Simplicity Studio Uart | Example

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

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

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. simplicity studio uart example

// Initialize UART uart_init();

// Initialize USART USART_InitAsync(UART_HANDLE, &init); // Function to initialize UART void uart_init(void) //

// 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

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

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

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