+function RPI_SPISetup(channel,speed)
+// Function to initialize SPI
+//
+// Calling Sequence
+//  RPI_SPISetup(channel,spped)
+//
+// Parameters
+//  channel: channel number, 0 or 1
+//  speed  : SPI clock speed in Hz
+//
+// Description
+//  This function initialises a channel (The Pi has 2 channels; 0 and 1). The speed parameter is an integer in the range 500,000 through 32,000,000 and represents the SPI clock speed in Hz.
+//
+//The returned value is the Linux file-descriptor for the device, or -1 on error.
+//
+// Examples
+//  RPI_SPISetup(1,500000)
+// See also
+//  RPI_SPIDataRW, RPI_SPISetupMode, RPI_SPIGetFd
