Free Claude AI's first attempt: "A programming course for the Propeller P1".

I may explore the prompt "create a programming course for the Propeller P1" further....
If nothing else, exploring the errors may be interesting.

Interesting to try... Got through half of first page...
Hmm... Don't think anything about P1 is 5V tolerant... Lost a lot of chips that way...
Also, think there is only on 32-bit I/O port that is real.
On page 1 it states 64 pins in the text (wrong), then 32 pins in the table (correct).
Agreed, and most had decided that an IO pin should have at least 3.9K in series to protect the diodes on each pin from experiencing too much current with a 5V signal. I use 4.7K because it's a common resistor value. The AI doc suggest that 100 ohms is sufficient. It's not.
What caught my eye was section 10.7. CNTRMODE %01100 is negative detect -- to my knowledge there is no direct quadrature mode. For grins, I copied and pasted the code into Propeller Tool. It runs, but just produces gibberish, not clear quadrature counts.
There is a danger in posting what Ada would call "AI slop" in the forums. It's a nice(ish) looking document and newcomers could be sent down very frustrating rabbit holes. There is quite a lot of human-produced (actual intelligence) material for the P1.
Good point Jon, I tend to think of the forum as all experts, but of course there are new users too. I will edit the post.
