pyrp3 2.0.2rc1

Python utilities for RedPitaya

pyrp3

Python 3 port (using 2to3) of PyRedPitaya library in the pyrp3 namespace.

Note: The following is a copy of the Readme from the original repo and might not work with this version of the library.

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.

A 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.

Installation

To install `pyrp3`` on any machine, run the command:

  pip3 install pyrp3

Usage

You need to have Python installed on you Red Pitaya.

Interactive Python

Logging onto the redpitaya using ssh, one can start the ipython shell and run :

    from pyrp3.board import RedPitaya

    redpitaya = RedPitaya()

    print(redpitaya.ams.temp) # Read property
    redpitaya.hk.led = 0b10101010 # Write property

Remote access

You need to install the pyrp3 package on your PC as well as rpyc:

    rpyc_server

On the computer (replace REDPITAYA_IP by the string containing the IP address) :

    from rpyc import connect
    from pyrp3.pc import RedPitaya

    conn = connect(REDPITAYA_IP, port=18861)
    redpitaya = RedPitaya(conn)

    print(redpitaya.read(0x40000000)) # Direct access

    print(redpitaya.ams.temp) # Read property
    redpitaya.hk.led = 0b10101010 # Write property

    from time import sleep
    from pylab import *

    redpitaya.scope.setup(frequency = 100, trigger_source=1)
    sleep(100E-3)
    plot(redpitaya.scope.times, redpitaya.scope.data_ch1)
    show()
