“Continuous rotation servo - Fitech FS90R v2.0
The FS90R has been tested using a ESP8266 MCU with micropython firmware.
Simple to control with Increased dead band ( this with the SMD potentiometer is the main difference with the version 1.0)
To make a quick test I have used the same micropython code built to run&test 180 degrees servos. The 180 degrees middle point becomes the middle point of the Neutral Point range of crServo. In this case I have found that the duty stop range of :
76 78 the rotation is - clockwise (*) with a max reverse speed at 120 , with a simmetrical behavior of the rotation speed
I can easily control the speed value and the speed direction of the crServo. In a following step I' ll define a relation between the duty value and the servo RPM or % of max speed value . Anyway , the uPy code permits to control easily both, direction and speed.”
