The EtherCAT drive doesn't interface directly to HAL, does it? The actual register size transmitted down the wires is defined in the ethercat driver. Inside the code the _only_ variables which would need to change type are those whose pointers are passed to the hal_pin_new*() functions. And in any code written correctly, that would happen automatically if the hal_*_t definitions are changed. In fact, in your sample code, the unsigned int Word _can't_ be being used as a HAL pin, as it's a simple int, not a pointer. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-developers mailing list Emc-developers@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-developers
