UPDI programmer software for Arduino - compatible with avrdude
trusty_mike, looks awesome  -- thanks for that I've been off the AVR hobby for a few months.  Can't wait to get back and check this out.

Timekeeping - High Level ?
So I'm curious what they get out of the change in mode frequency.   Are they using that to track the growth rate?

avr-gcc and avr-g++ are deprecated now.
bounty increased to $2020   I have read through a good amount of the GCC internals document and spent a little time going through The existing code seems to use...

Timekeeping - High Level ?
Jim,   I assume you are not trying to use the external clock to calibrate your internal one.  You are just trying to correct the time. A simple way to do this would be...

Use of java and other languages
What language features are you looking for?  If they rely heavily on dynamic memory allocation or self modifying code then you may be out of luck.

Identify Autotune PID algorithm
The relay method mentioned in #24 seems like a good bet.  Astrom is well known in the controls world (IEEE Fellow I'm sure). Why not go read the referenced article and go...

Compiler optimization between different CPU widths...
Are you saying you want to simulate an 8080 procesor, your 8/6 bit target, and run it on 8, 16, 32, or 64 bit host? I usually use unions to deal with 16 bit broken down into hi...

What are examples of RTOS
From my perspective an RTOS is a unit of software that iintegrates a  hardware timer or clock to a scheduler to run jobs that need to meet deadlines.   The RTOS and...

Envelope Detection
OK.  I'm trying to get my hands around a model for the measured signal.   Are you saying your measurement looks like a(t)*n(t) where a(t) is the source signal you...

Envelope Detection
It's not clear to me if the carrier frequency is known or not.  If so, and you want to get the amplitude in the presence of noise, then one option is a matched filter.

avr-gcc and avr-g++ are deprecated now.
status: I can now build gcc for avr from checked-out git repo.  I have yet to figure out how to run an uninstalled gcc.

Generate random numbers at compile time
What system?  I use bash on Linux so I can do this:   $ echo gcc -DRAND1=$RANDOM -DRAND2=$RANDOM gcc -DRAND1=1452 -DRAND2=13352
