Re: [EE] Saving "printf" arguments for later? Real-time on slow processor.

Is it possible for you to replace que calls to 'printf' with calls to 
different functions depending on the specific formatting?

If so, each function would know exactly what it is receiving as 
parameters and simplify the saving of the data. Those functions could 
even receive an additional parameter telling them if they should save 
the parameters or printf them.


Cheers,

Isaac
