AVR-Chat

I have kind of had this problem for a little while, I am assuming your 
accelerometer is on from Analog Devices and also outputs a PWM wave just 
like the analog signal. I haven't figured out a way to measure like 4 
PWM waves, out of phase (possibly) in my application. I am afraid that 
when I do the counting, an interrupt might occur and I will have obscure 
results. I cannot disable the interrupts temporarily because the 
interrupts are needed, all the time (one of them generates PWM signals 
for servos, the other counts encoder clicks, etc) I am implementing this 
on an ATmega16. Does anyone have a clue as to how I would go about it?


Is there a way to filter the noise from the motors out of the Accel
signal through CodevisionAVR?

I think you could average your results, do you need to have a high 
sample rate? It also might be the AVR's internal ADC, the motor migth be 
generating a lot of noise on the power supply
