[Ethercat Device]
Description
Write the data of SII EEPROM of a certain size which starting from the specified offset for such EtherCAT slave device.
Syntax
int writeSII(uint32_t offset, void *data, size_t len, uint32_t timeout_ms = 500);
Parameters
[in] uint32_t offset
The offset value of SII EEPROM for such EtherCAT slave device.[in] void *data
The data buffer for writing SII EEPROM.[in] size_t len
The size of the data buffer for writing SII EEPROM.[in] uint32_t timeout_ms
Timeout in milliseconds.
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 blocking and cannot be called within the Cyclic Callback.
Example
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_Generic slave;
uint8_t buffer[4] = {0x00, 0x55, 0xAA, 0xFF};
void setup() {
master.begin();
slave.attach(0, master);
slave.writeSII(64, buffer, 4);
}
void loop() {
// ...
