Re: Pie 2B op-system-SD card

Thank You Dougie for the answer.
Nice to see You are still around. :)
Downloaded the new image but I must buy a new SD card reader, that's why Linux couldn 't read it. I have the "etcher" installed. Cross your finges the Pie itself is still OK.
Thanks

Pie 2B op-system-SD card

Hi Folks! I made a stupid thing, upgraded the op system directly from the Pi vers 2 B via WiFi and the menus on screen. After that the Pie will not start. I'm thinking to erase and rewrite the SD card with the old op-system, I have an old image file. But how to do that ? Or where to download the old...

Hi! This is maybe a newbie question and wrong thread? I'm writing a program to run some motors and other things in python 3... for the Raspberry Pi 2 B.

I just forgot the:

GPIO internal pull_up shorted down safety

May bee a simple question but pleaze..... One of the GPIO pins is set internally to PULL_UP. The program reads status HIGH. OK. Then a machine/rod is moving and push a switch. The switch shorts down the GPIO pin to GROUND, this makes it to be LOW. The program reads the change and acts. The machine/r...

Re: Start pigpio d from inside an other program

Hallo again! Since I already used up 22 of the GPIO pins and use them all almost all the time, I think the short way to "index" the GPIO pin like GPIO=8 and then using pi.write(GPIO, 1) # set it high is not a good solution for me, does not make it simplier. I think I must/need to to use the GPIO num...

Re: Timers counting seconds

Thank You All.
It works.
And a friend of my mine wrote a small object/program/modul what so ever, and I can load it and number t(1), t(2) and so on.
But please don´t ask med how it works and I have not seen it/read it yet.
I can upload it later when I have it in my computer and tested.
Thanks again.
