cas-rf-poe-adc

This repository contains iocs for the adc/spi hardware developed by the RF group. We start two systemd services, one for the IOC and another for a Python script that is used to get data in and out from the board.

[IOC] <--------> [.py] <---> [hardware]

Requirements

The python script requires the module Adafruit_BBIO.

Install it via pip or manually:

#  via pip
sudo apt-get update
sudo apt-get install build-essential python3-dev python3-pip -y
sudo pip3 install Adafruit_BBIO

# from the repository
sudo apt-get update
sudo apt-get install build-essential python3-dev python3-pip -y
git clone git://github.com/adafruit/adafruit-beaglebone-io-python.git
cd adafruit-beaglebone-io-python
sudo python3 setup.py install

procServ is required for runing the IOC.

apt-get install procserv
