Didn't know Dr Jones driver was 85 based - actually totally forgot bout it. Soo hard following his stuff - I always seem to have a broken link to his sites. Think it's mentioned here: https://budgetlightforum.com/t/-/23510.
Edit: If he reads what we go thru, he's probably sitting back laughing - he knows all this stuff: been there, done that... 
We are breaking ground in making it public I suppose. Others, maybe many others, have gone through all this already. Remember the polish driver? 25 based I think.
The wikipedia article is definitely mis-leading. It shows no difference in PWM support between the 13 and 25/45/85's... Wow.
