EthercatDevice_DmpHID.uartSetRTS()

[EthercatDevice_DmpHID_Generic]

Description

Control the RTS signal for the specified UART port of the EtherCAT slave device.

Derived Class:

Syntax

int uartSetRTS(int dev, uint8_t value);

Parameters

• [in] int dev
  The specified UART port of the EtherCAT slave device.
  • 0 for COM1.
  • 1 for COM2.
• [in] unit8_t value
  The RTS signal value to be set.
  • 0: Indicates an inactive RTS signal.
  • 1 to 255: Indicates an active RTS signal

Return Value

Return an error code. If the returned value is zero, it indicates a successful execution of this function.

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 CyclicCallback() {
  slave.update();
}

void setup() {
  master.begin();
  slave.attach(0, master);
  master.attachCyclicCallback(CyclicCallback);
  master.start();
}

void loop() {
  slave.uartSetRTS(0, 1);
  delay(1000);
  slave.uartSetRTS(0, 0);
  delay(500);
  // ...
}
