Simplicity Studio Uart Example -

// Initialize USART USART_InitAsync(UART_HANDLE, &init);

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

int main(void) // Chip initialization (important for errata) CHIP_Init(); simplicity studio uart example

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

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

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.

// 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 // Buffers char tx_buffer[64]

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