EasyCAT Arduino shield

I see, the "-m" flag makes it write the pdos.
But what about the sdos? I don't see them coming over.

I haven't seen it yet either but I haven't used it yet either

The xml to eeprom translation is a missing piece. With the pdos and sdos. Siitool comes halfway.
Currently I see no other option than to use TwinCAT. If there was a way for TwinCAT to only do
the translation of xml into an eeprom binary file that would help. But no, I have to take out the card
from the machine and bring it to the Windows/Twincat machine and flash the eeprom from the xml file
with TwinCAT.

If you like JavaScript, you can start from the eeprom_generator which already can do the eeprom content,
without pdos and sdos again. There is a src/generators/EEPROM.js you can have a look at.
EasyCAT uses LAN9252 I have read so should be directly usable.

already a good starting point

new discovery, there is no sdos data in the eeprom.

could not find any in the documentation or in a sanmotion servo eeprom, the data is probably read from the firmware.

You are right.
I read out eeprom from a slave I know has SDOs.
But nothing with the SDO names in the eeprom bin file.
So, it is possible the siitools -m could produce a good eeprom.
I'll test later this evening, I have a device I can experiment with.
