I think you can even use a timer to trigger ADC conversions if you need a specific sampling frequency (instead of changing the ADC clock prescaler). You don't need an interrupt for when the buffer is full. Just have the loop check with a if statement if there is enough data in the buffer to start prosessing it. Ideally you'd process the data as it is coming in instead of waiting for a lot of data, and the process I'll this data in one chunk. But this depends on your situation. | |

| Dec 21, 2016 at 9:42 | comment | added | Ayush | But will I be able to measure the time between any two reading? I want to get the frequency and so I need the time between any two data which I intend to keep fixed. So to be clear, I should store data by setting clock frequency and using free mode in setup and attach a function (to process data) to interrupt when the ring buffer is full, and do nothing of this in Loop? | |
| Dec 21, 2016 at 9:13 | comment | added | Gerben | Writing to EEPROM is probably too slow. Just store it in memory. You can set the ADC to run in free running mode, where it will continually measure the voltage. You can then attach a function to the interrup so it run whenever a conversion is ready. You can store the values in a ring buffer. So the interrupt will fill the buffer with new data, while the loop will process the data and remove it from the buffer. | |
