Servo Motor not working

❔Questions

Also, I suggest updating to latest Totem Boards “2.0.14-totem.1”. Version “1.0.0” is 2 years old and you may encounter some more issues down the road.

Same example code for latest version:

#include <Arduino.h>

void loopPositionRead() {
  // Print current servo motor position
  Serial.printf("Pos: %4d%%, Angle: %3d, Pulse: %4dus\n", 
    Servo.A.getPos(), 
    Servo.A.getAngle(), 
    Servo.A.getPulse()
  );
  delay(100);
}
// Initialize program
void setup() {
  // Start Serial Monitor communication at 9600 speed
  Serial.begin(9600);
  // Start parallel loop to print current motor position
  addLoop(loopPositionRead);
}
// Loop program
void loop() {
  // Simple motor spin
  Servo.A.spinAngle(0); // Spin motor to angle 0 (degree)
  delay(500);
  Servo.A.spinAngle(90); // Spin motor to angle 90 (degree)
  delay(1000);
  // Inverted direction motor spin
  Servo.A.setInvert(true); // Enable motor spin to opposite direction
  Servo.A.spinAngle(0);
  delay(500);
  Servo.A.spinAngle(90);
  delay(500);
  Servo.A.setInvert(false); // Disable direction switching
  // Set custom RPM speed for positioning.
  // Maximum speed is determined by motor capabilities.
  // Typically it's around ~60rpm.
  // When speed is set, getPos() function will return exact motor
  // position at the moment.
  Servo.A.setSpeedRPM(10); // Set motor spin speed to 10rpm
  Servo.A.spinAngle(0);
  delay(2500);
  Servo.A.spinAngle(90);
  delay(2500);
  Servo.A.setSpeedRPM(0); // Set back to maximum motor speed
  // Spin for specified length of time.
  // This function will spin motor at speed required to reach
  // specified position at given time.
  Servo.A.spinAngleDuration(0, 2000); // Spin to position 0 in 2 seconds
  delay(2500);
  Servo.A.spinAngleDuration(90, 1000); // Spin to position 90 in 1 second
  delay(1500);
}

Another servo example: Servo getAngle always gives 180 - #6 by Arnas

Edit: talking about issues… Just spotted that function “getAngle()” may return incorrect value sometimes. Will fix in next release.
