Format Date and Time using sprintf?

Lakes:
Can someone post how to do the same with the sprintf function?
I`m curious to see how much memory (if any) using the sprintf saves, instead of doing several serial.prints.

Thanks.

If you're worried about using up RAM, you've got to see THIS library: Flash | Arduiniana

I recently wrote a 4 channel solenoid valve controller program that has an extensive user menu (LOTS of text). I ran out of memory in a "flash" (pun intended). :slight_smile:

By using the Flash library, most of my SRAM is now unused and available.

Here's a piece of the code to show how the Flash library is used:

	FLASH_STRING(menu,
		"\r\n"
		"  Four Valve Independent Controller - Main Menu\r\n"
		"\r\n"
		"  Please select an option\r\n"
		"\r\n"
		"    (1) Run controller\r\n\r\n"
		"    (2) Configure valve timing\r\n\r\n"
		"    (3) Review all valve timings\r\n\r\n"
		"    (4) Change serial baud rate\r\n\r\n"
		"    (5) Display free memory (debug)\r\n\r\n"
		"    (6) View license information\r\n\r\n"
		"    Option: "
	);
	menu.print(Serial);

SRAM used for this code: zero!

Hope this helps......
