Hello,
I need to measure an amplitude of a 60Hz sine wave (output from a Hall-effect sensor) using ADC on N+2. I am looking for elegant ways to accomplish this. What are my options?
Option 1: Is there a way to configure ADC to collect multiple samples with specified frequency?
Option 2: Can I use hardware-timer interrupt to take a sample every 4ms? Is timer implementation reliable (in terms of interrupt triggering accuracy) to rely on it for timing?
Option 3: Collect 100 samples over period of time and use histogram to reconstruct the sine wave.
Option #1 seem to be the best, but I don't know if Netduino NETMF supports that mode.
Any other ideas?
