int currentWrite(int ch, double current);
Parameters
[in] int ch
The specified analog output channel on the EtherCAT slave device.[in] double current
The desired output current, in amperes (A).
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::start() and before EthercatMaster::stop(). This function is non-blocking and can be called within the callback functions.
Example
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_QECR11A44S slave;
void setup() {
master.begin();
slave.attach(0, master);
master.start();
}
void loop() {
slave.currentWrite(0, 0.02);
delay(1000);
slave.currentWrite(0, 0);
delay(1000);
slave.currentWrite(0, 0.01);
delay(1000);
slave.currentWrite(0, 0);
delay(1000);
