I am writing code to read and control the 25mm DC encoder motor using the encoder motor driver/motor that came with the Ultimate kit. I have this code:
#include “MeMegaPi.h”
MeEncoderMotor motor1(PORT3B);
uint8_t motorSpeed = 100;
float position;
void setup()
{
}
void loop()
{
position = motor1.getCurrentPosition();
}
And it throws these errors:

Has anyone had any luck with using the DC encoder motors? I’ve gotten them to work as DC motors, but I want to control and read their positions for better control
