Script copied from original dymoprint page and modified to include LM280 usb device id 0x1005 and ttf paths changed. Also usb device class changed from 0x3 to 0x7.

• Install drivers from this repo by following these instructions.
• Check if Ubuntu detects the LM 280 when connected to computer and powered on.
• Run the script.

Analog-to-digital conversion and acquisition (Arduino DUE + Python)

Copied and translated from original published by Frédéric Legrand (archived copy).

1. Introduction

This page shows how to operate the analog-to-digital converter of the Arduino Due, in order to perform sampled acquisitions. The sampling will be done by interrupts triggered by a stopwatch. The samples will be transmitted in a continuous stream to the computer, in order to be plotted in a graphics window or to undergo various treatments.

The arduino code presented can be used as a basis for an on-board application dealing with audio signals.
