QUESTION
Here I am trying to control my sg90 servo with a slider GUI made with Tkinter and sending the current value of the slider to Arduino over serial. Now the problem is whenever say, I'm moving the slider from 72 to 77 rapidly, the value it shows in the serial monitor is 7374757677.
here is the python code:

Instead of sending the data as a string by encoding, I sent the data as an integer in bytes format.
QUESTION
i am currently in the process of learning C# and the first thing i tried is to build an universal app, run it on Windows 10 IoT and to control an Servo Motor by it. My idea is to have an slider which controls the direction of the servo. For controlling the servo i use the NuGet plugin Magellanic.ServoController (by Jeremy Lindsay)
The calculations and movement based on the slider is working fine, the only issue i have, is that when i execute a movement of the servo, this process takes 30 % of the CPU capacity (event when the movement is completed). This results in the situation that i can execute 3 Movement and after this the CPU is at nearly 100 % and the 4th movement will not be executed correctly (as hardware i use a raspberry pi 3).
This is the code i use

Answered 2017-Jul-12 at 06:37This issue looks like caused by repeatedly call this line ServoGpioPin = pwmController.OpenPin(ServoPin);
of ServoController.Connect()
method but I am not sure what's the underlying cause.
There is a workaround: Instantiate the ServoController
and call ServoController.Connect()
only one time at first instead of doing this work every time in MoveServoToCentre()
method. Code sample like this:
