If you have just logged on to the labview online evaluation, you will first need to configure your measurement system. Indicates whether the download includes 32 or 64bit software. Labview is systems engineering software for applications that require test, measurement, and control with rapid access to hardware and data. This is your development environment where you will write your computer program to control the chipkit device uno32. Download and install labview 20 if you do not have it.
Simple pulsewidth modulation switches the leds on and off more quickly than the human eye can discern. In this project, students learn the principles of operation of an led matrix, and techniques for displaying patterns and animations. Labview 64bit does not work with all toolkits supported by labview 32bit. Thats why in this tutorial i will focus on describing labviews interface as well as creating first application blinking light. Is there a option in labview to give a led three or more colors.
