[EthercatDevice_XXX]
Description
(CoE) Write the object to the EtherCAT Slave device. (unit8_t)
Format
int sdoDownload8(uint16_t od_index, uint8_t od_subindex, uint8_t value, uint32_t timeout_us = ECAT_DEFAULT_COE_TIMEOUT_US);
Syntax
EthercatDevice_XXX slave;
slave.sdoDownload8();
Parameters
uint16_t od_index
: CANOpen Object index.uint8_t od_subindex
: CANOpen Object sub-index.uint8_t value
: 1-byte Data.uint32_t timeout_us
: Timeout, unit for microsecond.
Returns
Int: 0 for successful; if the return value is smaller than 0 means error.
Example
#include "Ethercat.h" EthercatMaster master; EthercatDevice_Generic slave; void setup() { Serial.begin(115200); while (!Serial); master.begin(); slave.attach(0, master); /* Write 0x08 to the object with index 0x6060. */ slave.sdoDownload8(0x6060, 0x00, 0x08); /* Read value from the object with index 0x6061. */ Serial.prinln(slave.sdoUpload8(0x6061, 0x00)); master.start(); } void loop() {}
