+Using the SPI Class
+^^^^^^^^^^^^^^^^^^^
+
+You can declare that you want to use SPI in your sketch by putting
+``HardwareSPI Spi(number);`` with your variables, where ``number`` is
+1 or 2, depending on which SPI you want to use. Then you can use the
+functions described in the next section. For example::
+
+ // Use SPI 1
+ HardwareSpi Spi(1);
+
+ void setup() {
+ Spi.begin(SPI_18MHZ);
+ }
+
+ void loop() {
+ // Get the next byte from the peripheral
+ uint8 byte = Spi.recv();
+ }
+
HardwareSPI Class Reference
^^^^^^^^^^^^^^^^^^^^^^^^^^^
-You can use the SPI interface by including a declaration ``HardwareSPI
-Spi(number);`` at the start of the sketch or program. The ``number``
-must be either 1 or 2 and specifies which port to use. Once this is
-done, you can call any of the methods documented here using
-``Spi.method(arguments)``; for example, ``Spi.send(0x13)`` would send
-the value ``0x13`` into the port buffer to be transmitted as soon as
-possible.
