Part 3: Measurement Setup

A project log for Computer Lab Box

This Lab contains all important tools used for developing on embedded PCs without the need to have the board next to you.

The third part of this project is the measurement setup. I don’t want to leave my PC to check some pins or LEDs. For this I want to have a simple web cam and a simple logic analyzer.

Camera:

For the camera I am using the “Raspberry Pi Camera Module V2” together with the software “motion”. How to install and setup the software I found here:

Logic analyzer:

For the simple logic analyzer, I will use “wiringPi” which is already installed by default in Raspbian. With this library I can check the pin status of the J8 header, without initializing the GPIOs before.

First I thought to program a better logic analyzer, but for the projects that I plan in the near future I don’t need a better tooling and if I would need something better, I would use “piscope” ( à http://abyz.me.uk/rpi/pigpio/piscope.html) on my “Raspberry Pi Zero W”. So that I don’t lose any performance on the main Raspi.
