StepperUNO Library 1.1

under construction...

Installation

Download the zip file from Stepper_UNO_v1.0#Files.
Copy the StepperUNO folder in the sketchbook/library directory.

Configuration

Open the config.h file in the library/stepperUNO folder.
Change the KEYPAD_VERSION value as needed. Value should be 0 1 or 2. If you do not know just try one or the other and see how the button reacts.

Function list

Keypad

If the keypad does not reply correctly on the left/right/up/down/select button then a calibration should be performed. Values should be changed in the .h file of the library.

uint8_t ReadKey();

Return which key is currently pressed.

Keys are defined as below:

#define BUTTON_NONE               0  // 
#define BUTTON_RIGHT              1  // 
#define BUTTON_UP                 2  // 
#define BUTTON_DOWN               3  // 
#define BUTTON_LEFT               4  // 
#define BUTTON_SELECT             5  //

Note. The RST button uses a different function.

bool RstReadKey();

Return if the RST button is pressed or not.

The RST button is a special case. It has its own pin to the arduino mcu.

bool buttonJustPressed;

//this will be true after a ReadButtons() call if triggered

bool buttonJustReleased;

//this will be true after a ReadButtons() call if triggered

bool rstbuttonJustPressed;

//this will be true after a ReadButtons() call if triggered

bool rstbuttonJustReleased;

//this will be true after a ReadButtons() call if triggered

Motor Control

void speed(int speed_m1);

Set the motor speed.

speed_m1 must be the delay between each step in milliseconds.

void setDirection(bool dir);

Set the direction.

void enable();

Enable the motor. Holds torque on the motor.

void disable();

Disable the motor. Allows the motor to spin freely.

void step();

Perform one single step.

void stop();

Stop the motor.

uint8_t address;

i2c address of the MCU controlling the motor. Usually 0x04 or 0x05.

void begin(uint8_t _address);

Initialiser to be used in Setup section of Arduino. address parameter is the i2c address of the motor controller. Usually 0x04 or 0x05.

bool running;

Indicates if the motor is running.

bool direction;

Indicates the motor direction.
