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

If printf is a weak function I would replace it with a function that sends
the format string out the serial port, complete with the raw variables.
Then the format string can be applied to a function on a remote machine to
scan the string and variables into appropriate output strings.

Is that a practical proposition?
