Simplicity Studio Uart Example Today

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.

// Initialize USART USART_InitAsync(UART_HANDLE, &init); simplicity studio uart example

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

// Buffers char tx_buffer[64]; char rx_byte; or interfacing with a GSM module

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

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!
