A USB mass storage gadget allows a device to emulate a USB storage device, such as a flash drive or external hard disk. This means you can connect your Raspberry Pi to another computer and have it appear as an external storage device. The benefits include:
Turn Your Raspberry Pi into a USB Keyboard (HID)
HID stands for Human Interface Device, a standard that allows devices like keyboards and mice to communicate with computers in a standardized way. By emulating an HID keyboard, your Raspberry Pi can send keystrokes to any compatible system, making it a powerful tool for automation, testing, or creating custom input solutions.
Virtual UART over USB (Raspberry pi)
In the world of embedded systems and hardware projects, establishing a reliable communication channel between devices is crucial. The USB UART gadget provides a simple yet powerful solution for interfacing microcontrollers, sensors, and other peripherals with a computer or host device. This article will guide you through the process of setting up a USB UART gadget, allowing you to leverage USB connections for serial communication.
Ethernet over Usb (Raspberry pi)
The Raspberry Pi is a versatile and popular single-board computer, ideal for a variety of projects ranging from home automation to media centers. While many users rely on Wi-Fi for internet connectivity, there are times when a wired connection can offer more stability and speed. Enter Ethernet over USB—a method…

EspNow protocol
ESP-NOW is a wireless communication protocol that enables low-power, low-latency data exchange between devices without the need for a traditional Wi-Fi connection. It operates over the 2.4 GHz band, allowing devices to communicate directly with one another in a peer-to-peer manner.
Cloning IR remote
Infrared communication relies on modulated light waves to transmit data between devices. An IR remote control typically sends a series of pulses (on and off signals) that represent binary data. To clone a remote, we need to capture these pulses and then replicate them.
Modbus: Bridging the Gap in Industrial Networking
Modbus is a widely used communication protocol in industrial automation, enabling devices to communicate over serial lines and Ethernet. Developed in the late 1970s by Modicon (now part of Schneider Electric), it has become a standard for connecting industrial electronic devices. Its simplicity, open nature, and reliability have made it the go-to choice for numerous applications.
Exploring Interrupts: Enhancing Performance in Embedded Systems
An interrupt is a signal to the processor emitted by hardware or software indicating an event that needs immediate attention. When an interrupt is received, the current execution of the program is paused, and control is transferred to a special routine called an “interrupt handler” or “interrupt service routine” (ISR). Once the ISR has finished executing, the processor resumes the program from where it was interrupted.
