ESP32 MicroPython and Parallax Servos
The book Robotics with the Boe-Bot discusses the CR servos and says that the signal should be high for 1.5ms, low for 20ms to center the servo. To change the speed, reduce the on time to 1.3ms for full speed clockwise and 1.7ms for full speed counterclockwise.
I would like to use the CR servos and standard servos with MicroPython on my ESP32 boards. I have available to me the PWM class, which takes a frequency and duty cycle, not up time and down time. What values should I use to control these servos?
MicroPython PWM docs are here: http://docs.micropython.org/en/latest/esp32/quickref.html#pwm-pulse-width-modulation
