conditional compile debug output

[udo-munk]

When using the library I get debug output to the terminal, which is unwanted for 2 reasons:

1. it screws up the terminal output of my application
2. it needs memory space which is very spare in my project.

My application looks like this:

//#define DEBUG // enables some debug messages

#include <SPI.h>
#include "Adafruit_FRAM_SPI.h"

....
....

void setup()
{
if (!fram.begin(FRAM_ADDR_SIZE)) {
Serial.println(F("No FRAM found"));
exit(1);
}
...
...
}

So if I should run into problems with the FRAM module I can enable additional DEBUG output to see what happens. But only then and not in the production version of the software.

look good, thank you. I rebased and got a slightly change

Thank you, change is fine, in my application I can now do:

//#define FRAM_DEBUG 1 // enables FRAM debug messages
//#define DEBUG // enables some application debug messages
