Indirect addressing error created by the compiler
What were the values at 0000542B? If they really are getting trashed in that routine, then simply trying to cause a reload isn't addressing the cause, just a symptom. Can you use...

Indirect addressing error created by the compiler
So when you stop at 0000542B, R28=0x0F and R29=0x1B, but when you step over to 0000542D, R28!=0x0F and/or R29!=0x1B? What values do R28 and R29 have there? Be sure to actually...

Seeking authoritative reference for 100K EEPROM write limit
What's the difference between it being byte-based versus array-based? Rewriting each individual byte 100K times and rewriting the array 100K times is the same thing at the byte...

Header library setup
If you had avr/a.c avr/header.h avr/header.c Then in a.c you can just do #include "header.h" and have it find the file. If you had avr/a.c avr/header/header.h avr/header/header.c...

value limits
Are you illustrating why one would want to use a minimum of -127 rather than -128, because negation would otherwise potentially overflow?

Capturing and decoding a fast (but short) Manchester signal
This thread was sticking in the back of my mind as a fun challenge, especially since people were saying that a 20 MHz AVR might need hardware assistance. So I whipped up a decoder...
