Simplicity Studio Uart Example [TRUSTED]

// Function to initialize UART void uart_init(void) // Enable clock for USART CMU_ClockEnable(UART_CLOCK, true);

#include "em_device.h" #include "em_chip.h" #include "em_cmu.h" #include "em_gpio.h" #include "em_usart.h" #include <string.h> // USART instance – change to your selected peripheral #define UART_HANDLE USART0 #define UART_CLOCK cmuClock_USART0

// Initialize UART uart_init();

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

// Configure USART pins (using location specific to your board) // For example: Route TX to PA0, RX to PA1 GPIO_PinModeSet(gpioPortA, 0, gpioModePushPull, 1); // TX GPIO_PinModeSet(gpioPortA, 1, gpioModeInput, 0); // RX simplicity studio uart example

// Send welcome message uart_send_string("Simplicity Studio UART Example\r\n"); uart_send_string("Type something, and I will echo it back:\r\n");

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! // Function to initialize UART void uart_init(void) //
