[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.

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() { // ... }
