FIXME [0.0.12/Maple Native] UART4, UART5 - -To use a serial port to communicate with an external serial device, -connect the TX pin to your device's RX pin, the RX to your device's TX -pin, and your Maple board's ground to your device's ground. - -.. warning:: Don't connect these pins directly to an RS232 serial - port; they operate at +/- 12V and can damage your board. - -Library Documentation ---------------------- - -.. FIXME [0.1.0] Tutorial-style usage introduction - -All of the ``Serial[1,2,3]`` objects are instances of the -``HardwareSerial`` class, which is documented in this section. (This -means that you can use any of these functions on any of ``Serial1``, -``Serial2``, and ``Serial3``). - -.. cpp:class:: HardwareSerial - - Serial port class. Predefined instances are ``Serial1``, - ``Serial2``, and ``Serial3``. - -.. cpp:function:: HardwareSerial::begin(unsigned int baud) - - Set up a ``HardwareSerial`` object for communications. This method - must be called before attempting to use the ``HardwareSerial`` - object (typically, you call this in your :ref:`setup() - <lang-setup>` function). - -.. cpp:function:: HardwareSerial::end() - - Disables the USART associated with this object, allowing any - associated communication pins to be used for other purposes. - -.. cpp:function:: unsigned int HardwareSerial::available() - - Returns the number of bytes available for reading. - -.. cpp:function:: unsigned char HardwareSerial::read() - - Returns the next available, unread character. If there are no - available characters (you can check this with :cpp:func:`available - <HardwareSerial::available>`), the call will block until one - becomes available. - -.. cpp:function:: HardwareSerial::flush() - - Throw away the contents of the serial port's receiver (RX) buffer. - That is, clears any buffered characters, so that the next character - read is guaranteed to be new. - -.. cpp:function:: HardwareSerial::print(unsigned char b) - - Print the given byte over the USART. - -.. cpp:function:: HardwareSerial::print(char c) - - Print the given character over the USART. 7-bit clean characters - are typically interpreted as ASCII text. - -.. cpp:function:: HardwareSerial::print(const char *str) - - Print the given null-terminated string over the USART. - -.. cpp:function:: HardwareSerial::print(int n) - - Print the argument's digits over the USART, in decimal format. - Negative values will be prefixed with a ``'-'`` character. - -.. cpp:function:: HardwareSerial::print(unsigned int n) - - Print the argument's digits over the USART, in decimal format. - -.. cpp:function:: HardwareSerial::print(long n) - - Print the argument's digits over the USART, in decimal format. - Negative values will be prefixed with a ``'-'`` character. - -.. cpp:function:: HardwareSerial::print(unsigned long n) - - Print the argument's digits over the USART, in decimal format. - -.. cpp:function:: HardwareSerial::print(long n, int base) - - Print the digits of ``n`` over the USART, in base ``base`` (which - may be between 2 and 16). The ``base`` value 2 corresponds to - binary, 8 to octal, 10 to decimal, and 16 to hexadecimal. Negative - values will be prefixed with a ``'-'`` character. - -.. cpp:function:: HardwareSerial::print(double n) - - Print ``n``, accurate to 2 digits after the decimal point. - -.. _lang-serial-println: - -.. cpp:function:: HardwareSerial::println(char c) - - Like ``print(c)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println(const char *c) - - Like ``print(c)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println(unsigned char b) - - Like ``print(b)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println(int n) - - Like ``print(n)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println(unsigned int n) - - Like ``print(n)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println(long n) - - Like ``print(n)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println(unsigned long n) - - Like ``print(n)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println(long n, int base) - - Like ``print(n, b)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println(double n) - - Like ``print(n)``, followed by ``"\r\n"``. - -.. cpp:function:: HardwareSerial::println() - - Prints ``"\r\n"`` over the USART. - -.. cpp:function:: HardwareSerial::write(unsigned char ch) - - Sends one character over the USART. This function is currently - blocking, although nonblocking writes are a planned future - extension. - - This is a low-level function. One of the ``print()`` or - ``println()`` functions is likely to be more useful when printing - multiple characters, when formatting numbers for printing, etc. - -.. cpp:function:: HardwareSerial::write(const char* str) - - Send the given null-terminated character string over the USART. - - This is a low-level function. One of the ``print()`` or - ``println()`` functions is likely to be more useful when printing - multiple characters, when formatting numbers for printing, etc. - -.. cpp:function:: HardwareSerial::write(void *buf, unsigned int size) - - Writes the first ``size`` bytes of ``buf`` over the USART. Each - byte is transmitted as an individual character. - - This is a low-level function. One of the ``print()`` or - ``println()`` functions is likely to be more useful when printing - multiple characters, when formatting numbers for printing, etc. - -Arduino Compatibility Note --------------------------- - -Unlike the Arduino, none of the Maple's serial ports is connected to -the USB port on the Maple board. If you want to communicate using the -built-in USB port, use :ref:`SerialUSB <lang-serialusb>` instead. You -will need an additional USB-to-serial adapter to communicate between a -USART and your computer. - -.. FIXME [0.1.0] port these examples over - -..
