24b8vin-rpi

Drivers for Eight 24-Bit Analog Inputs DAQ 8-Layer Stackable HAT for RaspberryPi

Setup

Enable I2C communication first:

sudo raspi-config

A good article about I2C on Raspberry can be found here.

If you use Ubuntu you need to install raspi-config first:

sudo apt update
sudo apt install raspi-config

Make sure you have all tools you need:

sudo apt update
sudo apt-get install git build-essential

Usage

Install the command:

cd
git clone https://github.com/SequentMicrosystems/24b8vin-rpi.git
cd 24b8vin-rpi/
sudo make install

Now you can access all the functions of the Eight 24-Bit Analog Inputs DAQ through the command "24b8vin". Use -h option for help:

24b8vin -h

If you clone the repository any update can be made with the following commands:

cd ~/24b8vin-rpi/  
git pull
sudo make install
