please help me with my project (ADC)
Hello, I hope I'm in the right place. I want some help to design a circuit converts four analogue variables (-12v to + 12 v) into digital signals and send it to computer. There are another 10 variables but they are only ON/OFF. The voltage for them will be 12v when they are ON and 0 when they OFF, so they need to be converted into 1 and 0 in order to be sent to the computer. I want to know: 1- Is it possible to connect all of these variables to the computer at the same time? 2- What components do I need? 3- What is the best way to have the most accurate results? 4- Which port will be used? 5- What is the best way to display the results on the computer? thank u |

Yes 2. depends on design 3. careful design with good resolution on the A to D convertor 4. Any one you want 5. On the computer screen. Do you really expect someone to do a detailed design for you? Ask specific questions and someone may be able help. Otherwise there are cards you can buy that will plug in to the computer and bring in these values. -- Dan Hollands 1120 S Creek Dr Webster NY 14580 585-872-2606 www.QuickScoreRace.com |
