please advice someone to help me select correct rotary encoder, more likely its number of steps per revolution.
Wanna build tracked robot, each drive own actuator, shaft (with encoder) max. 120RPM
I would like to use Arduino Due due to clock freq. and number of interrupts.
And here is coming my unclear point, cosidering that each encoder will use two interrupts, 2 * 2 = 4
Encoder like this one:
Can be selected with resolution from 100~600 pulses per revolution.
Considering 120RPM so 2 revolutions per sec. so:
2 (revolution) * 100 (pulses) * 4 (interrupt pins) = 800 interrupts per second:)
2 (revolution) * 600 (pulses) * 4 (interrupt pins) = 4800 interrupts per second:)
If you still follow my flow, question is simple, will be 70Mhz clock speed able to handle 4800 interrupts per second reliably? Or should I rather go with 100 puls resolution?
Does it gonna work at all?
Any feedback appreciated! Cheers Mira
