Let's say im absolute amateur in microcontrollers.
I'm working on a project to measure the inclination with accelerometer..
I tend to use analog output ..I picked the Adxl330 with -/+3g (3axis)..Suplly voltage would be 3V in my case..
Is enough to utilize only one Axis to get a tilt?
Im strugglin with op amp follower..
The output impedance of adxl is 32kOhm..The ADC is optimized for analog signals with an output impedance of approximately 10 kΩ..
What should i consider now?
Resolution?
Noise? There are few hints how to cancel analog noice in the datasheets for atmega8.
I need some direction where i should look ..any ideas?or recommend me site/book where i can find more about the ADC problems..Which ive visited yet,haven't told me so much..
