+function RPI_pcf8591Setup(pinBase,i2cAddress)
+// Function for setting up 8-bit PCF8591 Analog IO expander IC
+//
+// Calling Sequence
+//  RPI_pcf8591Setup(pinBase,i2cAddress)
+//
+// Parameters
+//  pinBase   : any number above 64.The consecutive 4 pins will be allocated alongwith.
+//  i2cAddress: I2C address obtained using RPI_i2cdetect function
+//
+// Description
+//  This function sets up the extension module for the PCF8591 8-bit GPIO expander IC. Can be called multiple times for multiple PCF8591 using different pinBase for each.
+//
+//Specifying the number of pins is not necessary – the PCF8791 has 4 pins – the analog output uses base pin number 0 – the same as analog input 0.
+//
+// Examples
+//  RPI_pcf8591Setup(67,64)
