Thanks for the prompt reply. This is the code of the open loop that I run, it is the example with some minor changes:
// Open loop motor control example
#include <SimpleFOC.h>
// BLDC motor & driver instance
// BLDCMotor motor = BLDCMotor(pole pair number);
BLDCMotor motor = BLDCMotor(7);
// BLDCDriver3PWM driver = BLDCDriver3PWM(pwmA, pwmB, pwmC, Enable(optional));
BLDCDriver3PWM driver = BLDCDriver3PWM(9, 5, 6, 8);
// Stepper motor & driver instance
//StepperMotor motor = StepperMotor(50);
//StepperDriver4PWM driver = StepperDriver4PWM(9, 5, 10, 6, 8);
//target variable
float target_velocity = 0;
// instantiate the commander
Commander command = Commander(Serial);
void doTarget(char* cmd) { command.scalar(&target_velocity, cmd); }
void doLimit(char* cmd) { command.scalar(&motor.voltage_limit, cmd); }
void setup() {
// driver config
// power supply voltage [V]
driver.voltage_power_supply = 12;
// limit the maximal dc voltage the driver can set
// as a protection measure for the low-resistance motors
// this value is fixed on startup
driver.voltage_limit = 6;
driver.init();
// link the motor and the driver
motor.linkDriver(&driver);
// limiting motor movements
// limit the voltage to be set to the motor
// start very low for high resistance motors
// currnet = resistance*voltage, so try to be well under 1Amp
motor.voltage_limit = 3; // [V]
// open loop control config
motor.controller = MotionControlType::velocity_openloop;
// init motor hardware
motor.init();
// add target command T
command.add(‘T’, doTarget, “target velocity”);
command.add(‘L’, doLimit, “voltage limit”);
Serial.begin(115200);
Serial.println(“Motor ready!”);
Serial.println(“Set target velocity [rad/s]”);
_delay(1000);
}
void loop() {
// open loop velocity movement
// using motor.voltage_limit and motor.velocity_limit
motor.move(target_velocity);
// user communication
command.run();
}
