This function must be called after a successful execution of EthercatMaster::start(). This function is non-blocking and can be called within the Cyclic Callback.
Example
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_Generic slave;
uint8_t *pointer;
void setup() {
master.begin();
slave.attach(0, master);
master.start(1000000);
pointer = slave.pdoGetOutputBuffer();
}
void loop() {
pointer[0] = 0x55;
delay(500);
pointer[0] = 0xaa;
delay(1000);
