I worked really late on the next chip's universal dac/pin/video shifter and I just got up. I notice there are several more pages of ruminations without any confirmation, yet. Should be very soon.
Since we've got a coupla hours, how did the shifter code play out Chip?
It was like a massive headache which went on for days and then suddenly abated when things abruptly snapped into place.
We've got one simple state machine to handle shifting hub data in and out through pins and DACs. It also handles the Goertzel NCO and summation. It's good for video, fast analog output, fast pin I/O, SDRAM interfacing, and DSP.

Q: What is the fastest ADC input sampling rate, at how many bits?
This state machine is not useful for tallying ADC feedback bitstreams. That is handled by the pin, itself. You configure the pin and then poll it for samples of whatever size you wanted.
The pin takes 256 clocks to gather an 8-bit sample or, generally, 2^n clocks for an n-bit sample. You can have it do 1,000 clocks for a 0..1000 result, if you want, or any other sample size. No need to stick with powers of two.
I wonder if this announcement will cost me money.....should I run to an ATM in the next 30 minutes? Distract the wife so I can get to the cookie jar over the stove? Tell my kid she'll need a bigger scholarship?

Maybe we should all just start calling! Shake it loose! Somebody will give in, I just know it. Let's see, Ken, Chip, OBC, speed dial here we go....
Mind control....
It's like those "Hey I made a thing" sound tracks! With the perfect title.
I wonder if we will all be disappointed when the announcement is finally made since it will stop all of the theorizing?
It's all in fun. We will know soon enough. Maybe sooner.

LOL. We wish!

Very nice. Glad it all clicked Chip! Keep up the good work!
It's free.
1. The distributors were told on Monday.
2. It's free.
My guess: a significant change in business direction for Parallax.
Patience ;-)
