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.
|short getChar(const TUARTs nPort)|
|(short) Function will retrieve the next character from the buffer that was sent to port 'nPort'.
|void sendChar(const TUARTs nPort, short nChar)|
|(void) Function will send the next character to port 'nPort'.
|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.
|void configureSerialPort(const TUARTs nPort, TSerialPortMode nMode)|
|(void) This function will manually configure the serial port for a specific mode (system, user, Xbee, VEX LCD, etc). You can also set this same functionality using the "Motors and Sensor Setup" window.
|boolbXmitComplete(const TUARTs nPort)|
|(bool) Function will return if the transmit (Xmit) buffer is empty.
