RCRxWiShield.pde

OBSOLETE. Receives RCOIP commmands from a WiShield and uses them to set servo and digital outputs. This simple example handles 5 RCOIP receiver channels. Its configured like this: 4 Servos (receiver channels 0, 1, 2, 3) 1 Digital output (horn) (receiver channel 4)

// RCRxWiShield
//
// Sample RCRx RCOIP receiver
// Receives RCOIP commmands on a WiShield and uses them to set servo
// and digital outputs.
//
// This compiles to about 15300 bytes on Duemilanove, and will not fit in Diecimila.
//
// This simple example handles 5 RCOIP receiver channels. Its configured like this:
// 4 Servos (receiver channels 0, 1, 2, 3)
// 1 Digital output (horn) (receiver channel 4)
// which is consistent with the default setup of the RCTx iPhone app.
//
// However, almost any combination of up to a large number of channels can be used as you see fit.
// Output devices supported are:
// analog output pins
// digital output pins
// Servo
// AccelStepper speed
// AccelStepper position
// HBridge to drive 2 other outputs
//
// Also you can string varies objects together top modify channel values as
// they make their way from the receiver to an output:
// Limiter
// Inverter
// This can be used off the shelf with the RCTx transmitter app for iPhone
