Is it cooperative scheduling
You should declare a global volatile unsigned long variable (for example: milliCount) and initialize it to 0x0000.  Then set the timer to interrupt every millisecond and...

USART waveform question
I don't believe that the formula for baud rate is correct.  I know...I know...the datasheet says ...  But, at this point, I really don't trust anyone at Atmel to write...

Interrupt to toggle LED
If you want to clear DDRD2, use void INT0_Init (void) { DDRD &= ~(1 << PD2);  I, also, suspect that this is a bouncing push-switch.   You can add a...

AVR DB - GCC - first experiment with interrupt (from USART0), appliation restarts when first character received by USART0
Your main() loop should actually have a loop in it, like   { while(1);  }  after the sei().  Otherwise, main() simply executes random instructions after...

Coping with global chip shortage - any guess what microcontrollers will have best future availability?
 My approach to the shortage of parts problem is to design every project (and subsequent product) on four multiple hardware platforms. And I use the Arduino IDE because I can...

Hoping for help on a tiny issue with I2C
This is most likely not a hardware problem.  Your RasPie is sending I2C address 0x00, which is a special reserved case.  No I2C devices or slaves use address 0x00. Make...
