How Much Do Tombstones Cost

LabView DAQ by CDC and Guitar Hero

This is an application of USB connectivity in this particular case, using the emulation RS232 serial port using a PIC18F2550 microcontroller (You can use any of this family) to acquire analog data using analog-digital converter of the same, and sending this data to the PC and processed by LabView.
With LabView can do a lot of awesome things, and most impressive is the implementation time is very short, in minutes you can get a pretty powerful application.

used for this application components labview VISA for serial connection quickly but effective CHART GRAPH is used to plot the acquired data, and function to WRITE TO SPREAD SHEET save this data to a spreadsheet exel.
