= About Your Project =


 * Project name: Beagle Config

Description

 * As we all know, nearly all of the user operations in Linux can be done using shell commands , scripts and Linux Userspace Api for advanced users. But all that being said for an average user and sometimes in production these steps can be repetitive and time consuming. For example- Simply sharing network i.e. editing iptables and enabling packet forwarding with Pocketbeagle is an uphill task without a script provided. However running scripts could be dangerous. Even adding a USB gadget without rcn-ee's boot script is definitely difficult.
 * Enabling the PRU and loading the firmware is much daunting and unless anybody goes through their usage Documentations it will be difficult.
 * Not only does it makes beagle devices more friendly but provides an edge to beagleboard over other similar platforms.
 * Hence I propose beagle-config which is a terminal based UI application that brings down the steep curve and enables anybody to config their beagle device as they wish.
 * Also while configuring sometimes if the script has hard coded values it makes difficult for the user to go back to default configurations. With beagle-config that won't be a problem anymore
 * Goal : Beagle-Config aims to provide the functionality to make the most common low level configuration changes in beagle devices easily and providing a terminal UI to do the same.

Implementation Details

 * Here are few details of the beagle-config which will use bash, C/C++ as back end for low level access to linux's userspace api and FTXUI for frontend.
 * All the below config options are stored in user's home directory with .beaglec
 * A restore to defaults option
 * Light Vs Dark theme chooser

System Options
The system options sub menu allows you to make configuration changes to various parts of the boot, login and networking process, along with some other system level changes.

This will enable hobbyists to enable / disable their PRUs if they want to test their PRU code in c or in simppru. Example - PRU Conf PRU 1 Enable Disable PRU 2 Enable Disable Enabling a GPIO pin for input/output Example - GPIO 18 - Enable Disable Set Value
 * PRU enable/disable
 * GPIO configuration

Enables users to share their host internet within a click Example - Host Host A                       Enable Internet Advanced Set IP gateway Return to Defaults Host Name          BBB Edit Country Code      
 * Internet Sharing and Client Configurations

Enables users to extend the sd card partition size if avaible Example - eMMC Storage       Total 52 % Free Extend
 * eMMC stats

For wireless enabled devices like beaglebone black wireless configuring Access Point names, mDNS configurations, etc
 * Wireless Configurations

If beagle bone has onboard sensors then enabling them, viewing stats like charging status, battery status , power consumption, etc.
 * Sensor Configurations

If beagle supports audio on board Specify Audio Output
 * Audio Configurations

Configure passwords along with addition of users, groups
 * Password

We can configure whether to boot in desktop mode or using just console enabled. Add option to login automatically.
 * Boot / Auto login

Configure the USR Leds on the board. Their frequency and events.
 * User LED

Display Options
Enable configuration of HDMI/DVI if the board supports it
 * Resolution

Interfacing Options
If a beagle board and its associated cape needs a configuration, this can be configured here easily.
 * Cape Configurations

Enable any standard camera interface and additional configurations
 * Camera

Configure ssh, enable / disable and setup password
 * SSH

Enable/disable SPI and I2C interfaces and automatic loading of the SPI / I2C kernel modules if there are any existing.
