TLC 549 Voltage Logger at the serial or parallel port

voltage logger project

Hi,

How can I build a 0-15V voltage logger using TLC549 and the serial or parallel port of my PC? Is there any software ready? Can I modify to my language (portuguese)?

Regards,

Hi fjpompeo,

I'm not sure whether this would help. I've came across a parallel port based oscilloscope project in an electronics R&D magazine: Electronics For You .
The article is available as a pdf file through the following link:

www.electronicsforu.com/efylinux/circuit/dec2002/circuit1_oscilloscope.pdf

It is based on ADC0804.You would need to scale your input to 0-5V. A 'C' program is given in the article and you may modify the string constants to your language.[/url]
