I didn't see any posts about this, please forgive me if I missed something. I was curious why the servo.h library is limited to 2 servos on pins 9 and 10. The description page states:
This library uses functionality built-in the hardware on pins 9 and 10 of the microcontroller to control the servos without interfering with other code running on the Arduino.
I'm curious what the built-in hardware that allows this functionality. I know pins 9 10 and are capable of PWM output (which is not appropriate for running servers directly) but so do 3, 5, 6, and 11. Could servo.h be modified as such, around line 35:
static uint8_t attached3;
static uint8_t attached5;
static uint8_t attached6;
static uint8_t attached11;
Giving control of 6 servos?
