Simplicity Studio Uart Example Apr 2026

// 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

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

// Simple string transmit function void uart_send_string(const char *str) while (*str) USART_Tx(UART_HANDLE, *str++);

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! simplicity studio uart example

// Initialize UART uart_init();

while (1) // Main loop does nothing – everything is interrupt driven __WFI(); // Wait for interrupt

// Initialize USART USART_InitAsync(UART_HANDLE, &init); // Configure USART pins (using location specific to

// 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");

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

Introduction

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

// Buffers char tx_buffer[64]; char rx_byte;
