Re: Accessing GPIO I/O Pins from Forth

The way I see it: something like the RPi really shouldn't need protecting from users (cos it's meant for users to get at). However, if we insist on also having them connected to Internet threats, protections become necessary - which can be circumvented by "sudo" (whether it happens to be needed or n...

Re: Accessing GPIO I/O Pins from gForth

Hardly a problem though, is it? I was proposing to say something like "if you are using the full version of Raspbian you don't need to do (whatever)". Covers all bases.

Re: Accessing GPIO I/O Pins from gForth

Thank you both. Yes, there's no need for desktops and office apps for the kind of usage I have in mind. Good to know though, and I will make a note of it in the primary post when I have had a chance to test (not that I doubt you, but I do like to confirm everything if possible).

Re: Accessing GPIO I/O Pins from gForth

Does that mean As I understand it, we need a special version of the wiringpi libraries, so need to get rid of any existing (if they exist): sudo apt-get purge wiringpi hash -r (I don't know what the "hash -r" command is for.) Now install the right version of the wiringpi libraries: sudo apt-get inst...

You shouldn't need to purge Wiringpi. The Stretch version is 2.44 which is current and works with all models of Raspberry.
Thanks, appreciated. I'll try it from scratch without.

Re: RasPi as universal Remote

Hi guys, I have just joined this forum specifically to reply to this topic (I realise it is a bit stale). I have been thinking of joining the RPi revolution, and as it happens I had an idea about using one as a universal remote... hence Google brought me here. I shall be reading up all the stuff alr...
