We live in very exciting times 😃! BLDC motors are entering the hobby community more and more and many great projects have already emerged leveraging their far superior dynamics and power capabilities. BLDC motors have numerous advantages over regular DC motors but they have one big disadvantage, the complexity of control. Even though it has become relatively easy to design and manufacture PCBs and create our own hardware solutions for driving BLDC motors the proper low-cost solutions are yet to come. One of the reasons for this is the apparent complexity of writing the BLDC driving algorithms, Field oriented control (FOC) being an example of one of the most efficient ones.
The solutions that can be found on-line are almost exclusively very specific for certain hardware configuration and the microcontroller architecture used.
Additionally, most of the efforts at this moment are still channeled towards the high-power applications of the BLDC motors and proper low-cost and low-power FOC supporting boards are very hard to find today and even may not exist.
Therefore this is an attempt to:
- 🎯 Demystify FOC algorithm and make a robust but simple Arduino library: [Arduino *SimpleFOClibrary*](https://docs.simplefoc.com/arduino_simplefoc_library_showcase)
- Support as many motor + sensor + driver + mcu combinations out there
- 🎯 Develop modular and easy to use FOC supporting BLDC driver boards
- For official driver boards see [SimpleFOCBoards](https://docs.simplefoc.com/boards)
- Many many more boards developed by the community members, see [SimpleFOCCommunity](https://community.simplefoc.com/)

## Arduino code example
This is a simple Arduino code example implementing the velocity control program of a BLDC motor with encoder.
NOTE: This program uses all the default control parameters.
```cpp
#include
// BLDCMotor( pole_pairs )
BLDCMotor motor = BLDCMotor(11);
// BLDCDriver( pin_pwmA, pin_pwmB, pin_pwmC, enable (optional) )
BLDCDriver3PWM driver = BLDCDriver3PWM(9, 10, 11, 8);
// Encoder(pin_A, pin_B, CPR)
Encoder encoder = Encoder(2, 3, 2048);
// channel A and B callbacks
void doA(){encoder.handleA();}
void doB(){encoder.handleB();}
void setup() {
// initialize encoder hardware
encoder.init();
// hardware interrupt enable
encoder.enableInterrupts(doA, doB);
// link the motor to the sensor
motor.linkSensor(&encoder);
// power supply voltage [V]
driver.voltage_power_supply = 12;
// initialise driver hardware
driver.init();
// link driver
motor.linkDriver(&driver);
// set control loop type to be used
motor.controller = MotionControlType::velocity;
// initialize motor
motor.init();
// align encoder and start FOC
motor.initFOC();
}
void loop() {
// FOC algorithm function
motor.loopFOC();
// velocity control loop function
// setting the target velocity or 2rad/s
motor.move(2);
}
```
