Syntax
uint32_t digitalReadAll();
Parameters
None.
Return Value
Return a 32-bit unsigned integer that represents the combined state of all digital input pins. Each bit in the returned value corresponds to a digital input pin of the EtherCAT slave device, with the following mapping:
- Bit 0 indicates digital input pin 0.
- Bit 1 indicates digital input pin 1.
- And so on, up to bit 31 which indicates digital input pin 31.
A value of 1 indicates that the corresponding pin is currently HIGH, while a value of 0 indicates that it is currently 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.digitalWriteAll(0x55555555);
delay(1000);
Serial.print("DI: ");
Serial.println(slave.digitalReadAll());
slave.digitalWriteAll(0xAAAAAAAA);
delay(1000);
Serial.print("DI: ");
Serial.println(slave.digitalReadAll());
