finder

Embedded Software Project

Description

This repository contains the embedded software project called "finder." The project focuses on controlling LED and MOTOR driver modules through a main program.

1. Target System Kernel Install - How to install the kernel on the Raspberry Pi 4B used in the project

   reference : https://wikidocs.net/3243 is how the kernel is built.

2. Components - The project consists of the following components

   Motor driver : Motor drivers to control the RC motors on each wheel of the vehicle

   LED driver : Led driver for controlling Leds with on/off functionality

Getting Started

Follow the steps below to get started with the "finder" project:

1. Clone this repository to your local machine.

2. Obtain administrator privileges

   $ sudo -i
   

3. In motor directory,

   # make
   # mknod /dev/motor_driver c 237 0
   # chmod ug+w /dev/motor_driver
   # insmod motor_driver.ko
   
   // in short,
   # make
   # make device
   # make chmod
   # make insert
   

4. In led directory,

   # make
   # mknod /dev/led_driver c 237 0
   # chmod ug+w /dev/led_driver
   # insmod led_driver.ko
   
   // in short,
   # make
   # make device
   # make chmod
   # make insert
   

5. In main directory on target system,

   # python3 cam.py
   

6. In main directory on target system,

   # make finder_run
   # ./finder_run [IP Address] [Port Number]
   

7. In main directory on client,

   # make finder_control
   # ./finder_control [IP Address] [Port Number]
   

8. Input "w", "a", "s", "d", "t", "r", "p" at client
