Return the raw data from the Encoder.
備註
This function must be called after a successful execution of EthercatMaster::start() and before EthercatMaster::stop(). This function is non-blocking and can be called within the callback functions.
範例
#include "Ethercat.h"

master.begin();
slave.attach(0, master);
master.attachCyclicCallback(CyclicCallback);
master.start();
}
void loop() {

if (raw != newRaw) {
raw = newRaw;
Serial.print("Raw: ");
Serial.println(raw);
