An Introduction to USB Communication (Part 1)
USB (Universal Serial Bus) is an industry-standard used to specify cables, connectors, and protocols that are used for communication between electronic devices. Advantages: Self-configuring interface, no need for user configuration of speed, data protocol, etc.Capable of supplying power to small auxiliary devicesVarious communication speeds are supportedStandard connectorsError checking increases the
FreeRTOS: Using MCU Peripheral Drivers
Communication interfaces (I2C, SPI, UART, etc.) are some of the most commonly used microcontroller peripherals in embedded systems. In this introductory article, we will look at how low-level drivers for such peripherals can be used in FreeRTOS. Polled Drivers vs Interrupt-driven Drivers Based on the method used for getting information
