Re: Aaccelerometer Readings

Thanks for such a great reply, it really helps.

I was just hoping you could expand one thing:

Why is this? I understand why "no" acceleration would register at 2.5v which in turn would be somewhere near 512 depending on the bias. So then if that's 2500 mV = 512, then wouldn't 2g at 3080 mV = 631?

What if I was working with a different sensor that returned 350 mV / unit (random number don't know if it exists), would I still be dealing with the full range of 0-1023 or would I have to figure something out like I just did above?



Thanks
