[EthercatDevice_DmpHID_Generic]

Description

Check if the software RX FIFO for the specified UART port of the specified EtherCAT slave device in this library is full.

Derived Class:

Syntax

int uartRxQueueFull(int dev);

Parameters

  • [in] int dev
    The specified UART port of the EtherCAT slave device.
    • 0 for COM1.
    • 1 for COM2.

Return Value

Return whether the software RX FIFO in this library is full. If the FIFO on the COM port is full, the returned value is 1; if it is not, it is 0.

If the return value is smaller than 0, it means an error code.

Comment

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.

Example

#include "Ethercat.h"

EthercatMaster master;
EthercatDevice_QECR11HU9S slave;

void setup() {
  Serial.begin(115200);

  master.begin();
  slave.attach(0, master);
  Serial.print("RX FIFO is Full: ");
  Serial.println(slave.uartRxQueueFull(0));
}

void loop() {
  // ...
}
