備註

This function must be called after a successful execution of EthercatMaster::begin(). This function is non-blocking and can be called within the Cyclic Callback.

範例

#include "Ethercat.h"

EthercatMaster master;
EthercatDevice_QECR00UN01 slave;

void CyclicCallback() {
  slave.update();
}

void setup() {
  master.begin();
  slave.attach(0, master);
  slave.lcdInit(ECAT_LCD_ILI9341_1);
  master.attachCyclicCallback(CyclicCallback);
  master.start();

  slave.lcdFillTriangle(100, 100, 200, 200, 80, 220, 0xFFE0);
}

void loop() {
  // ...
}
