PyRedPitaya 1.0

Python utilities for redpitaya

Overview

This package provides a library to access the Red Pitaya registers. This library consist of a C library (libmonitor.c) and a ctypes interface on the Python side.

An object oriented interface to the different application (scope, generator, PID, AMS, …) is provided. This interface is implemented using Python properties (see usage below) and can quickly be extended to your own application.

An rpyc server is used in order to communicate with your computer. The interface is the same on the computer as the one on the board.
