So, you’ve developed a nice ROS application, which can be launched with a single launch file: great! But… There is still a problem. Actually you have to manually launch this file with a command line tool (roslaunch), and you wonder how you could make your application automatically start when you boot your computer… Or your … Read more
Raspberry Pi hardware permissions can be quite tricky. So, you are using hardware functionalities with your Raspberry Pi 4 (or 3B, 3B+), and always getting errors such as “Permission denied”? This might be the case if you use I2C, SPI, UART, or simply the GPIOs on the Pi, with a user that isn’t root. In … Read more
WiringPi is a Cpp library for Raspberry Pi. With this library you can use many of the functionalities provided by the GPIO header: digital pins, SPI, I2C, UART, etc. Although there are many Python libraries for Raspberry Pi GPIOs, Cpp is quite a bit behind. Fortunately, there is WiringPi. In this post you’ll install WiringPi, … Read more
In this tutorial I’ll show you how to use and compile WiringPi in your ROS Cpp nodes, so you can talk to hardware devices from your ROS application. Make sure to read this introduction to WiringPi before if you don’t know the library well. The WiringPi library is a great tool for Raspberry Pi (4, … Read more
In this tutorial I’ll show you how to communicate between a Raspberry Pi 4 (also works with 3, 3B, 3B+) and an Arduino (Uno), using the SPI protocol. The Raspberry Pi will be configured as a master, and the Arduino as a slave. On Raspberry Pi we’ll use the WiringPi library inside a Cpp code … Read more
