Re: C library for raspberry pi 3

Yes, you can do that. Just follow the instructions on the website and you will have a working bcm2835 library.

But you should know that the wiringPi and pigpio are pre-installed in Raspbian, so they are ready to use.

There is no undo. It's permanent.
Yes, you can only undo the SD card, but not the Pi itself.

Re: Groundhog day

I had the same thing a while ago. As long as the Pi is on things are ok and you can read back what you have written. But somehow the SD card does not really keep that information, so when you turn off power everything is gone. Get a new SD card and try to copy any important files from the old one, t...

Re: Debian 9 Stretch announced, Raspbian's future

Contradictory information :lol: I did apt-get update on my weather station Pi (1B) and after a reboot it now runs kernel 4.9.24+. update doesn't install anything new. You must have done an upgrade or dist-upgrade to get the new kernel. Yes, you are right: apt-get upgrade (slip of the keyboard).

debmirror will do the job. How much disk space is needed with debmirror? Does it download everything or does it just maintain the very latest packages?

Re: ? possible to have less #include and less build paramete

Geany can handle makefiles (see the Build menu), but you have to point to the right makefile of course.
Another option might be the Project facility in Geany. I haven't used it myself so far, but it could be a solution.

Re: ? possible to have less #include and less build paramete

This is probably more a question for the openvg developer, but you could easily make a headerfile that has all the necessary #includes yourself and #include that in your own programs.

The build command is not that easy but only a one time problem if you use a makefile.

I think it's just a matter of a dying power supply. 1 Ampere is a bit weak I guess.
