[etherlab-users] ec_slave3.c

Wed Jul 4 10:19:43 CEST 2018

Hello,

As far as I know, you should not mex ec_slave3.c. Instead, you just need 
to update the (old) version of the file as was installed by Etherlab 
with a newer one. The file is automatically used during the build 
process in Simulink.

See https://www.symbitron.eu/wiki/index.php?title=EtherLab_Installation 
, there's a small section on that.

Please report if this helps for you.

Best,

Gijs van Oort
