RET function returning to beginning of code instead of CALL point
The phantom text doesn't show up in the quote box either, but it does show up on my screen.   Now, it's hard to tell with all the jumping and branching around, but I strongly...

ATMEGA32 minimal PCB circuit
Cute lil' PCB, kabasan, but I'd have given the caps their own layout instead of having to glue them to the pins later on.  I do like the GND test point, though - I put them...

Help for Assembly Newb
Interesting inconsistency (hobgoblin of little minds?):   The ldi R16 is in decimal. ldi R24 and ldi R25 is in hex. sbiw R24 is in decimal again. [dec r16 doesn't care]....

CD4026 based timer clock - how to reset the clock at startup and on demand
0.1uF (== 100nF) axial monolithic caps can be very prettily tacked diagonally across the chip on the back of the board.   I'm not quite as down on 'netlists as schematics' as...

When do you think that interrupts become very important
If it is important that your code flow smoothly forwards with consistent execution time, don't use interrupts (or turn them off).  If it is important that at some point your...

Trouble Writing to Parallel SRAM
The ceramic caps will do, and the new layout is MUCH cleaner than the old one.  I like that you left one electrolytic in there - but I'd have left it in the other corner,...

Trouble Writing to Parallel SRAM
It may have been misinterpreted that lots of little electrolytics (22uF or so) are better than a few big ones.  And that's true, to some extent (they are better, for several...
