Syntax
int uartGetCTS(int dev);
Parameters
[in] int dev
The specified UART port of the EtherCAT slave device.- 0 for COM1.
- 1 for COM2.
Return Value
Return the current state of the CTS signal. 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 CyclicCallback() { slave.update(); } void setup() { Serial.begin(115200); master.begin(); slave.attach(0, master); master.attachCyclicCallback(CyclicCallback); master.start(); } void loop() { Serial.print("CTS: "); Serial.println(slave.uartGetCTS(0)); delay(1000); // ... }
