What Will I Learn?

• Write a bare-metal firmware for USB 2.0 human interface devices (HID) without using any third-party libraries or code generators.
• Implement USB device driver and USB 2.0 protocol framework.
• Program a fully functional USB mouse from zero.
• Understand the generic USB descriptors and the descriptors specific to human interface device (HID) class.
• Deal with native USB (WITHOUT any conversion to UART)
• Use ARM Cortex-M4 based microcontroller (STM32F4xx), one of the most developed and famous MCU in the world.
• Debug USB communication using Wireshark and Linux SysLog.
• Read different parts of ARM Cortex-M4 reference manual and extract the important information efficiently.
• Understanding how USB 2.0 protocol works in full speed mode.
• Understand USB endpoints, pipes, transfer types, packets, transactions, frames, power supply, topology, and many more.
• Learn the basic mechanical and electrical specifications of the USB (connectors, cables, speed enumeration resistors, and many more).
• Know the history and motivation behind developing the universal serial bus (USB).
• Learn using Single Wire Output (SWO) to send logs to the debugging host.
• Increase your productivity and code portability by using ARM CMSIS.
• Document your code using Doxygen syntax.

Requirements

• Basic knowledge of C programming language (recommended).
• Basic knowledge of designing embedded systems.
• Any STM32F4 Microcontroller (ARM Coretx-M4 based) on Discovery or Nucleo board to apply the knowledge.

Target audience

• Anyone who wants to understand how the complex USB systems work behind the scenes.
• Embedded engineers who want to develop USB devices.
• Engineers who want to enrich their knowledge in embedded systems in general.
• Engineers who want to write modular and maintainable firmware.
