[Ethercat Device]
Description
Write 8-bit value to the specified object for such EtherCAT slave device.
Syntax
int sdoDownload8(uint16_t od_index, uint8_t od_subindex, uint8_t value, uint32_t timeout_us = 100000);
Parameters
[in] uint16_t od_index
Index of the object.[in] uint8_t od_subindex
Subindex of the object.[in] uint8_t value
The 8-bit value to be written to object.[in] uint32_t timeout_us
Timeout in microseconds.
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;
void setup() {
Serial.begin(115200);
master.begin();
slave.attach(0, master);
master.start(1000000);
}
void loop() {
slave.sdoDownload8(0x6040, 0x00, 0x0F);
delay(1000);
