pi2meter project finished

Post date: Jan 12, 2016 1:30:55 AM

I finished moving my pi2meter project from my old site and re-writing it. I used the PWM output since it isn't used for sound output on the Zero. It's a much cleaner implementation this way. This also made it possible to get rid of the kernel module - the gpio utility from WiringPi can control the PWM output directly. Actually, I could've used it in the old project instead of a kernel module. Sometimes I get carried...

I also added code to make it possible to display data from a data.sparkfun page. So now it's an internet connected meter!

Oh, and I learned how to do curve fitting on LibreOffice. Although it doesn't seem to work. And I learned how to use bc, the command line calculator. And how to use data.sparkfun.com. All together a productive weekend!
