[EthercatDevice_Dmp]
Description
Try to get the system current in a non-blocking manner. If it returns true, the reading process is complete, and you must immediately call getSystemPowerCurrent() to get the value. Otherwise, it indicates that the process is not yet complete.
Syntax
bool tryToGetSystemPowerCurrent();
Parameters
None.
Return Value
Return a boolean value indicating whether the non-blocking read process has completed.
- true: Completed.
- false: In progress.
Comment
This function must be called after a successful execution of EthercatMaster::begin(). This function is non-blocking and can be called within the callback functions.
Example Code
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_QECR11DT0H slave;
double SystemCurrent;
void CyclicCallback() {
if (slave.tryToGetSystemPowerCurrent())
SystemCurrent = slave.getSystemPowerCurrent();
}
void setup() {
Serial.begin(115200);
master.begin();
slave.attach(0, master);
master.attachCyclicCallback(CyclicCallback);
master.start();
}
void loop() {
Serial.print("System Current: ");
Serial.println(SystemCurrent);
// ...
