I think CPU Cortex-M4 is a lot slower than arduino but without operating system they do nothing else than running application. These kind of micro controllers is what I am used with, they usually have the required hardware for control of a servo or ordinary electric motor or other periodic real time tasks. _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
