Structure​

struct uart_t {
    char * name;
    int (*set)(struct uart_t * uart, int baud, int data, int parity, int stop);
    int (*get)(struct uart_t * uart, int * baud, int * data, int * parity, int * stop);

Key API​

FunctionDescription
search_uart(name)Find UART by name
register_uart(uart, drv)Register a UART
unregister_uart(uart)Unregister a UART
uart_set(uart, baud, data, parity, stop)Configure serial port parameters
uart_read/write(uart, buf, count)Read/write data

Description​

Universal asynchronous receiver-transmitter interface. Configures baud rate, data bits, parity and stop bits, provides blocking read/write operations for byte stream communication.
