for the 1A and not the 1. The XC-1 has similar tutorials and I made the mistake of opening the 1 , not the 1A examples when called to do so when I started.

I wish I could provide more guidance!

Hi,

I am sure I am opening the xc-1a. Here is the code generated by the wizard for the concurrent led project, as you can see it is for the xc-1a. However the previous errors pointed out are there.


/*
============================================================================
Name : xc1a-concurrent-led.xc
Description : Illuminate multiple LEDs concurrently on the XC-1A board
============================================================================
*/

#include <platform.h>
#define PERIOD 20000000

out port cled0 = PORT_CLOCKLED_0;
out port cled1 = PORT_CLOCKLED_1;
out port cled2 = PORT_CLOCKLED_2;
out port cled3 = PORT_CLOCKLED_3;
out port cledG = PORT_CLOCKLED_SELG;
out port cledR = PORT_CLOCKLED_SELR;

void flashLED (out port led, int period);

int main (void) {
par {
on stdcore [0]: { cledG <: 1;
flashLED (cled0 , PERIOD);
}
on stdcore [1]: flashLED (cled1, PERIOD);
on stdcore [2]: flashLED (cled2, PERIOD);
on stdcore [3]: flashLED (cled3, PERIOD);
}
return 0;
}

Here is the code that I copied from the last post that is supposed to work, but only works once and does
not continue.


/*

#include <platform.h>
#define PERIOD 100000000
#define PERIODA 20000000
#define PERIODB 300000000
#define PERIODC 400000000

on stdcore [0] : out port cled0 = PORT_CLOCKLED_0;
on stdcore [1] : out port cled1 = PORT_CLOCKLED_1;
on stdcore [2] : out port cled2 = PORT_CLOCKLED_2;
on stdcore [3] : out port cled3 = PORT_CLOCKLED_3;
on stdcore [0] : out port cledG = PORT_CLOCKLED_SELG;
on stdcore [0] : out port cledR = PORT_CLOCKLED_SELR;

void flashLED (out port led, int timeout){
timer tmr;
unsigned t;
unsigned isOn = 0b01110000;
while(1){
tmr :> t;
led <: isOn;
t += timeout;
tmr when timerafter (t) :> void;
isOn = !isOn;
}
}

int main (void) {
par {
on stdcore [0]: { cledR <: 1;
flashLED (cled0 , PERIOD);
}
on stdcore [1]: flashLED (cled1, PERIODA);
on stdcore [2]: flashLED (cled2, PERIODB);
on stdcore [3]: flashLED (cled3, PERIODC);
}
return 0;
}

Again any help from anyone would be appreciated. It looks like it should work... Also would like answers to the other questions I posted previously.

Thanks.
