Throws:
_INSERT_METHOD_SIGNATURE_HERE_

baud rate of the UART port |
| parity |
UART.PAR_NONE UART.PAR_ODD UART.PAR_EVEN UART.PAR_FORCE1 UART.PAR_FORCE0 |
parity check |
| bits |
UART.BITS_5 UART.BITS_6 UART.BITS_7 UART.BITS_8 |
number of data bits |
| stop |
UART.STOP_1 UART.STOP_2 |
number of stop bits |
The UART communication parameter can be adjusted with the open(int, int, int, int) method once an instance of the UART class is created. All parameters for the UART communication are listed in the table above.
| Returns | Range | Description |
|---|---|---|
| opened | true ... false | whether the UART port can be opened or not |
The open() method returns true when the UART port can be opened.
Example
The following example opens the UART port.
if (uart.open(UART.baud_115200,UART.STOP_1,UART.BITS_8,UART.PAR_NONE))
Draw.writeText("the serial port is open");
