Once written and reused, code works best in a library. Here I describe the first steps to create and use a library.
In one of my last posts I explained how the watchdog of the RevPi Connect can be used. If you look into our tutorial, there is also an ominous EEPROM mentioned.
Tired of screw terminals. In this post I give you a quick hint, how to get push-in terminals for the Revolution Pi
A watchdog is an important tool for ensuring availability, especially for unmonitored systems. Here is how to activate the watchdog.
For regular operation, the RevPi usually has to start all necessary software itself. The means of choice for Debian-based systems is systemd.
An understanding of background processes is almost essential for the productive use of RevPi. Therefore a short outline of background processes under Linux.
Shutting down the RevPi is important, as with any modern computer. Therefore I give a short overview about shutting down a Linux system.
Sometimes it can be very useful to execute commands on the RevPi without having explicitly started an SSH session before. OpenSSH and Putty can therefore be given commands to execute.
How to set up OpenSSH on Windows as an alternaitve to Putty.
In order to save myself the continuous typing of the password, I configure the authentication via key at Putty.
Here I make my first steps with C/C++ on the RevPi and demonstrate how to control outputs and read inputs.
In this article I show how Netbeans can be used on the PC as development environment for the RevPi.
My name is Thomas, I work in sales at Kunbus. In this blog I write about my experiences with the Revolution Pi.
