Class _uarta: Universal Asynchronous serial Receiver Transmitter

A class _uarta object is a UART.

It is used in:

• ESP8266 : uart0 and uart1

Configuration

hw | hwa( configure, uart0,
 
          //  Transfer rate in bits per second
          //
        [   bps
          | baudrate,  BPS, ]
        
          //  Number of data bits in frame. Default is `8`.
          //
        [ databits,    5 | 6 | 7 | 8, ]
        
          //  Parity. Default is `none`.
          //
        [ parity,      none
                     | even
                     | odd, ]
        
          //  Number of stop bits in frame. Default is `1`.
          //
        [ stopbits,    1 | 2, ] );

Note You must connect the I/O pins to the proper UART signals using the configure action on the I/O pin.
