[Emc-users] HAL: input-output pin wired to a only input or only output pin
Hello, I want to connect the output of an AND gate, to the INDEX-ENABLE io pin of my card. I want too, to connect the INDEX-ENABLE io pin of AXIS to one of the inputs of the AND gate. Will this give an error or is it possible?. Thanks, Javier PD: Rationale: I want to reset two encoder counters using the index pulse of one of them. The electrical part is easy. At the HAL configuration level, I plan to connect the AXIS-INDEX-ENABLE io pin to the first CARD-INDEX-ENABLE io pin and to the second CARD-INDEX-ENABLE io pin, through an AND gate that has a ONE as the other input. The underlying reason is that I want to compare the errors between both sensors. -- WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.

If it doesn't work it should be fairly easy to write a HAL function to convert IO to I and O pins and vice-versa. I think you might have trouble with AND writing to the output IO pin every thread. A comp has the option of only writing to the pin when a condition is met, and leaving it unchanged otherwise. -- atp Torque wrenches are for the obedience of fools and the guidance of wise men -- WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
