Atmega32u4 16 to 20 or greater.
Might gain just enough logic and speed via CCL.   Correct me if I'm wrong but that is not an option for the mega32u4 ?

Yes, mainly for lufa support. I was not aware of the 8/16 but not surprised.

Atmega32u4 16 to 20 or greater.
It started here. And yes, that did work but it got even tighter as the timing is based on a "games". The project is to emulate a video game controller and in this case each game...

Yeah saw that a bit of an upgrade. Wish there was a better option with the same form-factor. I could also consider a co-processor for my issue.

Well that's that then.

help with ASM pin change.
I'm only guessing here but I'm think the break ?   if ((PIND & PULSE)==0x00) {  PORTC = _low_state_portc_first;   PORTD = _low_state_portd_first;  ...

simply rolling out the define to code allowed the timing I needed.   from this: timer =1; WHILE_PULSE_IS_HI;//find falling for second pulse PORTD =...

help with ASM pin change.
That sounds like nonsense...if the  AVR is raise/lower the lines, why would it need to read them?   Is reads the other lines? This protocal if you will uses a total of...

help with ASM pin change.
If I did a pin change it needs to call a function. So my issue is this.   current code timer =1; WHILE_PULSE_IS_LO; PORTD = _low_state_portd_second; PORTC =...

atmega32u4 partial functionality from port D pullups
Ok, was a user error, I guess I had a few traces on my breakout board that needed TLC. Thx for the explanation as always.

atmega32u4 partial functionality from port D pullups
Right so I need to do just that, the PORD register needs to drive low on the pins to show the state to another MCU.  I start to notice that the PINS were not going low when I...

atmega32u4 partial functionality from port D pullups
Yes I typed D instead of P and copied an pasted to replicate my error.   I though the pull-up/downs were PORT's? "Anyway pull-up/downs are only for inputs. " -So PORTD...
