What if i want to use two rotary encoders on UNO, NANO etc?
I building a frequency generator, with ad9833 the output will also be plugged in pin 5 to use freqcount and measure it.
The generator will have an encoder to increase/decrease frequency, and another to change the scale (x1,x10,x100,x1000...) the first encoder will increase 1*scale.
So i faced the problem that all examples using rotary encoders, uses pins 2 and 3 (on nano) which are the only interrupt pins, if I use any other pins, will it be a problem? (i only have one rotary, but more are on the go, so i cant test yet)
If its a problem, how to solve it? i saw one library that clains to use 4 rotary encoders at same time, but, some parts of the code have conficts with freqcount.
the main question its, why its needed to use interrupt pins? i mean, if the behaviour its like a push button, i can use a push button on any pin, why not rotary encoder "push button"?
PD: encoders are EC11.
