Hi,
I'm trying to use printf in the application 'RadioCountToLeds' running on
top of tinyOS-2.0.2. I have some problems with wiring interfaces of printf.
I have modified RadioCountToLedsAppC.nc as follows:
*configuration RadioCountToLedsAppC {}
implementation {
components MainC, RadioCountToLedsC as App, LedsC;
...
components PrintfC;
App.Boot -> MainC.Boot;
...
App.PrintfControl -> PrintfC;
App.PrintfFlush -> PrintfC;
}*
I have also modified RadioCountToLedsC.nc as follows:
*#include "printf.h"
module RadioCountToLedsC {
uses {
...
interface PrintfFlush;
interface PrintfControl;
}
}
implementation {
event void Boot.booted() {
call PrintfControl.start();
call AMControl.start();
}
...
event void PrintfControl.startDone(error_t err) {
// do nothing
}
event void PrintfControl.stopDone(error_t err) {
// do nothing
}
event void PrintfFlush.flushDone(error_t err) {
// do nothing
}
event void MilliTimer.fired() {
counter++;
dbg("RadioCountToLedsC", "RadioCountToLedsC: timer fired, counter is
%hu.\n", counter);
printf("RadioCountToLedsC: timer fired, counter is %hu.\n", counter);
call PrintfFlush.flush();
}
*I have modified the Makefile to include $(TOSDIR)/tos/lib/printf/2_0_2 in
the CFLAGS.
When compiling for micaz, I get the following errors:
*mkdir -p build/micaz

I cannot find the tutorial modules (TestPrintf, etc.) for printf 2.0.2
release.
Does anyone have an idea about what is wrong?
Thanks,
Vincent
