  Embedded Firmware Design Document Firmware  is often referred to as “software for hardware”. Firmware provides instructions to help hardware start up, communicate with other devices, and perform basic input/output tasks.  There are typically three levels of firmware: Low-level firmware: This firmware is usually stored in non-volatile memory chips like read-only memory (ROM) and one-time programmable (OTP) memory. These chips cannot be rewritten or updated, and the firmware is intrinsic to the hardware, such as a computer. High-level firmware: This firmware is deployed within flash memory chips and comes with more complex instructions that allow updates to be made. Subsystems: These are semi-independent devices that are part of a more extensive system. Firmware at this level is embedded within central processing units (CPUs), flash chips, and liquid crystal display (LCD) units. Types of firmware :  BIOS (Basic Input/Output System) :- The Basic Input/O...

  Commands to start a Project in Git Repository  :- 𝗴𝗶𝘁 𝗶𝗻𝗶𝘁 : This is the very first command you'll need to use when starting a new project. It initializes a new Git repository in your current directory. 𝗴𝗶𝘁 𝗰𝗹𝗼𝗻𝗲 <𝗿𝗲𝗽𝗼> : To work on an existing project, you'll want to clone (copy) it to your local machine. This command does that. Commands to 𝗠𝗮𝗸𝗲 𝗖𝗵𝗮𝗻𝗴𝗲𝘀 :- 𝗴𝗶𝘁 𝘀𝘁𝗮𝘁𝘂𝘀 : Before making or after making changes, it's good practice to check the status of your files. This command will show you any changes that are currently upstaged. 𝗴𝗶𝘁 𝗮𝗱𝗱 <𝗳𝗶𝗹𝗲𝗻𝗮𝗺𝗲> : After you've made some changes to your files, you'll want to stage them for a commit. This command adds a specific file to the stage. 𝗴𝗶𝘁 𝗮𝗱𝗱 . 𝗼𝗿 𝗴𝗶𝘁 𝗮𝗱𝗱 -𝗔 : Instead of adding files one by one, you can add all your changed files to the stage with one command. 𝗴𝗶𝘁 𝗰𝗼𝗺𝗺𝗶𝘁 -𝗺 "𝗖𝗼𝗺𝗺𝗶𝘁 𝗺𝗲𝘀𝘀𝗮𝗴𝗲" : Now that your ...
