Universal Asynchronous Receiver-Transmitter (UART) is one of the most fundamental and widely used interfaces in embedded systems. Whether you are debugging via logs, communicating with a sensor, or interfacing with a GSM module, UART is often the go-to protocol.

Introduction

// Enable RX interrupt (optional but useful) USART_IntEnable(UART_HANDLE, USART_IEN_RXDATAV); NVIC_EnableIRQ(USART0_RX_IRQn);
