rescale analog inputs
Our analog inputs on the cRIO have a range from -10v to 10v.
Our accelerometer has an effective range from 0.6v to 2.4v That's 9% of the full range, which means you get 9% of the full accuracy. I was considering ways of rescaling it, and I was thinking a linear regulated 10v supply, a -10v supply, and an LM386 would be a good way to do it. However, before I go out and buy anything, i wanted to check with you guys. Is there a simpler way to do this? Is there something I'm overlooking? |
