static struct Uart<C> new(
    &volatile unsigned int base,
    unsigned int baud,
    unsigned int clock_hz,
)

source · definition

Initialize the UART at base: 8N1 at baud from a clock_hz input clock (0 = leave the rate the firmware set). The chip type comes from the target.

§void write_byte(unsigned char c)source · definition

Send a single byte (blocks until TX ready).

§unsigned char read_byte()source · definition

Read a single byte (blocks until RX available).

§void write_str(const &char s)source · definition

Send a null-terminated string.

§int rx_ready() constsource · definition

Check if a byte is available to read. Returns 1 if ready.

§int tx_ready() constsource · definition

Check if transmitter is ready. Returns 1 if ready.
