Would I up the baud rate? |

This is a good question. I think the update speed depends on MobiFlight Connector reading and writing the arduino pin states, this is not the same as the baud rate. I have been thinking a bit of the same, but Mobiflight architecture was not designed to be realtime responsive with large amounts of data, as it is meant to track button and switch events and to drive warning lights and other outputs based on simulator events. That said, for example 7-segment leds do update quite fast even when you write the value to the sim and read it back, having a round trip, but I am not sure if it is fast enough still for force feedback? I have not gone that far with my experiments yet. I need to build a stick or pedals with potentiometer feedback and then just try how those work if I try to create a centering spring force for example, if it will be hopelessly laggy. What hardware are you using to drive the force? I experimented a bit with a H-bridge and brushed DC motor, but I am not at all sure if it would work with mobiflight update loop. I can see your pain point, also not being that much of a programmer, so being able to run the logic in mobiflight would be cool, but I am not sure if this is going to work in practice. |

values are sent to the arduinos every time they change. values are read from the sim in different ways depending on the flight sim. fsuipc connection requests the data with every loop through the output configs. sim connect receives the data as soon as it changes. xplane 10 times per second. However, the current values are only evaluated when an individual config item is executed because there are transforms and other manipulation possible. Bottom line, if you want to increase the responsiveness then you have the execution speed slider in the settings menu. the best value is to perform updates every 50ms or 20 times per second. |
