function RPI_pwmWrite(pin,value)
// Function to write voltage value to the PWM register for the given pin.
//
// Calling Sequence
//  RPI_pwmWrite(pin,value)
//
// Parameters
//  pin  : The pin number set the voltage at. Numbering sequence to be followed as initiated using RPI_pinNumbering function.
//  value: The voltage to set at the given pin. Range is 0-1024.
//
// Description
//  Writes the value to the PWM register for the given pin. The Raspberry Pi has one on-board PWM pin, pin 1 (BMC_GPIO 18, Phys 12). Other PWM devices may have other PWM ranges.
//
// Examples
//  RPI_pwmWrite(1,500)
// See also
//  RPI_pwmMode, RPI_pwmRange, RPI_pwmClock, RPI_pwmToneWrite
