SDK • Re: troubletrouble defining a macro to replace a zero argument fn call: micros()

Code:

       #define DEBUG_PRINTF "Serial2.printf"

Those quotes are the source of your current problem, as it expands to:and hence the error that you are getting.

Can you suggest how I get a generalised DEBUG_PRINTF function call using inline fns?

Getting it is easy, problem is what to put inside it unless your Serial2 object has a vprintf() (or vfprintf()) in it.
You can kludge it with the generic vsnprintf() but then you need a temporary buffer of undefined size (admittedly, for a debug printf limiting the size probably doesn't matter, but it falls short of your original objective of just calling the target printf.

Another approach (untested) using a constant function pointer which should optimise away just like inline:
(obviously the typedef is unnecessary, you could declare the function pointer directly, but that makes it hard to read IMO).
