printf with floats
Posted: Sun Mar 12, 2017 4:17 pm
Hi everyone,
Very quick question, in case you guys have seen this before: can't print floats on debug port using printf (not iprintf for integers, just the regular printf).
Using SBL2e, NBEclipse Release 2.8.2, I have my debug port on Serial 1. Here's the code:
And the output is:
Application started
My float = f
I tried everything, changed the format specifiers, etc. to no avail.
Any hints?
Many thanks!

printf("Application started\n");
float myFloat = 1.2345;
printf("My float = %f\n", myFloat);
while (1)

}
}
