Python utilities for redpitaya

Project description

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.

Installation

The process to install PyRedPitaya on the board requires the installation of Python first. See this link.

To install PyRedPitaya on the computer download the package and run the command:

python setup.py install

or use easy_install:

easy_install PyRedPitaya

Usage

You need to have Python installed on you Red Pitaya.

Interactive Python

from PyRedPitaya.board import RedPitaya

redpitaya = RedPitaya()

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

Remote access

You need to install the PyRedPitaya 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 PyRedPitaya.pc import RedPitaya

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

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()
