Syntax
int digitalRead(int pin);
Parameters
[in] int pin
The digital input pin number of the EtherCAT slave device.
Return Value
Return the digital logic level of the specified digital pin. The value is HIGH or LOW.
Comment
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.
Example
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_QECR00D88D slave;
void setup() {
Serial.begin(115200);
master.begin();
slave.attach(0, master);
master.start();
}
void loop() {
slave.digitalWrite(0, HIGH);
delay(1000);
Serial.print("DI0: ");
Serial.println(slave.digitalRead(0));
slave.digitalWrite(0, LOW);
delay(1000);
Serial.print("DI0: ");
Serial.println(slave.digitalRead(0));
