Noticed I don't have to use PSTR now for string constants. And, I can initialize constants where they are declared. Using gcc 4.5.3

These statements work fine -

printf("Switch Cntrl");

volatile uint16_t wave_events[WAVE_EVENTS]={1000, 9000, 1000, 9000};

Any reason to keep coding the old way?

I meant initialize variables where they are declared ...

Noter -

Are you using this string in your makefile...

avr-objcopy -j .text -j .data -O ihex

I think that lets you get away with the array initialization. As for the "printf", I always thought PSTR was used in the "printf_P" family of functions. The only downside of "printf" is the strings get stored in RAM I believe.

Yes, I do have that in my makefile. You are correct, I eventually ran out of ram so even though it works a few kb is not much space. Went back and changed to PSTR's and all is well again. Thanks for your post.
