Servo motor doesn't go to 0 #8

Closed danowall closed 6 years ago

danowall commented 6 years ago

In MakeCode, servo motor doesn't go all the way to 0 degrees when "crickit set servo angle to 0" is used.

Using "crickit set servo pulse to 500" does send servo to 0 degrees, however.

this isn't a bug, this is just how servos work :) https://learn.adafruit.com/adafruit-crickit-creative-robotic-interactive-construction-kit/makecode-servos#precise-pulses

got it! thank you for these links, this is helpful.

hey @ladyada did we test that setAngle gives the same results as the corresponding function in cirpy or arduino?

ladyada commented 6 years ago

we didn't but we can. in cirpy you can adjust the min/max pulse in the servo library and i did that a lot. we also default to 1-2ms in circuitpy https://github.com/adafruit/Adafruit_CircuitPython_Motor/blob/master/adafruit_motor/servo.py#L43
