Return Value

Return an error code. If the returned value is zero, it indicates a successful execution of this function.

Comment

This function must be called after a successful execution of EthercatMaster::begin(). This function is blocking and cannot be called in callback functions.

Example Code

#include "Ethercat.h"

EthercatMaster master;
EthercatDevice_CiA402 motor;

void setup() {
  Serial.begin(115200);
  while (!Serial);

  master.begin();
  motor.attach(0, master);

  motor.enableTouchProbe2(CIA402_TPMODE_FIRST_EVENT, CIA402_TPSRC_TP_INPUT, CIA402_TPTIMING_POS_EDGE);
  while (motor.isTouchProbe2ValueReady(CIA402_TPVALUE_POS_EDGE) == false);
  Serial.print("Touch probe position 2 positive value: ");
  Serial.println(motor.readTouchProbe2Value(CIA402_TPVALUE_POS_EDGE));
  motor.disableTouchProbe2();
}

void loop() {
  // put your main code here, to run repeatedly:

}
