Try connecting two devices together, or hook up a GPS module to parse NMEA sentences over UART. Have questions or want to see a DMA or low-power UART example? Let me know in the comments below! #include "em_device

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. communicating with a sensor

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

// Default USART configuration structure USART_InitAsync_TypeDef init = USART_INITASYNC_DEFAULT; init.baudrate = 115200; init.databits = usartDatabits8; init.parity = usartNoParity; init.stopbits = usartStopbits1;

Create a new file main.c and add the following code:
