ARDUINOFunctions and Variables → ARDUINO MEGA Functions Serial Link


The Arduino MEGA has 4 user serial ports - 1 reversed for the system and 3 user controllable serial ports. These serial ports can be configured in code or via the Motors and Sensor Setup window. The serial ports are buffered as well, with a 70 byte receive buffer and a 40 byte transmit buffer.

Color Key
Function:
Variable:


getChar

short getChar(const TUARTs nPort)
(short) Function will retrieve the next character from the buffer that was sent to port 'nPort'.


Parameter Explanation Data Type
nPort A sensor port or name TUARTs


getChar(uartOne);  // retrieve the next char from UART Port 'uartOne'


sendChar

void sendChar(const TUARTs nPort, short nChar)
(void) Function will send the next character to port 'nPort'.


Parameter Explanation Data Type
nPort A sensor port or name TUARTs
nChar A char to send to 'nPort'. (Can be a short or a char) short


sendChar(uartOne, 'B');  // send the next char from UART Port 'uartOne'


setBaudRate

void setBaudRate(const TUARTs nPort, TBaudRate nBaudRate)
(void) Function will set the Baud Rate for port 'nPort'.

Acceptable Baud Rates: 1200, 2400, 4800, 9600, 19200, 38400, 57600, 115200, 200000, 230400 and 250000.


Parameter Explanation Data Type
nPort A sensor port or name TUARTs
nBaudRate The baud rate to use TBaudRate


setBaudRate(uartOne, baudRate9600);  // retrieve the next char from UART Port 'uartOne'
