uStepper S-lite

The library contains support for driving the stepper, reading out encoder data. A few examples are included to show the functionality of the library. The library is supported and tested with in Arduino IDE 1.8.13.

Installation

Installation is split into two parts - Hardware and Library. Both are required to use the uStepper S-lite boards.

Hardware Installation

Instructions for users with the hardware for the original uStepper installed

To add hardware support for uStepper in the Arduino IDE (1.8.5+) do the following:

• Open Arduino
• Go to "Tools->Board->Boards Manager..."
• Search for "uStepper"
• Choose the "uStepper" board and press "Remove" button
• close the Boards Manager
• Go to "File->preferences"
• Almost at the bottom there is a field stating: "Additional Boards Manager URLs" replace your currently inserted uStepper URL this URL: https://raw.githubusercontent.com/uStepper/uStepperHardware/master/package_ustepper_index.json
• Press OK
• Go to "Tools->Board->Boards Manager..."
• Go to the bottom (after it has loaded new files) select "uStepper by ON Development IVS" and press install

Instructions for users new to uStepper

To add hardware support for uStepper in the Arduino IDE (1.8.5+) do the following:

• Open Arduino
• Go to "File->preferences"
• Almost at the bottom there is a field stating: "Additional Boards Manager URLs" insert this url: https://raw.githubusercontent.com/uStepper/uStepperHardware/master/package_ustepper_index.json
• Press OK
• Go to "Tools->Board->Boards Manager..."
• Go to the bottom (after it has loaded new files) select "uStepper by ON Development IVS" and press install

You have now added uStepper hardware support and should be able to select uStepper under tools -> boards.

Library Installation

To add the uStepper S-lite library do the following:

• Open Arduino IDE (Version 1.8.5 or above)
• Go to "Sketch->Include Library->Manage Libraries..."
• Search for "uStepper S-lite"
• Select "uStepper S-lite" and press install
• Close Library Manager
