I am interested in hooking up a nano to an RC receiver. I want the nano to mirror the PWM input and output on another pin when a specific command is given via serial. I also want to send the received command via serial to a computer(Pi or Jetson) at the same update rate.
I can run pin change interrupt on the input pins to basically enable/disable the pins but I'm wondering if there is a better way.
I also will be updating a motor encoder at pin change interrupt, I'm guessing around 4k interrupts/second.
Do you think the Nano provides enough juice or I should use a Pico?
