EthercatDevice_Generic slave;
uint32_t ErrorCode = 0;
void ErrorCallback(uint32_t errorcode) {
ErrorCode = errorcode;
}
void setup() {
Serial.begin(115200);
master.attachErrorCallback(ErrorCallback); // ErrorCallback Function.
master.begin();
slave.attach(0, master);
master.start(1000000, ECAT_SYNC); // 1000000 ns = 1 ms
