how to control “sg90” Steering engine？

“GpioPinValue pinValue = GpioPinValue.Low;
pin27 = gpio.OpenPin(27);
pin27.SetDriveMode(GpioPinDriveMode.Output);
pin27.Write(pinValue);”
but sg90 does not work。

It's a servo motor.

You need to generate servo control pulses on the signal wire (orange).

I recommend you start with pigpio.

You can read about pigpio here:
http://abyz.co.uk/rpi/pigpio/

For a quick test, start the pigpio daemon:

Code: Select all

sudo pigpiod

Then use pigs to generate the servo pulses:

Code: Select all

pigs SERVO 27 1500

Here, 27 is the GPIO number, and 1500 is the pulse width in microseconds. 1500 represents the "centre" position of the servo.

Slight problem, pigpiod and pigpio is Linux only, it doesn't exist on Win10 IoT.

You know, you're right. The sub-forum is not easily visible on the "New Posts" page. I'll double-check that next time before I post.

Anyway, maybe someone can help with Win10, or maybe the original poster will try Raspbian.

perhaps can help: two projects make use of SG.
