Hello everybody
I want to make usb button box for flight simulator. How many rotary encoders can I connect to the Pro Micro at most? They are 3 pin incremental encoders. I want to use as much rotary encoders as possible and use the rest of the pins as momentary switches. Can anyone help me with this?
how fast are the rotary encoders generating pulses?
it would probably be a good idea to move to a microcontroller with hardware QEI support, e.g. have a look at the ESP32 RotaryEncoderPCNT library which uses the ESP32 Pulse Counter (PCNT) module
