Hi!
I liked the new idea with printf! The split phase method is no more here and it
is good. But the small change of the standard example still doesn't work.
File: $TOSROOT/apps/tests/TestPrintf/
--------------
event void Boot.booted() {
printf("Hi I am writing to you from my TinyOS application!!\n");
printf("Here is a uint8: %u\n", dummyVar1);
printf("Here is a uint16: %u\n", dummyVar2);
printf("Here is a uint32: %ld\n", dummyVar3);
printfflush();
// BEGIN
while (1) {
printf("123\n");
printfflush();
}
// END
}
----------
It prints nothing at all. In the old version of printf I've used variable
locked to be sure PrintfFlush.done() was already called.
---------------
while (1) {
if (locked)
continue;
---------------
locked was released in .done()
This didn't help.
I guess I'm doing something wrong, but what?
I plan to use printf() for debugging or there is a better way?
Best regards,
Andrey
