# Introduction 

This repository includes `uio` driver for `T113-S3 PWM` peripheral.  

# Directories

- `driver`: kernel space driver  

   It's basically platform device which is registered into `uio` framework. All register handling is done in user space.

- `lib`: user space library  

   Shared library for interfacing with `PWM` peripheral. 

- `app`: user space application  

   User space application which implement simple use case of library APIs.

- `udev`: Simple udev rule to create `/dev/uio0` device node with proper access. This way you don't need `root` access to use `uio` device.
