Re: raspberry pi 3B underclock

I think this needs the engineer team to look at it. This is the point it goes wrong, as you know That second bit from the end goes to 1 and starts to override the settings, as though it's now *allowed* max frequency, hit 80.0C and throttles back. 22:03:29 79.5'C 900MHz 00100000000000000000 1.3V 22:...

Re: The much heralded "Buster"- When?

At the moment it's running mostly Stretch with a few bits from Buster. I have Raspberrys that are running everything from Wheezy to St...

I wonder if they'll ask for pre-release testers to get rid of a few bugs (iirc there where a few when Ra...

Re: ScriptBasic

From my point of view, I just see you as making it useful on the Pi, for whoever wishes to use it.

One though, if you use WiringPi, does that make it easier to port to Arduino type devices (that's an open question to anyone that knows).
I don't know what its benefits are over pigpio.

Ben, how's piwheels doing for 3.6/3.7 whichever ends up in Buster? (3.7 if it follows my RPDx86 "buster" test).
Is it all setup and ready?
