Has anyone seen a port bit fail?
For now make sure that the internal resistor is enabled in the FW :)   100k should be fine, unless it's a long wire, but if the driver (from the outside) can pull 10k...

Under what circumstances would you *NOT* want to use the BOD?
BOD use power, so battery powered things could benefit from having it disabled.

Help with DDS and PWM
please show the code you use (inclusive, sine-table and how you make the trigger signal).(any other ISR's enabled?, empty main ? how "empty" :) )   How long does the ISR take...

Problems after upgrading GCC compiler to 9.1.0
I don't want to hijack this thread but does the compilers handle __flash as memory mapped, or does they still use LPM ? One would hope that 9.1.0 would do it (it should make...

Quiz for fun, I/O pin and 4 levels
About where the code run , back in the old days (I think it was late 80's), one of my friends had a PC (80286 I think), that had a LED bar on the case, that showed where the code...

Help with DDS and PWM
This is not a filter fault !  If a filter makes it better it's because it blur the sw error. Find the error first.

Which is faster: internal EEPROM or External EEPROM?
Why the internal and I2C compare , I would look at SPI EEPROM(or FRAM)

Help with DDS and PWM
I would also go with a DDS, (it's just an other way to pick the needed value), and if scaled correct you can still get more values than in the table (just some will be the...

UART transmission every 5 minutes using Timer.
The code in #7 should work, but you should avoid the need of cli around sei code.   Keep the timer variables as statics in the ISR, and set a flag every time 300 sec is gone...

I'm confused you talk about: title is  receive only , but your link is to transmit only !

"structured assembler" for gas...
Remember that the ASM code also can be optimized, something like 20%(speed) (unless it has to be written in nice s'AVR)
