Re: Raspberry Pi 3 (can i double the processor power?)

You might like to follow this recent and still evolving forum discussion.

But the short version is that there isn't a trivial way to meaningfully increase the cpu power of your existing RPi.

Re: Something new

It would be great to have some semi-permanent memory on board RasPi. A note of disagreement here. Having no non-volatile memory (modulo a small handful of OTP bits) is ideal for support and troubleshooting. It means that every machine is, prior to power-on, always in the same factory-fresh conditio...

My hunch is that it would be necessary to examine the Example_Program library module you are using, in particular the ex_read() function that is repeatedly called by both example scripts. Could it be that ex_read() is opening a file handle on each call but not closing it, so that eventually you exha...
