[Ethercat Device]
Description
Write a file to the EtherCAT slave device using FoE.
Syntax
int writeFoE(char *filename, uint32_t password, void *data, uint32_t size, uint32_t timeout_ms = 2000);
Parameters
[in] char *filename
Name of the file to be written.[in] uint32_t password
32-bit password value. If the password is equal to zero, it indicates that the password is unused.[in] void *data
The file data buffer to be written.[in] uint32_t size
The size of the file data buffer to be written.[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
The function must be called after EthercatMaster::begin(). This function is blocking and cannot be called within the Cyclic Callback.
Example
#include "Ethercat.h"
EthercatMaster master;
EthercatDevice_Generic slave;
char source[] = {"source.bin"};
char filename[] = {"firmware.bin"};
uint32_t password = 0;
uint8_t *filedata;
int filesize;
FILE *file;
void setup() {
master.begin();
slave.attach(0, master);
file = fopen(source, "rb");
if (file != NULL) {
fseek(file, 0, SEEK_END);
filesize = ftell(file);
fseek(file, 0, SEEK_SET);
filedata = (uint8_t *)malloc(filesize);
if (filedata != NULL) {
fread(filedata, sizeof(uint8_t), filesize, file);
slave.writeFoE(filename, password, filedata, filesize);
free(filedata);
}
fclose(file);
}
}
