In the following sections I will briefly describe three examples of usage of the library.įor each example there are a figure describing the sequence of the movements executed by the stepper motor(s) and the respective source code.

Some getter methods to provide the state of the motor.

The possibility to set a maximum angle threshold (in absolute value) for the motor rotation.

5 speed modes allowed: from 20% to 100% of the maximum speed.

A setter method to run the motor according to direction, angle and speed provided by the user.

Then, connecting the stepper motors to the outputs of the drivers is very simple because there is only a small connector to plug in.

GND: physical pins 6 (for sm1) and 25 (for sm2) of the header.

+5V source: physical pins 2 (for sm1) and 4 (for sm2) of the header.

The following tables show the connections between the GPIO pins (on Raspberry Pi 1B, board revision 000f and on Raspberry Pi 3B, board revision a22082) and the four inputs of each stepper motor driver: BCM GPIO pin The instructions to obtain and install the WiringPi library can be found here.įinally, the last thing to do is to download and compile the Stepper motor library:

Let’s start with the installation of cmake and git with the following commands: Now we are ready to switch from the PC to the Raspberry Pi. The SD device node is usually something like /dev/mmcblk0.įor more details on the installation process you can read the documentation. Once you have downloaded and extracted the image, a quick way to flash it to your SD card on Linux is the one here below (do it as root):ĭd if=/home/your_user/Downloads/name_of_your_image.img of=/dev/your_SD_device_node I usually prefer a minimal installation in order to add the packages I need afterwards, so I opted for the lite version of Raspbian. Raspbian stretch lite)įirst of all you need to install an operating system on your Raspberry Pi.

A Linux distro installed onto the Raspberry Pi (i.e.

The driver needed, which is essentially composed by a certain number of NPN BJTs grouped in pairs and connected in darlington configuration, is the ULN2003APG. They cannot be connected directly to the GPIO header, so we need to put a driver between the Raspberry Pi and the motors, one for each motor.

The model of the stepper motors I used is the 28BYJ48.

A Raspberry Pi (models 1B and 3B, in my case).In this post I will try to describe in a simple way how to use the library, also with the help of some examples. Recently I’ve done the last change to the code. About two years ago I wrote a simple C++ class to drive a small stepper motor using the Raspberry Pi.
